[Amps] LK-500-NTC v. SB-220 v. Clipperrton L

[CAA357 at aol.com]

Opinions wanted: 
 
Today I adopted yet another amplifier in my small formidable shack and that 
 is really two too many hi hi. I want to lighten my load however, I  am 
trying to decide which amplifier to keep. 
 
Give the selection between: SB-220 with all of the Harbach upgrades,  
Clipperton L with new power supply board and recently acquired AMP-Supply  
LK500-NTC looks mint however not yet tested.  How would you rate each of  these 
amps and which one would you keep? 
 
I look forward to your input.
