Sophia EL34-ST Tubes

I've had Sophia mesh plate 300B's and they were fantastic. 
No experience with the EL-34's though.

I would like to know how it compares to the KT-150 on a Primaluna too:)

KT 150 Primaluna valves for sale. As new. 

While the Sophia EL-34's were a huge improvement over the Tung Sol EL-34B's in my Unison S6, long term listening has revealed them to be too bright on some recordings.  I also tried the Gold Lion KT-77's and found them to be similarly bright while otherwise less impressive than the Sophia's.  Since the amp was voiced for EL-34's I have ordered the Psvane EL-34PH tubes (replica of the legendary metal base Phillips EL-34's) to try.

I will report what my listening experience is once they are broken in and I've had several months of listening to them. 

cellcbern44 , I would appreciate a report on the Psvane EL-34PH and how they compare to the Sophia EL34's. Thanks.
