Tube for aesthetix pandora / romulus


Hello,

I own an aesthetix pandora dac and i am thinking of upgrading its tubes:
- 2 E83CCS or 12AX7
- 2 6922 (6DJ8)

I have been advised to get mullard, siemens or telefunken nos valves

I don't know anything about tubes...

Would you have recommendation? Advises? Tips? Good tubes sellers?

Thanks and regards

I have been a tube owner for years and years and have gone with tubes from the manufacturer every time. They match them and know what sounds best. Often they will have a signature line (Jim White knows what tubes he feels are best and puts them in his sig series). I've heard people put different tubes in my gear or other gear and it may change the sound a bit, but a few times I felt it hurt the sound. If you decide to tube roll, I wish you luck as it will cost you a lot and you may or may not even like what it does. JMHO and there will be at least ten others who will say I am wrong,

The best way to go about this is to call The Cable Company. Especially since you don't know a lot about tubes. They're extremely reputable and honest to deal with. Also, they ask every customer to give them some feedback all purchases. They'll tell you what tubes Aesthetix Pandora owners like best.

have happen when you change the tubes?
