Quick feedback to my RCA Grey Glas 1941 vs Stock Psvane paired with WE300b.
Compared both rather excessivly past 2 weeks with different HPs.
For Susvara I definitly prefer stock Psavane tubes when paired with WE300b. Grey Glas add a bit of clarity, detail and attack, but ultimately take something away from the mids, the sound is much less thick and tubey with on Susvara with them, there is less body, which ultimately makes them a no go for me. I felt that the layering took a hit too with Grey RCA.
For Atrium and Verite Open they work very well, with stock Psvane the sounds is bit more muddy and thick which isnt really needed considering the ZMF tuning, Grey Glas RCA help to clean up the sound and do add bit more detail and punch.
Its all about synergy I guess. What me makes me wonder what would be the proper upgrade from Psvane for Susvara, so the thick full bodied sound could be maintained, adding better technicalities like resolution, and better layering.
Currently I have this Fivre 6SN7GT incoming, very curious how they perform and open to other suggestions.
