I use power conditioner, but it's really more about surge protection since we have more than our fair share of power outages. At this point I've chosen security over sound quality though it still sounds pretty great to my ears. I didn't use the power conditioner when I had a Krell S-300i because it exceeded the capacity of the power conditioner.
Power conditions for Integrated Amps
Anyone using a power conditioner for an integrated? I keep hearing to plug your amp direct into a wall, and use a conditioners for the rest of your equipment. So, what do you use for an integrated? I'd like to hear from actual integrated amp owners mostly. Others are welcomed to chime in of course!
