Moving Coil Step-Up Amplifier

Match low output moving coil, and low output moving iron cartridges, to the input sensitivity of our moving magnet phono preamp stages and get superb results.


7 Good Reasons to Choose a Graham Slee Phono Preamp

Phono Preamp Patent
  • 20+ years of making some of the best sounding phono preamps in the world
  • The only manufacturer granted a phono preamp patent in recent times
  • Graham Slee phono stage preamps are known world wide
  • Highly rated by respected reviewers
  • Prove it for yourself - backed by an international loaner program
  • More than 60 dealers world-wide
  • Every piece hand built and tested to order by our experienced craftsmen

If a job's worth doing it's worth doing right, and the Graham Slee team here at HiFi System Components will make you a phono preamp you can be proud of and enjoy your music with year after year.

A Graham Slee phono preamp is special as any owner will tell you. And Graham Slee insisted each preamp be made to order by his own team in England - yes, even the budget Gram Amp 2 - so you can treasure the sonic delights of a true thoroughbred phono preamp design.

(These are not aggressively marketed "mass produced over there" phono preamps masquerading as being hand-crafted by a quaint cottage industry, as many are)

Some thoughts on the phono preamp by Graham Slee:

"For me, a best phono preamp is about getting the level of musical performance that pulls the right strings of your emotions, and it doesn't matter at all what type of music that is.

Classical Music

Some suggest hi-fi is all about classical music because classical music demonstrates what's good about hi-fi. Hang on a minute! Surely this isn't a hi-fi demo? I thought we listened to music for enjoyment? If your cup of tea is classical then great, but listen to it for the music, not the equipment (as so many seem to do).

What about other musical genres? Jazz and theatrical musicals are usually acceptable as hi-fi genres, but what about the rest? Traditionally they've been disregarded probably because our parents told us rock and pop was just compressed noise? The thing is music is music, and no matter what the genre, if your music makes you happy then hearing it in all its glory might be something you'd want to do? If it's on vinyl then you'd expect the best phono preamp to do it justice.

But you only need to visit a hi-fi show to realise the music is carefully chosen to show off the equipment as impressively as the exhibitor can, and so often it's with classical music. OK, you might get "Hotel California" from Hell Freezes Over demonstrating the thumping bass, or "Get Your Filthy Hands Off My Desert" from Pink Floyd's Final Cut to demonstrate the explosive dynamic range, but what about your music?

Rock Music

The age demographic of hi-fi customers has shrunk and now mainly encompasses the older generations (it no longer grabs the attention of the more youthful except perhaps a small minority and now mainly includes age groups 50 - 90), but when young these older generations were more likely to enjoy rock, pop, reggae, disco, psychedelic, new wave etc. With hi-fi still tied to classical music as it is, will "the best phono preamp" do justice to the favourites listed above? I know some publicly say they do while harbouring the desire for better. Only you can answer for yourself.

I, being one of the older generations, listen to a wide variety of music, and admit classical is not my main source of listening pleasure. Therefore I design phono preamps to communicate the full breadth of my listening material as enjoyably as I can make myself to do.

It's quite incredible how much further you can get into your music given the right phono preamp, and by right I mean a phono preamp which takes its input straight from the pick-up cartridge. Turntables with built-in phono stages will not do it, and even though they might have a bypass switch it never switches out the input impedance so ruins the performance of an outboard phono preamp.

Bluetooth Record Player

Even worse are USB phono preamps (and any turntable with a digital interface). The clock frequency modulates the tiny audio signal from the cartridge, and although the clock frequency is way beyond our hearing range, the distortions it causes isn't, and you won't hear the hidden depths of your music.

Tube phono preamps have gained a huge following but that's often in ignorance. There is absolutely no way a tube phono preamp can be accurate enough to reproduce modern (late 60's onwards) vinyl properly.

Nearly all these tube phono preamps are based on an RCA design (below) produced in 1953 for the "new" RIAA standard. Standards at the time allowed +/-2dB deviation (PDFs: 1. AES Standard Playback Curve and 2. Evolution of a Recording Curve, p19, Audio Engineering July 1953) with preamps intended to be used with tone controls to correct for the inconsistencies of valve circuitry and provide the required tone (tuned by ear?). But in hi-fi tone controls are frowned upon (a nice bit of hypocrisy?), so the chances of obtaining the correct tonal balance from your records using a tube phono preamp are very slim.

Tube Phono Preamp Schematic

If you think that's bad you should take a look at low voltage tube phono preamps. These only work by allowing grid current to flow, which was an absolute sin in the valve era as it introduces gross-distortion: not just the "warmth" of second harmonics, but the objectionable odd harmonics too!

It should be obvious that valves are being used this way for one reason and one alone: it is a gold rush as can be seen by the sheer number of "manufacturers" milking it for all they can make.

I'm sure the foregoing will cause valve enthusiasts everywhere to feel aggravated, but I'm only stating the obvious. I quite like valves in tube guitar amps where they can be used artistically to create wonderful music, but I don't want them altering the sound when I play well-recorded albums!

I'm often asked why I haven't designed an MM/MC phono stage. To do that properly requires two differing phono input technologies because moving magnet cartridges and moving coil cartridges have different characteristics. This fact doesn't seem to stop others doing so. Many of these MM/MC phono stages use the same input stage but switch gain and load impedance to suit, except the preamplification technique isn't optimised for both types of cartridge, and can never be. Some are optimised for MM, but mainly you'll find they're optimised for MC (moving coil sales obviously make dealers more money), so if you've bought a very good moving magnet cartridge you're not going to get much value out of it.

 
The wheel came off!The wheel came off! (this is what usually happens when trying to do too much)

To design a first rate phono preamp is not an easy task. A first rate MM/MC phono stage is even harder to achieve. MM cartridges are high impedance and need a high impedance phono input, and high impedance phono inputs are too noisy for the low output of MC cartridges. MM and MC phono inputs can be put in the same box but that makes them more expensive than the compromised unoptimised types which share the same circuit, and which are more prevalent than they ought to be. In fact, some of the unoptimised types are sold for much more money than they are really worth.

A more economical way is to buy what you actually need. Our MM and MC phono preamp stages are optimised to give the best results for each particular type of cartridge. You could pay as much as £3,000 for a high end all-in-one phono preamp stage only to find it does half the job. Or you could spend a little less in total buying one of each knowing each one is optimised for the best results."
