What about 'worst case scenario' of 2 amps using the SAME schematic for build. The first amp uses high MTBF semiconductors, ample heat sinking and does a 100 hour factory burn-in at from 20% to 80% power THAN readjusts bias and PS offset. They also use REAL glass Expoxy boards, all 1% or better film resistors and 5% caps, where available.
AMP #2 just buys 'whatever', uses pressed cardboard circuit boards and has a 15% in-line rejection rate on finished goods.
Who are you going to buy? If I like the amp, I'll spend whatever it takes to GET it and skip the stuff which may SOUND alike, but for how long?
Too much is never enough
