I absolutely plug 100% of my audio gear into Furman with LiFT and SMP protection. in particularly noisy environments (apartments) I miss them when they are not in place. I use a Luxman 507ux BTW.
I wrote about this here:
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!
