Just realized I’m the one who started this thread..
I guess I should post my current setup, it’s been about 18 months since I’ve posted here..
Quick answer, I’m running (E.M.L. 300B xls) output tubes in my
Aric Audio Super 300B SET amp..
But I suppose the output tubes only tell part of the story, considering my amp has 10 tubes in total..
On the power supply unit I have a pair of (Sylvania OA3) and a pair of (Sophia Electric 274B) ..

On the amp unit input tubes are (Sophia Electric 6SN7), driver tubes are (Sylvania - Bogen 6v6gt), and the output tubes are (Emission Labs 300B xls)..

I use a Decware (Zrock2 ) to enhance the bass , the tube in the Zrock is a medical grade Mullard 12AU7

The DAC in use is the OPPO 205 modified by Modwright, tubes in the DAC are NOS Mullard E188CC, and a RCA 5R4GY in the Modwright power supply..


So far the EML 300Bs are the only ones I’ve ever tried..
Looking at the WE 300Bs , or possibly a set of Psvang, or Sophia Electric..
But for the price of the WEs I could have a Decware “Rachael” on order..
These 300Bs are so expensive it’s discouraging to buy more than one set of tubes..
Pretty happy with my current setup..
Streamer/Server- InnuOS- ZEN mk3
Cables( Hapa -USB and RCA) (T.W.L - power) (Zenwave-speaker)
Speakers- Tekton DIse / pair of Enzo subs..
Would like to upgrade the DAC to something else down the road..
(Holo , Aqua, SP1X, Audio Note) $3,000-$5,000..
The only other upgrade I would be interested in would be a set of VOLTI “Rival” Speakers, but at $10,000 to $15,000 it’s not an easy move..
But the Klipsch (Cornwall 4s) are looking interesting at $6,000..?!!
Happy listening to all ,
