Does anyone have or used the Edge NL-10

I'm currently using an Edge NL-10 with Revel Salon speakers.
I've been very happy with the amplifier. It sounds incredible, very neutral sounding without typical solid state artifacts. It is a match made in heaven with my Salons which need power to sound their best. I've had it a little over a year and it has been completely reliable. It takes about 200 hrs to truly start to sound its best, and kept improving till I had 500 hrs on it. It is very sensitive to power cords since it is a very high current amp. The best cord I've used on it is the Harmonix X-DC Studio Master (added an extra 1/2 octave of bass to my system with the blackest background and still was very neutral sounding, ie. no high frequency roll-off). I've tried all of the big name cords on it!

The M-Ls and the Pass are a good combo. You might consider passively biamping the speakers. I too have the Odysseys and it made a very positive difference when I added the second Rowland amp.

If I were you, I would try some power cords first before upgrading the amp, or try both to see what makes the bigger difference in your system. LOL.
