[QUOTE="hispls, post: 8399782, member: 614752"] All Zed amps forever have used regulated power supply. Stephen believes it's the best sounding/best method. After 35+ years or so designing amps I suspect he's a believer. He has been designing a few amps for some other companies lately (Focal for one and another old-name brand...can't recall which) and I'm not sure if they use regulated, though I expect Focal does anyway. They have some VERY nice and unique features. Consider pretty much every amp is a constant voltage source (or attempts to be) yes, they should all double power as you half impedance... making the same voltage into any impedance (to the point where they become unstable and blow up of course). So one that cannot deliver more current at the same voltage is being limited.... obviously by design, and it's a great marketing tool, but we can assume that the power supply they put in them would not deliver double power at 2 ohms without failing.
