As far as Class D, I did directly compare the Spectron Musician III Mk.2 with all upgrades to the Sanders and found that it sounded fairly similar. The Spectron may have edged out the Sanders when connected with balanced connections, but I just couldn’t pull the trigger because of some strange interference issues that I couldn’t eliminate. The Sanders seemed a little more natural, and the Spectron seemed a little better in vocals.
However, assuming that both amps function fine, I’d probably recommend the Spectron just because it’s usually cheaper than the Magtech on the used market by $500+.
