What is everyone using for the preamp tube and also down the line. Looking for articulate bass extended highs and sweet mids. Stock jj's are OK but I think I can do better.
preamp spot on the cm sounds best with anything amperex or made by amperex. mske sure it has been screened for low noise. transparent, dynamic, clean, refined and colorful.
i had the CM ii for several years and literally tried them all.
12AU7 matched Mullards from Andy's Tube Services here. I been meaning to call him and maybe try something new but the Mullards been sounding good for years.
Never had that amp but did own Rogue RP-1 and RP-5 with ST-100.
I liked gold lion in the amp in 12au7 and 12ax7.
For the preamp the best tubes I tried were Brimar CV4003 from Upscale.
I also tried rca clear top from Vintage Tube Services (Andy) and found them a bit too hot up top in the treble.
Gold Lion proved to be good again in the preamp as well as amp.
Didn’t care for new production Mullards and Tung-Sol.
