The gain is not as high, in the other stages(compared to phono related) of your preamp, but noisy/microphonic tubes will still be audible. Upscale's graded tubes are tested for triode balance, as well as noise/microphony, which will also improve channel balance/imaging, in the SP-16. Everything hinges on how much you value performance.
? Tube Replacement Question ?
As a novice in the world of vacuum tubes, I have a couple of basic questions. I have a Audio Research SP16 tube preamp I purchased new in January 2008 & use on a daily basis. The tubes have never been replaced.
(1) When is it prudent to replace the tubes?
(2) Will sound quality deteriorate with age?
(3) Are there advantages of replacing the tubes with aftermarket alternatives vs. OEM tubes?
Thank you kindly for your help.
