Aesthetix Romulus Signature Upgrade Worth the $3,000 ?

I bought the Romulus Eclipse with volume control. As far as I know it does not have DSD.
For the 12Ax7 tubes try the Mullard square getter or goalpost halo getter or Amperex D-foil getter.
I believe these are from the late 1950s.

Audiolabyrinth,
Yes I’m using the CDP directly into the amp as I have with a long succession of CDPs and DACs. I gave up pre-amps many years ago. I’m currently using a McCormack DNA225 with Steve McCormack Platinum mods + ARC, advanced rectifier curcuit. These mods cost more than the amp but I’ve been very happy with the results. I’m considering a new tube amp in 2016 for winter duty.

As far as I know, the Eclipse and Signature are similar but Eclipse does not have DSD.

The Mullard 10M tubes suggested by rrsclyde are great if you can find them and want to pay the usual steep price required. If I win the lottery I’ll stock up on them. ;^) I may try something different instead of the Telefunken E88CC which might have a bit of hardness on top. I’ve already tried Amperex USA 6922 & 7308 so suggestions would be appreciated.

Lula,
I run a CEC transport into my Romulus as I think it's a bit smoother than the Romulus transport. I'm red book also.

Sorry audiolabyrinth I don't know what the difference is in construction or sound. That information might have to come from a dealer or Aesthetix.

I got the Eclipse because I don't plan on getting into DSD although I was assured that it could be added later.

I wouldn't say the transport in the Romulus is "lousy" just that you might find one that sounds slightly better.
