If you can get them at a good price, the PS Audio's are pretty good. One of my amps had to go in for repair and my dealer lent me the PS Audios to use until they came back. I think they sound better than they're newer amps.
PS Audio Delta 250 or Electron Kinetic Eagle 7b
Have a line on a set of PS Audio Delta 250 mono blocks and a Electron Kinetics Eagle 7b amp? I currently have a set of Eagle 400 mono blocks that I will be sending in for some updates and wanted to purchase one of the amps mentioned above. Kinda hard as I'm not able to do a demo before hand. I have herd good things about both amps so I'm on the fence.
