I own this player am using some Mullards that I bought from Upscale Audio and am very pleased. The Mullards will smooth out the highs and are great in the mids.
Lector 7T and tube rolling
I'v got this nice CD player, but would like to have even smoother highs. It has originally CVC Chelmer valves (12AT7) and I wonder if old Mullards, RCA, Siemens or other NOS would change this?
Is it important to have NOS from the 60's or is tubes from the 80's almost as good?
Thanks!
