Alpha Nirvana 39w 8ohm Class A Amp

Maybe “degrade” is too aggressive of a description.
Having built a few amps, the dual mono power supply builds have the quietest background and slightly better stereo imaging in my subjective opinion.
You can build a Fantastic AN with a single supply! But, if you have the extra $$$ and chassis space to fit the dual supply it’s something to think about.
Or….
Initially build with a single supply keeping in mind the thought of “upgrading” later to dual mono supply.
