Which class d amp?

I have Nuforce 9 V2 SE which I like very much with a tubed preamp and VS VR 4 SR speakers. You are going to have to take all opinion with a grain of salt. This class amps have evolved so quickly that only comments about the latest models will represent the brand accurately. Also the amps are highly sensitive to vibration control, power cords and source, so these things will effect the opinions that you receive - but the newest renditions are worth checking out.

There is yet another entrant coming, this one by Axiom Audio, the A-1400-2 which to my ears is much better sounding than the Bel Canto ice power modules. I was lucky to get an early unit. Several differences contributing to the sound are the lack of feedback circuitry, massive 140,000mf capacitors, huge 1600kva transformer and dynamic allocation of power to each channel. Its been tested at over 1000wpc using a 15 amp circuit and much higher with a 20 amp line.

If you include used amps, I have and recommend the ARC 150.2. Similar to Jakeman's post about the Axiom Audio, the ARC has a huge power supply, and was only discontinued by ARC in 2006 when Tripath, who made the switching chip, went bankrupt. I find it interesting that all the published reviewers of the 150.2 loved it (one, reviewing the "big brother" 300.2 actually bought it for himself after reviewing it), while some "unpublished" (i.e. not the authors of the reviews) critiqued the high end. When I last looked there was at least one available in the SS amps "for sale" listing.

Colin heres another recommendation for Nuforce Ref series amps. Using the SE V2 version with the utmost of musical enjoyment. They will drive my Tyler Linbrook System with ease. Run cool, and sound very clear and clean. You will be hearing as mentioned above many different ideas from our audiogon group as this is a popularity question you asked.

Nuforce offers a in home trial and before you buy. I would audition in your home before you buy anything if possible. Good luck in you quest.
