Are the current Purifi based stereo amps and monoblocks considered the best in terms of measurements, power, heat, weight, sound and cost/value vs class A and AB models like Bryston and the like?
For example, 2 x Bryston 7b3 monoblocks are about $16k, weigh a ton and generate a lot more heat, with larger footprint.
Purifi amps like those from Apollon, BoXem, NAD, March and others cost just a fraction of that, even for monoblocks. They have the power, current and damping factor to drive and control even demanding speakers, run a lot cooler, have a smaller footprint, are lighter, etc.
So, I am wondering the following:
1. Is class D basically now good enough to make good, pricier, class A and AB stuff less relevant in 2023?
2. If Purifi is still popular and considered the way to go, which maker is currently considered the best right now from a build quality, reliability, parts and power supply quality, and engineering perspective?
