Aesthetix Romulus Signature Upgrade Worth the $3,000 ?

I have Mullard 10M 12AX7s and also 6JD8's--the 10M's are fantastic tubes but very pricey to get the real deal. 

I'm currently running Tesla (authentic old stock--beware there are many fakes) 803S's and the Mullard 10M 6JD8's. For my tastes, this is a great combo. 

At at some point I'll likely try some triple mica 5751's. 

The Motorola I am using is the RCA mfg. M # 7058
SIG also gets you DSD

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.

Standby mode shuts the tubes down completely. Anyone here know what standby keeps powered up other than the blue light on the front panel? Are you guys leaving your units on for best sound?

As I remember standby keeps the power supply on, but not the analog board with the tubes.
