time for amp upgrade

Of the list you mentioned my first choice would be for the Pass Labs. I have owned a couple of Krell amps (FPB 200; FPB 700cx) which are very good amps. I just like what Pass is doing right now, better than what Krell is building.

The new generation Pass Labs amps go back to the minimal gain stage circuitry of earlier amps, but with the higher power of the later models. The earlier amps were praised for their purity. The newer amps were roundly praised for their power and dynamics. The latest amps have the best of both worlds.

Don't take anyone's word for it, find out for yourself, it's your money and your ears...

Everything I don't like sucks!

Dont forget the Ayre V-5x. It would drive those speakers lovingly!

I like Nrchy statement," Don't take anyone's word", but use your own ear's with your gear in a home audtion. I went through a audtion process that included ML, Boulder, VTL, Antique Labs, and finally replaced my Pass Labs Aleph 1's with an Edge NL-10 for a couple of years with great sonic pleasure. Untill, I heard the Pass Labs X-350.5 which is the most gratifying amp I have ever had in my system. I wrote a reveiw here on the GON on the 350.5 which might be helpful to you. It's a great amp and might be a great fit with your gear and your personnal taste. Good luck, start audtioning, and tell us about what your ear's tell you.

I would second the Edge Electronics amp lineup, the NL or the G series. I have not heard the Pass Labs 350.5 so I am not sure what I maybe missing.

With a sensitivity of 89 dB, the more power you can afford the better. I am running planars with similar sensitivity and I tried to get the most power I could afford.

I second Artg nomination of the Ayre,most impressive,Bob
