NOS tubes for Aesthetix Calypso

I recently purchased an Aesthetix Calypso. I really like the preamp, however I would like to purchase some NOS tubes for the unit. First priority would be a liquid smooth midrange, second would be soundstaging, third would be frequency extension. I would really appreciate some Calypso owners offering up some experience and suggestions with the NOS tubes. I would also like advice on where to purchase NOS tubes. My system consists of Maggie 3.6r's, 2 Vandersteen 2WQ subs, A SMC modded McCormack DNA-2, Resolution Audio Opus21 cdp, and all Purist Audio cabling. Thank you in advance for all your help.

I have the same preamp. I’m very pleased with it. I’m also looking for tube replacements for both the 6922 and the 12ax7. I heard that Mullard 10M and Telefunken are fantastic tubes. I wonder where to buy these tubes.

I have replaced the standard 6922 Reflector tubes with a Russian Reflector 6H23P-EB, witch results in greater dynamics and “swing”, But a bit more edgy style… USD 22.5 at Parts connexion.

I have also replaced the standard 12ax7 with a new production of Tungsol ECC803S Gold Pin, witch results in deeper soundstage. USD 29.95 at Parts connexion.

I am still seeking for a more lucid and full born sound.
