New tubes for SFL-1 / SFS40
Hello,
I'm thinking of replacing some tubes for both my amp / preamp. Currently, the system doesn't sound "tubey."
I heard the nature of SFL-1 isn't very tubey...but I am
hoping that replacing some tubes on both pre/poweramp will
give me the "tubey" sound that I'm looking for.
Please give me some suggestions on the tubes.
Thank you very much!
Sean
