If anybody is still listening, you might consider some new production tubes. Ray's Select 12au7 are nicely balanced tubes. I also tried new production Mullards. Currently I am using PSVane Horizons (GASP!) in my Backert Labs Rhythm. If you want a more controlled sound with lots of depth, give them a try. At 65$ pair from Amazon (Gasp again!!) not much to lose.
Additional Preamp Tubes
I am looking to purchase an additional matched pair of NOS tubes for my PS Audio BHK preamp. I currently own Brimar CV4003, Telefunken Medicals & Siemens Nickel Plate.
When I began building my system 3.5 years ago, I wanted revealing - accurate. Now I want a tube that is more musical / warm, similar to the Brimar’s with a touch more warmth.
My system: Aurender N150 > Briscati M3 > BHK > Moon 760A > KEF Reference 3’s. Rega P8 / Hana ML > Gold Note PH 10 on analog. Cables are Kimber Select from sources & Transparent Ultra’s pre > amp > speakers.
ChatGPT recommended Mullard CV4003. There is a pair on eBay from Valve Tubes. Please let me know your thoughts on this and other potential tubes, and if you have any experience with Valve tubes. Thanks!
