In Reply to: Tube rolling preamp or power amp gain tubes, which ones (or both)? posted by 2121@comcast.net on January 16, 2017 at 04:46:39:
Terrific insights and advice that should help guide me as I continue with this process. Thank you, everyone.I do have but don't like the resulting sonic signature (via vinyl [mono & stereo carts] and SACD) of Tung Sol KT-120s as used in the HP amp. To me, over Spatial Audio Hologram M-3 Turbo S speakers, the KT-120s present a much flatter albeit brighter sound stage than do the stock PrimaLuna EL34s which to me provide what must be my "preference sound" i.e. a more-defined, lusher and layered 3D image.
On the preamp I changed out the stock rectifier PL tubes to a pair of Phillips 5R4GYS and also changed out the first two stock gain tubes to a pair of Cifte and Brimar.
All of these tube changes occurred within the past several days to past week and with limited research prior to purchasing. What prompted the initial post here was that I felt I jumped the gun and that I should have posted here first before diving in and buying all of these tubes. Reading only what UpscaleA posts on its website to describe characteristics of select tubes, I was about to pull the trigger on a set of Winged-C power tubes (with the expectation that this would deepen/further enhance my "preference sound") but I didn't want to go that route if a consensus was that I was going about this all wrong from inception. I will now be guided by everyone's comments and I very much appreciate your collaboration.
