Sounds like you put in some micro-phonic tubes. Did you do your due diligence before purchase, i.e. read up on the sonic qualities as well as mechanical issues. It's not hard to avoid micro-phonic tubes. Some folks also use rubber tube rings to quiet their tubes. FWIW.
Preamp upgrade
Hi all,
I'm considering changing from a tube pre to a solid state, partly because of the maintenance but also I want to try something different, my budget is $1200. I've also noticed an oscillating hum in the left channel, so I'm guessing a tube's going bad, so there's another reason. I'm looking at a Parasound P5 & McIntosh D100 which are listed on Audiogon, I'm looking for a little direction. Thanks in advance
My setup:
VTL 2.5 preamp
McIntosh MC275 amp
Sonus Faber Olympica I speakers
Auralic Aries streamer
Auralic Altair DAC
Clear Audio Concept turntable
Nordost cables/interconnects
