Thinking about buying a different tube preamp...

I've been making many changes to my system lately and was thinking of changing out the Jolida Music Envoy for something better. Was hoping for some ideas here.
My system is as follows:
Classe CAM200 monoblocks
Linn LP12
Jolida JD100
Revel Ultima Studios
Velodyne FSR12 sub
Running Synergistic Research Tesla Precision interconnects from the preamp to a PVC, then Synergistic Research Tesla Accelerator interconnects from the PVC to the monoblocks. Have the sub hooked up to the second output of the preamp.
Was thinking of spending around $3500 on something used. Most everything I have is used and I've been very pleased so far.
Thanks in advance for your input.

I've been doing a bit of searching and have come up with the Northern Electric 6sn7's and the GE 6sn7GTB's for their claimed low noise and extended highs.
I tested my Sophia's on the ancient tester my brother gave me years ago and found one of them questionable.
I like detail and extended highs, with good bass as well. Read about the TJ Full Music 6sn7's that were described this way. So far I'm leaning towards the NE's and GE's.

You should get all of that noise out of your system. Noise modulates with the music and ruins it. Send it back to the manufacturer, but get it done. Too bad

QUIET!! Put in a pair of GE wide grey plate 6SN7GTB tubes and they are so quiet. I'm very pleased. Was actually thinking there may be a problem with the preamp since both sets the seller sent me with the preamp were noisy. Thought I'd have to send it in for a check-up, and was prepared to spend some serious cash on a solid state preamp. Was leaning towards a Pass Labs XP-20 and almost ought one the other day. Glad I waited to see how these GE's sounded. Will wait for these to break-in before I try more. :)

I've been looking for the Shuguang black treasure cv181s and find they are for the most part available only in the East. Can anybody point me to reputable seller?
