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!

That’s exactly why I traded in my Reference 5’s.

My Ref 3’s: hyper-analytic, modern presentation.

 

@curiousjim Too much money… too much weight. System in upstairs bonus room,  

I can’t even imagine getting your Ref 5’s or G5’s up my stairs. Bribed 2 young neighbors with Macallan just to get the Ref 3’s up the stairs. 😏

Trying to avoid it. We shall see. 

My new Mullard M8136 arrived today. If they threw a blanket on my system, it is a magic blanket… warm & luscious, yet dynamic… my new favorites. I hope this feeling lasts! Thank you.
