My Primare I32 is it for me. They are up to model I35 now with a bunch of add-ons like built in DAC, and network player modules that boost the price to $4,500 minimum. If you don't need 150 watts the I25 lists for $3,299 new and delivers 100 watts. These are in the Class D category but use proprietary power modules that operate on a unique principle. I find the sound to be crystal clear, but very natural.
There are 3 Primare integrateds for sale on this site right now ranging from $3,00 to $800. https://www.audiogon.com/brands/primare-systems
The Primare I32 was compared favorably to the Belles Aria in several reviews back in the day (the 132 come out slightly on top) so that would be a good bet, also.
