Orchard's class d ganfet amp is the real deal- read the review in audio express. It uses post filter feedback and has a frequency response that is load invariant, meaning it doesn't change character with a speaker's varying impedance. Most well designed class d amps will be load invariant. Not so for many of those using the gan module used in the peachtree and lsa gan amps. Be careful with those as they might sound fine with speakers with a tame impedance equal to the design point but anything that varies wildly and doesn't sit nicely at the design point impedance will change character.
The best performing class d is currently coming from Hypex and Purifi. VTV, Buckeye, March, and others are selling amps at unbelievable pricing using these amp modules.
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.
