CYRUS Phono Signature - HiFi+ (UK)
  • Cyrus Phono Signature has received another glowing review, this time from Alan Sircom at Hi-Fi +. He says:
  • "In the Phono Signature, Cyrus has made an outstanding phono stage, one that combines the need for a holographic soundstage and massive amounts of detail, and one that gives a musical, engaging presentation...and all points in between."
  • With the addition of PSX-R₂ he said that as a combination this system can take on some of the real heavyweights! Alan says: "Recordings opened up under the watchful gaze of Phono Signature with ease, and the gentle tonal adjustment of cartridge loading can bring out the hidden gems within your record collection."
  • He listened to a variety of tracks including 'America is Waiting' from Eno and Byrne's 'My life in the Bush of Ghosts'. In his conclusion Alan says:
  • "The Cyrus Phono Signature surprised me. I expected it to be good. I just didn't expect it to be this good! Coupled with the PSX-R₂ it's a true world-beater; dynamically free, detailed and most of all so damn enjoyable to sit in front of..."'

CYRUS Phono Signature - The Ear (UK) review
  • If you're looking for a good read take a look at the fantastic review that The Ear gave Phono Signature. A full 5 stars! Phono Signature was reviewed by Jason Kennedy and Rene van Es with and without the addition of PSX-R2:
  • Jason: "Tom Waits’ Swordfishtrombones turned out to be even better than I thought it was, and I thought it was good, but the depth that the Cyrus reveals is remarkable."
  • "Overall the Phono Signature is an excellent phono stage on its own and especially with the optional PSX-R2 power supply."
  • Rene: "I experiment with an original pressing of Pink Floyd’s Dark Side Of The Moon, tracks like ‘On The Run’ and ‘Time’ are useful. The Cyrus is so pure and clear that although I’ve played this record many, many times I notice some small details I was not aware off before."
  • "This Cyrus proved to be a versatile product for vinyl lovers with one or more arm/cartridge combinations, it’s a pleasure to listen to and worthy of the Signature label."
  • "Ultimately this is such a good phono stage that you don’t need nor want to spend time comparing the effect of different loadings, you just want to play more vinyl."

  • Sound 'Absolute top class" Overall rating "Very good"
  • Price/ Performance: "Very good"
  • "The Cyrus Phono Signature delivers a real surprise - detailed, but with a gentle yet unyielding attitude, giving a vast open soundstage. Super comfortable, super flexible, super features. A prime phono pre-amp for serious cartridge fanatics who still like making use of the remote control. Criticism to the sound? Oh no, not even from me, the nit-picker."

CYRUS Phono Signature - Stereo (Germany) review
  • Michael Lang at Stereo Magazine Germany, recently reviewed Phono Signature:
  • Sound Rating: 91%, Overall "Excellent"
  • Price / performance: "Excellent"
  • "A lot of time elapsed since CYRUS in 1998 showed up with the aEQ7, the company's first discrete and serious phono stage. Peter Bartlett, mastermind of the English company, developed with the Signature a clever successor. But a "me too" product was not at issue, they wanted to create something outstanding, yet not give up the classic Cyrus design style".
  • "The outcome is an amplifier for vinyl use, which at the same time fascinates analogue enthusiastic dealers as well as experimental customers - thus the "Signature" offers connectivity and individual settings for four turntables (!). Each input can be allocated with an MM or MC cartridge; gain, impedance and capacitiy can be adjusted in several stages - and this even with a remote control. Not only that, the English offspring comes also with a balanced and an unbalanced output, so that it can be docked to any sound system configuration".
  • "Technically, Mr. Bartlett and his crew paid attention to extremely short signal paths as well as to anything else that you usually can find in a developer's treasure chest. So special relays are used right at the beginning of the signal input, just to avoid any interference noise getting close to the extremely weak cartridge signals. The power supply section is as far as possible away from the input section, and the toroidal transformer is custom made to Cyrus' special application requirements. So to say, this is a "Jack of all trades" phono stage. Sensationally equipped and sonically barely less gifted, it surely will find its fans! No doubt, the Signature has far more to offer than ample features!"

  • Phono Signature has received a fantastic review from Paul Rigby at Hi-Fi World. Awarding a full 5 globes Paul says:
  • "The Phono Signature digs deep to offer a host of detail while its balanced output adds finesse.'
  • Phono Signature was reviewed alone and then partnered with the PSX-R2. With the addition of the external power supply he says: 'First impression was of an immediate lowering of the noise floor which freed me to increase the gain. Bass now featured extra information and detail with each drum strike.'
  • 'The sound quality of the Phono Signature was immediate, detailed and offered welcome delicacy in balanced mode while the external power supply is an essential upgrade when funds allow.'

  • Helmut Rohrwild of HiFi & Records, Germany, reviewed Phono Signature:
  • "The Cyrus Phono Signature with its multiple connectivity and adjustment possibilities makes analogue dreams come true. Cyrus' Phono Signature always operates at a high quality level with paradigmatic accuracy. The ability to have four cartridge systems connected and to adjust each of them to its appropriate values, puts the Cyrus in a unique position. The impeccable finishing completes the picture. Its price is extremely low for what is offered, thus earning the Cyrus an emphatic and unrestricted recommendation. Have a listen, absolutely!"

  • In FIDELITY (Germany) No.26 Issue 4/2016, author Uwe Hecker reviewed Phono Signature:
  • " Made für's third millennium. The current vinyl boom sparked the English tradition manufacturer Cyrus Audio to reconsider its external phono preamp new. The result was a milestone. Once everything has been set, you can thus completely carefree look into the actual determination of Cyrus Phono Signature: hours surfing with him through the record collection and rediscover music sooner or explore new ones. That leaves virtually no acoustic recognize weakness of Cyrus, helps immensely. Voices are reproduced vividly and authentically, the spatial representation is broad and deep, individual melodies or orchestral parts can be targeted and easily investigate. Dynamic jumps are executed without warning, and the remarkable noise freedom lays in very quiet passages no Störnebel about the music."
  • " Not only complete in almost all respects amenities Cyrus Phono Signature, his flawless sound quality justify every euro you pay for it. It is certainly a groundbreaking phono stages for the third millennium and definitely what the English call a "Best Buy". Congratulations!"

  • Ansgar Hatscherat of HIFI-Stars, Germany, reviewed Phono Signature:
  • "In the basic version of the" Phono Signature "the handwriting of Cyrus was seen sonically always, the agile, rhythmic, self-contained play makes a lot of fun. After the extensive audio impressions with Phono Signature I was looking forward to the effect of the PSX-R2 power supply. It came, as it had to, and has been repeatedly verified elsewhere: the current makes the music! The PSX lifts the Phono Signature sonically me previously known phono precursors beyond and is completely for flyer in its class."

Product Overview

Technically the Phono Signature has been designed to exceed the expectations of serious vinyl audiophiles, particularly in areas such as; dynamic performance, accurate cartridge matching and flexibility of use. By adding IR remote control of cartridge matching we can for the first time ever, provide invaluable tonal control to rebalance imperfect discs.

Designed to appeal to the most advanced vinyl enthusiasts who enjoy multiple cartridges, turntables or arms, each of the four inputs can be accurately matched to the exact specification of the cartridge, and now, the acoustic preference of the user. Adjustment is provided for MC cartridges in gain, resistance and capacitance facilitating a huge 160 possible combinations. In addition a switchable warp filter is provided to maximise amplifier performance.

This state-of-the-art phono amplifier allows real time adjustment of capacitance, resistance, gain and more, thereby providing invaluable tonal adjustment from the listening position. The inclusion of warp filter and Cyrus system volume adjustment completes a suite of remote control functionality that provides unequalled user involvement with vinyl.
