Pq showed me about half a pallet of that valve Mark. He was saying how he liked them and showed me his stockpile. Audio note won't run out.

But as ever YMMV and all that :)
Odd how I completely forgot that discussion !
Was that in SE or PP circuit, Steve ?
It may be they do something nice at small-signal level but not at higher levels .

I think it was a push pull EL84 with phase splitting transformers.
Mind you, I knew far less about getting them right than I do now, so the lousy sound might very well have been down to
my inexperience.

I was wondering wat would be the best solution. Using a 6463 linestage for both DAC and Pre-amp or is it possible to combine a 6463 for DAC and 5687 for a preamp? Any sugestions ?

regards,
Marcella
