Advice re PC for Plinius amp

thanks for the ideas. Just to be clear (as I clearly was not in my initial post) the hum is not at the amp, it is back thru the system and it gets much louder when I move the amp to class A mode via its selector switch,

I am intrigued by Horseface's suggestion to move to SE IC's - I currently use balanced transparent cable IC's (15' length). I will try SE IC's.

Hello Steve,

I owned Plinius SA-102 and I am familiar with its hum. I will confirm Stereophile writer's observation that when I installed "cheaper" and "cheaper" (thinner and thinner) power cords the hum went down.

I wonder how SA-250 handles your Apogees Scintilla and is it better (for you, of course) musically then Spectron amp you owned?

Incidently, they developed new high current power cord (about $500) but I did not have a chance to try it

Good Luck
Rafael

sorry for not being helpful, i have an old plinius 8200mk2 intergrated and the hum you were describing is audible through my speakers as well, however im not so bothered because it's only there when it's on standby mode.
No issue while playing music.
Me too is looking to upgrade my siltech PC the back of my Plinius, Im hoping to take it to a higher level in terms of dynamics and timbre with cheaper cable, since the siltech are already very smooth and natural sounding cable, i feel that Plinius could benefit from something dynamic. Im interested in knowing what PC everyone uses for their Plinius amp. I'm thinking of dnm reson, Oyaide, lessloss, or MIT.

I own a Plinius SA-100 M3. I am using a Purenote Alluvion power cord. Zero hum issues with 94 dB sensitivity speakers.
