Subjective vs Objective? Audible differences in hifi

Let me begin by agreeing with MikeC: good amps exhibit only minor audible differences. This is not a magic technology.
Speaking of Hypex, those new Kii speakers sure look interesting.
ATI makes truly excellent amps IMO (the relay-free protection system is tops), but these are fair comments. A few years ago, ATI's factory outlet had significantly lower prices & was a good choice for people who value modular build & 7-year warranties from a USA factory.MikeC wrote:I would never use the ATI amps. Too big, too ugly, too inefficient.
THAT's the project I'm interested in! Strikes me as more power than I'd ever need, but headroom for EQ makes sense with active crossovers, etc.MikeC wrote:I'm working on putting together an 8-ch am using 8 class-D Hypex and Connex amp modules with SMPS PSUs. They all have the same voltage gain, which is nice. Roughly 70W each for the tweets and high mids, 250W for the lower mids and 400W for the bass. So about 800W per side, 1600W total. The whole thing, with power supply modules, will cost under $1000, and fit in a dual side heatsink case less than 4" tall, 17" x 15". Efficiency is over 90%.
