Elevator EXP step-up preamplifier

  • Moving coil step-up preamplifier to drive your MM phono stage
  • Electronic equivalent of a step-up transformer (SUT)
  • Seven different preset cartridge load impedances at your fingertips
  • Tube like extended open-loop frequency response from our Ultra-Linear "toolbox"
  • Inherent reduced vinyl click and pop characteristic
  • Rock steady sound stage and "3D" performance
  • Solid-state reliability

...the Slee provides better and more natural dynamics. The leading edges of notes are sharper, crisper and more 'real'... the Slee provides better focus along with a deeper and wider soundstage. Though some may say the sound is more 'clinical' than a step up, I'd term it as more transparent. On the best recordings, you really do get the sense of 'being there'. Once you experience this sense, it is unmistakable and something that follows you around to every system you will ever experience."

OK I'm going to nail my colours to the mast... Lucio has banned us from saying "best I've ever heard" "never heard anything as good" etc as it begs the question "compared to what?" and is often meaningless hype. But here I've listed the runners and riders, added the caveat "in my system and room" and finally "to my ears", so here goes. The Era Gold + Elevator EXP is the best phono combination for MC's I've ever heard - period...

...you obviously will need a step up transformer or head amp of some sort. I've got an old Signet MK12T (Audio Technica) that I use on occasion. It sounds fairly decent and is supposed to have some cool iron in it. In this case after flipping back and forth between it and my Graham Slee Elevator, the choice was more than obvious. The Slee it was.

Once the Elevator EXP and MC Denon DL103R were connected, I immediately noticed a significant increase in the soundstage, both in width and height and the imaging become more detailed and precise with instrument positioning being very well defined, I also noticed a greater depth and clarity to the music, there was a definite improvement all round to the SQ I was now hearing. My SGR CX3B speakers are extremely resolving and I can say that with the addition of both the Slee Elevator EXP and the Denon DL 103R cartridge, the detail and imaging I'm hearing now is just brilliant.

Hi I'm new to this forum my name is Doug. I have been using the Reflex M and the Elevator EXP for over a year and just love the sound. The wife and I tried many differant phono stages before we tried the Grahm Slee.A little backround we have Martin Logan Vantage speakers Simaudio W5.3 power amp McIntosh C2200 tubed pre amp Pro-Jects 10.1 turntable withe Benz micro SLR Gullwing cart and Cardas Clear and Golden ref cables. Just last week we brought in a friends McIntosh C2300 tubed pre amp with MC phono stage. Well we unpluged the C2200 and the Grahm Slee phono stage and gave it a listen.We played it for a few hours to get a fell for the sound. We then went back to my set up and WOW what a differance. The Grahm Slee sounded so much better the highs were so much better and the bass was well just like we turned up the volume.Sowhat I guess I'm trying to say is we love the sound we are getting from our Grahm Slee phono pre amps Cheers Doug

The Exp is indeed a fine headamp, Keith could tell you that I was indecisive for many months before replacing my SUT with one, but I have never regretted the extra cost, which it has repaid many times over.

The Elevator EXP step-up preamplifier preamplifies the signal from a conventional output moving coil phono cartridge to moving magnet cartridge sensitivity. The signal is then fed to a moving magnet phono stage. Unlike a step up transformer hum cannot be induced into it, and it's far more linear making for a tighter bass response.

It's the electronic equivalent of a moving coil step up transformer (SUT). However, a step up transformer easily picks up hum and electrical disturbances — it also consumes some of the delicate signal current to magnetize its core. Because the bass output of an MC cartridge is much less than the mids and highs, the magnetising current losses are not very linear and that makes transformer design difficult — it's never going to perform at its best.

Enter the electronic solution - the Elevator EXP. It uses a technique from our Ultra-Linear "toolbox" which extends open-loop frequency response, something that's usually only available with tube amplification, but tubes can't do such low level signals. It's hardly surprising that it does "the tube sound", but without all the problems you get with tubes — it's an excellent addition to any tube phono preamp when you want to use a low output moving coil.

But use the Elevator EXP with one of our great moving magnet phono stages and you're in for a treat! We recommend you use it with our Reflex M, Revelation M or Era Gold V phono stages — and so do a number of reviewers.

The Elevator EXP also features 7 different preset cartridge load impedances easily selected on the front panel.
