Well then you need one of these Paul! :)

It's amazing to see matched pairs of 5U4 rectifier tubes selling for twice the 
price of an unmatched pair.  Or, $1K+ AC line cords marketed as a design 
derived from a DNA double-helix when home AC wiring between the receptacle and 
service panel contains common Romex and builder-grade receptacles, some of 
which are shared with other receptacles on a common branch circuit.  But 
somehow, none of that matters with the expensive line cord.

I recently saw several beat-up Gates Sta-Level compressors sell in excess of 
USD $3K each.  If any of you spent time in broadcast engineering, you know what 
these are.  We junked them decades ago but now they're the Holy Grail of audio 

I pay no attention to the tube v. solid-state debates and how colorful adjectives are 
used to describe an audio experience.  If there's some attribute that can’t be 
measured, I consider it non-existent and a figment of one's imagination.

Of all the audio amp parameters I deem important, it's the damping factor.  
Interestingly, few vacuum tube amps offer high damping factor owing to the ESR of 
transformer secondaries.  Many audio systems can be substantially improved by choosing 
an amp with a high damping factor.  Combine it with big copper conductor size Romex 
for speaker cabling and be done with it.  We don’t need expensive deoxygenation 
nor hyper-stranding to improve skin effect.

FWIW, my home amps are 1970s vintage Marantz.  They offer good performance, 
have a high damping factor, and are still easy to repair.
