    Ultra High quality laminations, lower inductance and superior sound. These transformers were especially designed and tested with several low-output moving coil cartridges. These are very difficult transformers to construct and require a precision manufacturing process that can only be done by David Geren at CineMag. The same construction techniques are used as in the 1131, except that the inductance of the SKY 30 is even lower due to the lower step up ratios.


    Hand Crafted, Moving Coil (MC) Cartridge Step-up Transformer (SUT) built with new CineMag SKY 30 (Blue Version) Transformers and gold plated hardware in a hand polished black powder coated cast-aluminum enclosure. All lettering is laser etched. Included are 2 switches: high/low gain and ground/lift.


    Includes premium construction with C&K Brand Silver contact toggle switches, and Deluxe Gold Plated RCA jacks.


    These specially designed transformers are wired to connect a moving coil cartridge (on a turntable) to a phono preamplifier, phono input of a receiver, or your preamp's phono input.


    Switchable for 1:15 (24 dB gain) or 1:30 (30 dB gain).


    Into a standard 47k phono preamp, the effective input impedance of the low gain (1:15 ratio) is 209 ohms. At 1:30, the effective input impedance is 52 ohms.


    The 1:30 ratio is perfect for most low output cartridges.


    Construction Techniques:

    All connections are Resistance soldered using the American Beauty system which avoids heat damage to the delicate insulation on the hair-like wires of the transformers. Test equipment is very low current to avoid saturating the transformer cores. You can count on a premier product that is state-of-the-art.


    This unit includes a grounding post that can be used to connect your turntable ground and your preamplifier ground. It also includes a ground lift switch. In all modes, the transformer cases and faraday shield internal to the transformers are connected to the ground screw. In the ground mode, the phono system minus sides (negative sides) are connected to the grounding lug. This configuration works well for those systems where the turntable ground is connected to the negative leads coming from the phono cartridge or where the negative inputs to the preamp are internally connected to ground. In the lift mode, none of the conductors in the RCA jacks are connected to the case, ground, or shield and there is no electrical connection between channels. This design allows you much flexibility to mitigate for ground loops regardless of the configuration of your other equipment.

    Have a question about this product? Please email our audio advisor or call 1-877-929-8729 with any questions or concerns regarding your equipment purchase.


    In continuation of the Ortofon design tradition and the new paradigm in engineering and manufacturing, we are proud to introduce the MC Windfeld Ti, a new moving coil phono cartridge in the absolute high-end class.


    At the heart of the MC Windfeld Ti lies a revolutionary customized Selective Laser Melting manufacturing technology pioneered by Ortofon for manufacturing of the legendary MC A90 in 2008. The use of Titanium in the MC Windfeld Ti has provided a further improvement to the overall rigidity of the structure and the cartridge weight.


    Our extensive knowledge of vibration properties, characteristics in different shapes and materials, competences in magnetism, mechanical design and new technologies has been applied for optimization of the MC Windfeld model. The new MC Windfeld Ti has gone to the next level by reducing unwanted vibrations and increasing the dynamic capability of the cartridge.


    Those who choose to adopt the MC Windfeld Ti will experience the lifelike, dynamic and open sound, with exceedingly clear midrange. The MC Windfeld Ti remains extremely musical while paying close attention to micro dynamic details, with its delicate, but also analytical nature.

    The mechanical integration of the MC Windfeld Ti


    Historically, Ortofon has always followed its own path with regard to the mechanical design of the cartridge housing, because mechanical rigidity and total freedom from resonance in the audible range are a precondition for optimal sound quality.


    In the MC Windfeld Ti the cartridge's contact with the tonerarm takes place through three hard, well-defined contact points placed on the fastening section of the cartridge. This means that the mechanical integration of the cartridge and the tonearm arm are always absolutely perfect.


    Flexibility and performance with a range of compatibility


    With optimized weight and moderate compliance to suit the majority of modern tonearms, the MC Windfeld Ti is easy compatible with an endless array of contemporary high-end turntable equipment, including the Ortofon TA-210 and TA-110 tonearms.


    A low output impedance of 7 ohm and a medium output voltage of 0.2 mV makes the Ortofon MC Windfeld Ti a perfect partner for most MC pre-amps as well as step-up transformers, including the Ortofon ST-80 SE.


    When combined with Ortofon's world-class knowledge in analogue sound reproduction, The MC Windfeld Ti will undoubtedly provide sound which is literally unsurpassed and simply has to be experienced.

    Rega Ios Moving Coil Amplifier

    40th


    Have a question about this product? Please email our audio advisor or call 1-877-929-8729 with any questions or concerns regarding your equipment purchase.


    Designed as the ultimate MC phono stage and the perfect match for the Rega Apheta MC cartridge Ios has made the transition in to the reference style case to match Isis and Osiris. The new Ios has the addition of balanced XLR connections mute and mono functions. The PCB layout has been redesigned to improve the noise floor and the entire unit has been fully rewired with ultra low capacitance cabling.


    The function of a phono pre amplifier is to match the output from a pick up cartridge to the input of a line level amplifier. It is required to amplify the very low signals produced by the cartridge and also to equalise the sound in accordance with RIAA record cutting standard. Rega believes that moving coil and moving magnet cartridges require different types of phono pre amplifiers to achieve optimum performance. The IOS is therefore dedicated to moving coil cartridges and avoids compromises. We have avoided including any superfluous functions as they obstruct the signal path and degrade the sound quality.


    Design innovation


    The Rega Ios is a four stage all symmetrical amplifier. To provide optimum performance it is dedicated to amplifying the very low level signals that are generated by moving coil cartridges.


    The first stage uses a 1:10 step-up transformer, which can be optimised to the cartridge by the selection of the correct loading and zobel DC resistance correction network connected across the MC transformer secondary.


    The second stage is a symmetrical compound pair class A amplifier, using paralleled low noise Hitachi transistors in the input stage.This drives the passive high frequency part of the RIAA equalisation stage.


    The third stage is a symmetrical class A differential amplifier with a common base driver stage; this is also used as the active amplifier in the low frequency part of the RIAA equalisation stage. The fourth stage is the active filter, this configuration uses the same circuit as found in the second stage. The filter element uses a very high bandwidth operational amplifier.


    The power supply is a symmetrical discrete tracking power supply using fast diodes and a low noise voltage reference. Each stage has its own localised power supply, and LED referenced current generators. Very high quality, polypropylene capacitors have been used in the signal path. 1% tolerance polypropylene capacitors are used in the RIAA EQ stages and audio grade capacitors are used in the rest of the circuit.


    We hope that you enjoy this product as much as we have enjoyed creating it. - Rega

    Manley Steelhead RC Phono Stage

    Stereophile Product The 2003 Four


    Have a question about this product? Please email our audio advisor or call 1-877-929-8729 with any questions or concerns regarding your equipment purchase.


    Handcrafted in the USA


    We debuted to the world a killer frikkin' cool phono stage at CES 2001. It was called, aquatic naming theme continuing, The SteelheadĀ®, as it is an upstream device and has a very clever MC variable load auto tranny that we designed and our very own Manley Magnetics department executed (which makes the MC stage so very clever). Iron=transformer=steel makes sense to me...


    It has two Moving Coil inputs with selectable impedance load 25, 50, 100, 200 and 400 Ohms via Mr. Clever Steelhead transformer/autoformer. It also has variable and selectable Moving Magnet input impedances too 25, 50, 100, 200 Ohms and 47 kOhms. Very nifty is the selectable-dial-able-in-able-from-the-faceplate-able capacitive loading for all three of the MM & MC inputs 0 to 1100 picofarads in 10 picofarad steps. Very cool! Equalize baby! TEN picofard steps! Wow! Now you can really dial this in for perfect cartridge matching with ZERO penalty. None of this switching detracts from the sound quality or adds any extra anything to the signal path. Rest assured.


    It's got six tubes. 2 x 6922 plus 4 x 7044 or 5687. It's got a big honkin' volume control. It can drive an amplifier directly if you want, if you don't do digital. Hey and if you happen to have three turntables set up, we give you 2 x MC and 1 x MM selectable inputs! It's got variable and fixed volume outputs. And All-tube really low Z tube buffered outputs. Like inherently 20 Ohms plus the little 47 Ohm OK drive those high capacitance audiophile cables why doncha resistor, so it's real output impedance is only 67 Ohms. No wanky cathode follower (oh bor-ing) output here like the other guys. We got your real low impedance all-tube outputs right here! It will drive anything and everything. Long cables, no problem.


    It's got selectable gain 50, 55, 60, 65dB on a switch that even auto-mutes as you change it so no nasty bangs. Gain switch markings are referred to from the input of the 1st active electronics at 1 kHz to the fixed output @ 10k load, regardless of whether source is MM or XFMR stepped-up MC. It is not really practical to include MC step-up gain on the front panel markings due to the variable SOURCE impedances of the MC cartridges and the variable LOADING that the input XFMR will have on any given cartridge. All of this total MC gain variability should be confined to about 3 to 12 dB of range though. XFMR step-up gain plateaus as the load Z on a given MC cartridge is optimised...producing no VOLTAGE gain but in fact a bit more POWER gain... All this means you should set a load Z which sounds best with your particular MC cartridge and adjust gain to suit your system's operating level. Whatever you like. You will not blow anything up.


    (Bottom line: there is plenty of gain... enough to do justice to your fave lo-output MC cartridges).


    It's got a mute switch. It's got a just turn it down while I cue up so I don't throw my woofer cones across the room but I still want the same volume I was listening at before I flipped the side DIM switch. And what goes with DIM better than SUM which would be the MONO button... It has a killer hyper-regulated outboard power supply that plugs in on the huge-est connector you ever saw. And you can just hit the standby button to keep everybody off while you take a small holiday to Tahiti. A backlit MANLEY STEELHEAD illuminated badge reflects back to vinyl-days-of-yore while the millions of BLUE LEDs remind you that this is modern tube engineering design, baby!


    The VARIABLE Outputs are controlled by the precision film dual NOBLEĀ® volume control. They are SMOOTH action these days as the fashion went against the detented ones.


    This is a tweak-o-holic tube-lover's dream...

    Evolution 100A





    To maintain a family resemblance with the lower powered amplifier, the EVOLUTION 100A is housed in a similar slim case with engraved front panel and solid metal control knobs as the EVOLUTION 50A. It is available with either a Black or Silver brushed aluminium front panel and uses the same ingenious soft push button design as the EVOLUTION 50 series, offering excellent tactile feel and backlit optical indication of functions, for optimum user-friendliness.


    The front panel features a large OLED (Organic Light Emitting Diode) display. The white on black display provides higher clarity and resolution than a normal display and has a wide range of customised graphic symbols. Display brightness levels can be changed or turned-off, if not required, via the menu system.


    In addition to greatly increased performance, thanks to ingenious new circuit design, the EVOLUTION 100A has been equipped with 2 sets of high quality loudspeaker binding posts, with local and remote switching for A & B outputs. Optional extras include the ability to plug the Sequel mk2 Phono pre-amp inside and add the AMBIT FM/AM radio or RUBY DAC/Bluetooth/FM radio module to the expansion slot on the rear panel.


    At the heart of any high-end amplifier there must be a good power supply; The EVOLUTION 100A uses a massive 360 Watt, low profile, toroidal mains transformer, with multiple windings for high and low voltages and current, to separate the power amp, pre-amp and digital circuitry. Creek's long-standing design policy of paralleling several small capacitors in the power supply creates an ultra-high specification capacitor, with low inductance and ultra low impedance. This significantly improves filtering and helps produce a very powerful and accurate sound from such a relatively small amplifier.


    After testing several methods of building a high performance and high efficiency power amplifier, suitable for this new model, David Gamble - Creek Audio's Senior Engineer - created a unique Class G circuit especially for the EVOLUTION 100A. David chose to use four Sanken STD03 complimentary power Darlington transistors per channel, as used in the EVOLUTION 50A, which feature built-in thermal compensation. Compared to the EVOLUTION 50A, he improved the performance of the voltage gain circuitry, which, in combination with the output stage, now achieves extremely high open-loop gain and exceptionally low distortion, without sacrificing stability. The result is an exceptional power amplifier circuit with very low output impedance and high output current capability. This combination provides exceptional speed and control suitable for driving most loudspeakers.


    To increase the power output of the smaller EVOLUTION 50A, yet still retain the same case size, David Gamble developed a cunning Class G circuit which runs normally at a lower voltage for power levels up to 25 Watts into 8 Ohms. When required to produce more than 25 Watts, the amp automatically swings to a higher secondary voltage, to increase the output power capability to over 100 Watts into 8 Ohms.


    Statistically, average audio signals are mostly below half the maximum voltage swing available, which incidentally is only one quarter of the power. As the dissipation of lossy 'idle current' in a Class A/B amp (in the form of heat) is much lower for a 25 Watt amp than the potential 100 Watts in the EVOLUTION 100A, this solution dramatically improves the amplifier's thermal efficiency and helps to keep it slim and attractive.


    The Pre-amp circuit provides high levels of flexibility and control, via unbalanced or balanced inputs. It has multiple input options, switched either electronically or by gold contact relays. It also has a State-of-the-Art electronic Volume, Balance and Tone controls. Volume control and op-amp circuit outputs are all buffered with constant current sources, to provide improved load tolerance and stable distortion characteristics.


    Correct grounding is difficult, if not impossible, in an un-balanced amplifier, so Creek has provided the consumer with a balanced line input for both the pre-amp and power amp input. In addition, the optional RUBY DAC module also benefits from having a dedicated balanced audio connection to the EVOLUTION 100A's pre-amp, via its flat foil cable, to avoid potential ground loops inside the amplifier.


    It is a modern listening trend for headphones to now be fed from low voltage sources, such as smart-phones and portable music storage devices. This required the development of low impedance headphones, to draw the required current to make them loud enough to satisfy the consumer. This trend has also necessitated a re-think of circuitry used in modern Hi-Fi amplifiers, to drive such low impedance headphones, together with the traditional medium to high impedance versions also.


    Creek Audio has taken the unusual step of driving the headphone output socket of their EVOLUTION amplifiers from a dedicated low impedance source. Instead of the headphone output being sourced from the power amplifier, the headphone output is derived from a dedicated amplifier, with only a few Ohms in series for protection against short circuits. This dedicated HP amp is now located on the pre-amplifier circuit board.


    Creek Audio no longer makes a separate FM Tuner, but die-hard analogue tuner fans can continue to enjoy this valuable format by using the top-quality AMBIT plug-in tuner module, which augments the EVOLUTION 50A and 100A's capabilities. The AMBIT or RUBY modules are mounted on the back panel 'Smart-Slot', replacing Line Input 5. When the AMBIT is fitted, it automatically turns the amp into a Receiver, configurable for use in any region of the world. The OLED display shows all the tuner's functions and it's controlled by the left hand buttons and control knobs, as well as remote control.


    For vinyl fans, the EVOLUTION 100A can also be configured for Vinyl Disc input, using Line input 1. A SEQUEL 2 (40, 48 or 54) module can be plugged into a dedicated connector on the pre-amp PCB. It doesn't restrict the use of either the AMBIT or RUBY modules. Sequel 2 comes in three versions - 40dB MM, 48dB MC and 54dB MC.


    To simplify the many options a stylish system remote handset controls all the functions of the EVOLUTION 50 and 100 series. An optional IR extender to enable the products to be hidden away, but still operable via remote control.


    The EVOLUTION 100A is the most sophisticated and reasonably priced amplifier Creek has ever made. It provides stunning audio performance and is capable of out-performing other makes of amplifiers costing many times the price.
