Hi Efficiency system with low power SET and Push-Pull amps
I also have a bunch of EL84 PP amps ( Scott 222C/Fisher SA-16/Heathkit SA-2/Pilot SA-240/Pilot SM245/Pilot SA-232/Heathkit AA-151) and 7591 amps ( Heathkit aa-100/Eico ST-40) and EL84 SET and Sun Audio 2A3
and Dynaco ST-70 ran on this system as well.
After playing around with over hundreds of different cables, I then decided to make my own which works out just great.
The commercial cables like Stealth Audio and NBS were my best experience.
As far as power cord goes, the DIY cables can be really great.
