I'm in the Hypex and Purifi camp, Bruno Putzeys is a wizard. I have the March Audio P502 and it's been a high wattage wonder in driving my inefficient Maggies and Vandies. Wonderful detail and clarity, and driving bass to get the toes tapping and the emotions rolling. Dead silent, no noise whatsoever. March has gone all Purifi, can't go wrong there, currently I would get the P422 stereo power amp. Love the compact chassis, build quality and efficiency. IME separates are nicer than an integrated, just got the Topping Pre90 not too long ago and that's all the pre you'll ever need, wonderful relay-based volume control, a bargain, and the drive of all balanced connections is great. Alternatives to March are Audiophonics and VTV, who offer Hypex and Purifi based amps.
New Class D amplifiers
Hello. I'm very interested in getting your opinion on the newer Class D amplifiers. There has been a couple of very positive reviews (by Guttenberg) of the Bel Canto C6i and NAD M23. These, and perhaps some others are offering new technology that significantly lower the class D noise level and other drawbacks.
I currently use a Class A amp, Pass Labs INT-25 (with Dynaudio Heritage Special speakers) which has a wonderful sound. But I am transitioning to another location, and due to using Roon primarily I find that this system stays on most of the day. Due to heat and power usage of Class A amplifiers, I'm interested in translating to Class D if I find something comparable.
