Talk to the tube guru ,Kevin Deal at Upscale Audio.I got a matched pair of Tungsram 6922 tubes for my Audible Illusions. M3A ,and it was equivalent to an upgrade.A Mullard tube should sound fine for now ,as it was what I had in my SFL-1 Sig. Happy listening!
Tube recommendation for SFL1
Thanks for those who recommended SFL1 for my Bryston 3BST amp with B&W CDM1SE and two Kimber 8TC biwired. Since I am new to Tube amp, could you also recommend good tubes for SFL1? How much do I expect spend on tubes and what are their lives in general? Thanks much. Danny.
