Best tube dac available?

I also have the Modwright Elyse DAC, find it to be a fine player. I still have the stock tubes installed. 

I owned a Lampi BIG 6 (did a LOT of tube rolling) and it was wonderful then heard a Bricasti M1 and it was head and shoulders above the tubed Lampi in my system. The M1 was more dimensional and the soundstage deeper and wider. Have not looked back!

Modwright Elyse - Tungsram 7DJ8 signal tubes, Philips 5R4GYS rectifier and HIFI Tuning Supreme Fuse.  Amazing details and dynamics with KWA150SE in bridged mode.  Best of both worlds!!!

Sorry Skos,
 but the B6 uses small signal tubes…not the same as the big bottle DHT tubes used in the Level 7. I used to have a L4 then moved to a Big7 and finally to a Golden Gate. Big step up everytime. In addition, I have the latest Ladder R2R PCM setup and DSD 256 capability.

The other thing is that I have become tube addicted, as I now roll rectifiers and output tubes with wild abandon to modify the music presentation. Tons of fun.

The Golden Gate is simply phenomenal.
