I’ve been running Hypex based Kharma amps for a few years now.
They’ve been out to bakeoffs in the past and variously sounded good to pretty average. Really depends on the implementation as with any component in a hifi system. Sometimes it gels, sometimes it doesn’t.
What I can say is that I’ve been happy enough with them not to chase a change in my system and I’ve had some capable amps through, Dartzeel and Jeff Rowland for instance. They’ve been perfectly capable of highlighting changes in my system, be it the introduction of a £30k pre, tubes v ss or digital v analogue. I like what they deliver in my system, without doubt there will be those who’d listen and have a preference for a different presentation.
Don’t let a few comments from those who’d pronounce judgement because they’ve heard a class D amp in a system that didn’t work somewhere (probably from the back corner of the room) put you off. As with anything in this game you can only go by listening within the context of your own system
