Gram Amp Communicator

Produsent: Graham Slee / GSP Audio

Pris: 2590


  • A high-end phono preamp design stripped-down to meet a budget
  • Suits high output moving magnet cartridges
  • Output connects to a 'line' or 'aux' amplifier input
  • Energy saving external power supply - self-adjusts to your mains/line voltage
  • Take it to another level of performance by using our PSU1 power supply
  • Designed to sound good when left on full-time
  • Good choice for doing vinyl "rips"

Timing is excellent, listening to Four Tet the rolling rhythm pulls us in to the track and the level of detail keeps us hooked, revealing intricacies we might not have heard before. It’s fast, organised and dynamic, too... Low on frills, high on quality, Graham Slee's aptly-named Communicator comes highly recommended.

One of the most astonishing-sounding albums I pulled out was the 1976 duet between jazz/world fusion group Oregon and jazz drummer Elvin Jones, Together. All acoustic, this album really showed Jones’ abilities, both as a swinging player and as an octopus-like polyrhythmic God. The record really shows the Gram Amp 2’s precise timing, its effortless handling of fulsome bass, its sheer musicality, and that fabulous soundstage for which it is already justly famous.

The GramAmp 2 was something else... What I didn't expect was for it to soundstage like a four-figure pre. This is the hardest thing for a phono stage to do. For it to come off the stage it must faithfully preserve the information on the disc, including keeping a firm grip on phase. The Gram 2 was fully a match for the Audion in this respect. Swapping to the Korato pre, which I strongly suspect is even better than the Audion, the Korato held on to a small lead in width and gave a slightly deeper soundstage. But though the difference was noticeable in an A/B I'm not sure I could have identified which was playing if I just walked into the room. And the Gram 2 gave nothing away in detail. It just lacked a little of the power and glory of the 'hi-end' stages, but at a tiny fraction of the cost this was a stonking performance.

After now 2 weeks of running in, the phono stage is getting better and better. It does control my speaker with a real strong hand, that my previous valve chinese was truly unable to do. I am so happy with it, really delighted. Best Value for Money! For once it gives the warming feeling that I could actually stop swapping boxes frantically every 6 months, and sit down and enjoy the MUSIC! Isn't it what it's all about?
