• The 6N23P (with/without EV suffix) and 6922 have gain factors between 32x and 33x.Thanks for the reply. I went deep diving on all the tube sites and 6N23P-EV is harder to find. But there are many equivalents. The only differences I could find is that the 6N23P's have lower gain ratings. So maybe he recommends that change for my efficient headphones?
Not sure about the swap from 6N6P to 6H30Pi? Maybe he is just trying to get rid of some tubes he has laying around? He says the "upgraded" combo sounds wonderful and will sound best with my collection.
The tube thing is always a crap shoot and very subjective. Sigh...
• Here is another thought (it works): Xduoo TA-20. $399, is a hybrid tube/SS, takes two 12AU7 tubes (great rolling territory), is balanced from input to output, compact size…
