RE: triode wired KT88

Listen to TRE.

Think of it this way-- a PP circuit is a processor-- it forces
reduction of signals and distortions found in the Common Mode--
including musical artifacts that are in the common mode (not all parts of music are). Since most of audio here in the States uses 60 HZ A.C. power,
PP and/or balanced circuitry is commonly used to PARTIALLY SHORT OUT
A.C. interference that is Common to both sides of a signal--
hence, the "Common Mode" moniker. Of course, some artifacts
of music are also found in the Common Mode, so they also get reduced/processed by a PP and/or balanced circuit.

Single-Ended cannot do this. The only thing it can do is amplify
ALL of the signal, which includes both the negative and positive of it.

That is why S.E. sounds more real. It hasn't been processed.

S.E., of course, is much more expensive and harder to build right.

If you don't do a lot of exotic engineering and spend some real
money on S.E., you will prefer the easy to get extra bandwidth and power
with PP-- and that is why most users have PP amplifiers.

They're NOT getting ultimate musical expression with PP. What they
have is easy to get POWER and lots of EASY TO GET bandwidth.

Since Common-Mode reduction is inherent to PP topology, low hum
levels and low distortion measurements are EASY TO GET-- allowing
MUCH cheaper parts and engineering costs and MORE power.

S.E. has only one saving grace: it can actually reproduce music the
way it was recorded.

No PP amp has ever done that-- or ever will.
