Tube for aesthetix pandora / romulus

Jim at Aesthetix uses the best easily obtainable tubes and that is Russian. They however are not the best sounding. If you want a more natural sound you have to tube roll. In my system I like Mullard's and Amperex.

Aesthetix uses the same tubes whether its a standard, signature, or eclipse model. In my Pandora dac I love the Mullard 10M gold pin 12AX7 and 6922. The 10M are rated for 10.000 hours and are more open sounding than the standard Mullard UK tubes. You will pay a premium for these and they are very hard to find.

The engineer who says tube rolling is rubbish does not have the best ears. Don't feel bad lots of engineers that design don't always have the best ears. Tube rolling is fun and can easily be heard. Try it you will like it. Brent Jesse, Andy at Vintage tube are both good. Don't feel bad about trying ebay. You will save money over the other two people. Make sure they give you at least 7 days to return them if there is a problem. Brent gives you 30 days to try and you can return them for other tubes even if you don't like the sound. I thinks this is great.

I tried Amperex ECC83 Holland tubes from the 50's (Haarleen plant) and did not like them in the Aesthetix. I don't see how phillips would be better.
