I know there are strong opinions about class D amps and if you have a strong bias against them, I might as well shut up right now :). However if you don’t, there are a number of class D offerings featuring Hypex and Purifi modules as well as ICEpower amps by OEM manufacturers. While many will poo-poo their sonic signature or perhaps the lack thereof, class D has truly arrived. Their advantages over other more traditional architecture is well documented and quite valid. I just recently got a VTV amplifier (assembled in Ohio) featuring the Hypex NC502 module that is one of the cleanest I have ever heard. Neutral, powerful, cool running and 350-ish clean watts into 6 ohms. Physically attractive in a minimalist kind of way and 759 bucks delivered. Hard to argue with roughly $1/watt of quality amplification. This could save you a ton of money over some choices you could make and you get a 30 day trial period. If you don’t like it send it back for a refund. Warren was great to deal with and answered my questions prior to purchase. No, I am not being compensated for the recommendation. Its based entirely on my own satisfaction with what I got for my money.
