ACOUSTIC IMAGERY ATSAH NC500 Monoblock Amplifiers
The ATASH power amplifier is a Class D design and is based on NCore® technology from Hypex. NCore® is the name given to the first significant step up in power amplifier performance in a decade. https://www.hypex.nl/p/technology/ncore
Building on the strong heritage of the UcD design of Class D amplifiers, NCore® takes the things UcD does well and does them ten times better.
Coupled with a dedicated switch mode power supply made specifically to work with the Class D design, this amplifier not only nudges at the performance of the best linear amplifiers, but surpasses them in every aspect of sound quality.
I went to the tube side but these amps beat out any class A amp I have heard or owned regardless of price.
