Graham Slee Accesion MM inkl. PSU 1 Enigma Netzteil, MM Phonovorverstärker The Sound The impeccable sound of the Accession stereo phono stage preamp takes music from vinyl and sets it on a new higher pedestal – it's what all vinyl lovers will want to hear. Previously overlooked technology has been perfected to extract much more of what's hidden in the music on vinyl records. The resulting sound from the Accession hi-fi phono stage preamp is considerably closer to the music laid down at its recording. Keeping Interference Out The Accession goes further than ever in keeping interference out: it has a solid ground plane board; multiple layers of radio frequency filtering; high immunity design, and the V2 casework has stainless steel "gaskets" behind front and rear panels which seal against electromagnetic disturbances - they provide conductive shielding in contact with board grounds which anodised aluminium panels alone cannot do. The Features And Their Benefits The package of features the Accession phono preamp provides makes it really flexible allowing it to fulfill a number of roles.

Graham Slee Elevator EXP MC Step-up Trafo The Elevator EXP will give you hum-free sound, purer bass, greater definition and much more of your music. In the beginning you'd buy a step up transformer (S.U.T.) to be able to use a moving coil cartridge. But they hummed and did weird things to the bass. The Elevator EXP changes all that. The Elevator EXP is supplied with the PSU1 power supply, and a choice of voltages and power plugs. Make Your MM Stereo Phono Amp Do Moving Coil The Elevator EXP is designed to step-up the tiny moving coil signal to the moving magnet level of a hi-fi phono amp input. It Also Let's You Adjust To Taste Whereas some moving coil cartridges will happily give their best with 100 Ω loading, others can be quite particular. Rather than fiddling around with links or DIP switches, the Elevator EXP gives you all its loading options up front, right there on the front panel - making it easy to get your sound right. Suitable Cartridges Low output moving coil (MC) with output in the region of 0.15 - 0.8 mV (ref 1kHz at 5cm/sec) The Elevator EXP must always be used between cartridge and a moving magnet sensitivity input. It must never be used 'post EQ' - after the moving magnet phono preamp.

Graham Slee GRAM AMP 2 Special Edition, MM Phonovorverstärker So Good We Went One Better The "stonking" musical performance mentioned by Geoff Husband at TNT Audio magazine in 2001 just about said it all about the Gram Amp 2. The legendary value-for-money of the Gram Amp 2 was etched into audio history right there and then. However, to show this wasn't a fluke we went one step better and made our best-selling budget phono preamp: the Gram Amp 2 Special Edition. Supplied with a basic ("green energy") power supply with self adjusting voltage, and with power-pins fitted to suit your power outlet — you can upgrade by swapping over to PSU1 power as and when you're ready. Cartridge Partners The Special Edition will not be found lacking in the company of the best high output cartridges. But where budget dictates, less-costly cartridges like Audio Technica's AT95E will still let it produce a highly satisfying sound. The Gram Amp 2 Special Edition phono preamp won't stamp any "signature" on your music so you'll be able to hear all the qualities of your cartridge. It will be a lasting part of your hifi system, and won't be easily outdone by upgrades to the rest of your system.

Graham Slee Novo, Kopfhörerverstärker Discretely InspiredDiscrete? Surely we meant to say discreet?The Novo is both: it's discreetly small - a definite miniature in a world full of behemoths; and it's discrete because that's the circuitry it uses - discrete transistors.Discrete transistors? Yes, you heard right! Most budget headphone amplifiers let an op-amp do all the work. We wanted to show that we're capable of more than that.The result is a very capable headphone amplifier, so capable that headphone manufacturer Shure bought some and Sennheiser featured it in a promotional video driving its flagship headphone.You may never have heard of the Novo headphone amplifier before today, but now you have. It's definitely worth your consideration if you're after a budget headphone amp - a hi-fi amp for headphones! The little Novo is supplied with an outboard basic power supply which automatically adjusts to your electricity supply voltage, but it can be upgraded later on by swapping to the PSU1 power supply Technical Details Headphone impedance range: 16 to 600 Ohms preferred; 8 to 2,000 Ohms acceptable Power output (rms, both channels fully driven): 32 Ohms, 27mW/channel,  600 Ohms: 23mW/channel Distortion (THD plus noise, ref 1kHz): 0.02% Frequency response (-3dB)32 Ohms load: 27Hz - 35kHz; 600 Ohms load: 10Hz - 39kHz Output noise (20Hz-20kHz, CCIR quasi-peak): -84dB Input sensitivity (for specified power output): 32 Ohms: 250mV rms; 600 Ohms: 775mV rms Channel balance: better than 1dB, "9 to 3 o'clock" positions Crosstalk: Left to Right -57dB; Input to Input -68dB Mute: Signal off mute, non-shorting Output Stage: Bipolar class AB Supply voltage: 24V DC Size (approx.): W: 107 x H: 50 x D: 125 (mm) inc. controls

Graham Slee PSU1-Enigma, Netzteil Originally designed for the Accession MC and finding it brought an audible (in our opinion) improvement with the Majestic Pre/DAC, it has since also found favour with users of some of our other phono stages. Thanks to Kirchhoff's scientific current laws and the law of conservation of energy we can see current leaves from its origin somewhere in the power supply and has to get back to that origin. Signal current, no matter how well it is treated by the phono stage, must negotiate the inner workings of the power supply. Knowing that origin and how it gets back to it is crucial in understanding how best the micro-signal current returns to its origin with the least possible disturbance. The Enigma solution was to lower the dissipation factor, improving dielectric absorption (similar to PTFE and polypropylene) for greater frequency stability such that all frequencies of signal current are treated more equally. And additionally: fine tuning its Kelvin paths and giving it a new DC cord and lockable outlet. Dropping dissipation factor also increased ripple current handling by 35%, and when tried with the more current hungry Majestic Pre/DAC, a significant improvement to the solidity of the sound was evident.

Graham Slee REFLEX C inkl. PSU 1 Netzteil, MC Phonovorverstärker Faster - For Winning Results You buy a moving coil cartridge for high-performance — so team it with a performance phono preamp for winning results! The music you listen to should be your choice — your equipment shouldn't dictate your musical taste. That's the trap many fall into when "upgrading" to moving coil. If in doing so, you find it difficult to listen to your kind of music, read on, and find out why you need this high performance phono preamp. The Reflex C is supplied with the PSU1 power supply, and a choice of voltages and power plugs; 100 Ω or 1k Ω input impedances; and there is also an option to have a mono switch fitted. The Reflex C Gives You The Freedom To Choose The Reflex C uses low-noise video amplifiers which overcome the difficulties of input saturation and slew induced distortion. You can play the music you want! Throw the fastest tempo music at the Reflex C and you'll marvel at its pace. It captures all the subtleties of your music - all its detail - plus it projects a really convincing and articulate stereo image - and much less in the way of clicks and pops. The Reflex C is the answer to moving coil preamplification you've been waiting for. Suitable Cartridges The Reflex C is suited to low output moving coil (MC) with output in the region of 0.2 - 1.0 mV (ref 1kHz at 5cm/sec) Cartridges having lower outputs may be used if you accept the risk of hearing more hiss than you may be comfortable with. Your amplifier's volume control is intended to be set to give you the loudness you want and should be adjusted accordingly. With the lowest output cartridges you will need to turn the volume control higher than you would use with other sources such as a CD player.   Technische Daten Item Measurement Input and output connectors RCA/phono sockets, hard gold plated Input sensitivity range 0.2mV to 1.0mV (recommended) Output range (for above inputs) 252mV to 1,260mV Maximum input 3.9mV rms Maximum output 4.914V rms Gain 62dB (1,260) at 1kHz Input impedance 100 Ω or 1k Ω to order Output impedance (driving impedance) 1k Ohm (will drive 10k Ohms and above) Noise at output -62dB CCIR Quasi-peak 20Hz to 20kHz Distortion typically 0.02% RIAA accuracy < 0.5dB Frequency response 20Hz - 100kHz ("flat", corrected to RIAA) Channel balance 0.2dB Channel separation 60dB Power supply remotely powered using PSU1 linear power supply Size (approx.)

Graham Slee Solo SRGII, Kopfhörerverstärker All of the Solo's amplification is concentrated into its single stereo ouput - it doesn't compromise on sound like multiple outputs will. If you listen on your own it's the ideal headphone amp!ll of the Solo's amplification is concentrated into its single stereo ouput - it doesn't compromise on sound like multiple outputs will. If you listen on your own it's the ideal headphone amp!The Solo SRGII headphone amplifier is the refined version of the legendary "green" SoloPlus it offers an easy and simple upgrade path which involves swapping its outboard "green-energy" power supply to the PSU1.SRG stands for Studio Reference Green. SRGII is the MkII version. It's available "in green" with its energy saving basic power supply - or go straight for the upgrade and buy it with the PSU1 power supply. Delivering Wonderful Music Under Adverse ConditionsThe Solo's have a long history of delivering wonderful music going back to 2001 as borne out in numerous reviews over the years - often beating off stiff competition from more expensive headphone amps.The "green" Solo surfaced in 2007 as the first ever seriously hi-fi headphone amplifier to succesfully run off green energy otherwise known as switched-mode power.It had to be done because legislation on energy using products was about to become a legal requirement by 2010, and switched-mode power supplies have since become the de-facto source of outboard power for economy product variants such as the less-expensive Solo SRGII option.The problem earlier hi-fi products had was that switched-mode power has so much high-frequency distortion content, and as all amplifiers output what is essentially signal-modulated power, that distortion content ends up at your headphone diaphragms.The complex behaviour of such distortion content with headphone diaphragm earpieces, not forgetting the amplifier itself, simply throttles the sound.The "green" Solo, and now the Solo SRGII, overcame the problems switched-mode power caused, but went much further and the SRGII sound can fend off competition from more expensive headphone amplifiers using non switched-mode linear power. Headphone Impedance SensingThe Solo SRGII headphone amplifier has another trick up its sleeve, that being its headphone impedance sensing output.Some output impedance is essential because headphone cables are highly capacitive, and without output impedance, amplifier phase margin is seriously compromised.High impedance headphones with long cables (and there are plenty of them) can lead to phase margin reversal and that's why many solid-state amps don't work well with headphone impedances much greater than 30-40 Ω.Exactly how much output impedance can be tolerated before a headphone stops performing well, will depend on the impedance of the headphone being used - and we can never know what the customer is using.Headphones have impedance dips and peaks across their audible spectrum, needing more control at some frequencies more than others.Zero output impedance would be ideal, but screwing down the high frequency performance to preserve phase margin is no good for outright musical performance.Output impedance cannot therefore be a fixed value that suits all headphones. But, by sensing the headphone current, extra power can be delivered to the headphone to cover for impedance dips, and less power for impedance peaks - thus making for a smoother sound.The actual output resistance can be kept constant guarding phase margin whilst output impedance will appear to be changing to compensate.And that's basically how the Solo Studio Reference Green MkII achieves its really well-balanced sound regardless of headphone impedance.And importantly for the most sensitive headphones, it doesn't hiss!Technical Details Headphone impedance range: 16 to 600 Ohms preferred; 8 to 2,000 Ohms acceptable Power output (rms, both channels fully driven: 32 Ohms, 27mW/channel; 600 Ohms, 23mW/channel Distortion (THD plus noise, ref 1kHz): 0.02% Frequency response (-3dB): 32 Ohms load: 27Hz - 35kHz; 600 Ohms load: 10Hz - 39kHz Output noise (20Hz-20kHz, CCIR quasi-peak): -84dB Input sensitivity (for specified power output): 32 Ohms, 250mV rms; 600 Ohms, 775mV rms Channel balance: better than 1dB, "9 to 3 o'clock" positions Crosstalk: Left to Right -57dB; Input to Input -68dB Mute: Signal off mute, non-shorting Output Stage: Bipolar class AB Supply voltage: 24V DC Size (approx.): W: 107 x H: 50 x D: 185 (mm) inc. controls

Graham Slee Solo Ultra-Linear DE, Kopfhörerverstärker The Solo Ultra-Linear lifts the performance of any good music source and quality dynamic headphones.Graham Slee Solo headphone amplifiers are well-known for their great stereo imaging and musicality, and the Ultra-Linear Diamond Edition (DE) will give you effortless dynamics, a powerful but not boomy sound, and a valvey (tubey) smoothness with detailed clarity. The Solo Ultra-Linear is supplied with the PSU1 outboard power supply.And It's A Solid-State Headphone Amplifier!The Solo Ultra-Linear Diamond Edition (ULDE) headphone amplifier replicates tube amplification, but is solid-state to keep it's performance for all its long life.So what about tubes does it replicate? It replicates the most important difference between tubes and solid-state, that tubes give a flatter open-loop frequency response which extends into the mid frequencies, before negative feedback is applied. It means that when it's applied to keep distortion low, it is true 180° negative feedback, and it gives a wholesome sound which otherwise is sadly lacking in solid-state.We use our proprietary and well-guarded bandwidth extension technique we call Ultra-Linear which replicates this most desirable of tube characteristics.The Solo ULDE has a completely redesigned output stage and better noise performance than the earlier Solo UL, which means it will drive a much greater range of high performance over-ear dynamic headphones, and be hiss-free when used with in-ear monitors.Unlike tube amplifiers it works with all common headphone impedances, and its Z-Match impedance ranging volume control takes the place of gain switches, allowing amplifier gain to be fixed so it results in optimum musical performance.Generous phase and gain margins give it great high-frequency stability under all loading conditions. This coupled with its wide input latitude lets it effortlessly reproduce large musical transients with real clarity.Excellent power supply filtering and ultra-stable voltage regulation make its power so clean that it depicts the minutest of detail, the nuances - the shades of expression, so your music really communicates with you.It also results in superb stereo imaging with great separation between performers and instruments, dispensing a believable stereo sound stage.Technical Details Headphone impedance range: 8 to 2,000 Ohms / 16 to 600 Ohms preferred Power output (rms, both channels fully driven at 1% THD): 32 Ohms, 140mW/channel; 600 Ohms: 30mW/channel Input sensitivity (for specified power output into 32 Ohms)    511mV rms Input impedance: 37k Ohms at max volume; 50k Ohms at min volume Distortion (THD plus noise at 9 o'clock volume control setting (qtr power)): 10Hz-20kHz: better than 0.04%; 10Hz-1kHz: better than 0.02% Frequency response (±0,-3dB): 10Hz - 35kHz Output noise (22Hz-22kHz, quasi-peak/un-weighted): -95dB Channel balance: better than 1dB Crosstalk: Left to Right -56dB; Input to Input -68dB Input selector centre-off position: non-shorting; -38dB at max volume with 2V rms input (ref: 1kHz and 10kHz) Output Stage: Bipolar class AB Supply voltage: 24V DC unipolar Size (approx.): W: 107 x H: 50 x D: 185 (mm) inc. controls
