setup is netbook/foobar/m2tech/buffaloII/6v6 ....
with my 2.5 way 92db speakers (horns moved to another room for the holidays) ...

I listened it with zenV4 and f5, with both it sounded excellent, esp with zen cause zen needs the extra dbs (I was listening to it with dcb1) ...

Nick ... thank you for your design and for the unique power supply and all the members who contributed to it ....

now its time to play with some rectifier tubes and output caps ...

Is it easy to push the column speaker for slam with a Zen or an F5? I guess that the line gain came up handy.

yeap !
they are 91-92db, so the gain was much appreciated ..

the horns are 95-96db ... still some extra gain will be nice to have there too ....

With such low gain main amps yes, gain aids their dynamics even on sensitive speakers. There was a very easy to understand article by member Pano about gain distribution in the whole chain. A rather underestimated thing in home audio but every one involved in live and recording systems knows its of cornerstone importance.

yes, I have read that article, not long ago ...

btw pot is a cheap one, have tried it in dcb1 and it was fine for the job to start wth, later I replaced it with a khozmo one which was much much better of course ...
I probably put a khozmo in this line stage too - with z-foils this time ....

Khozmo has 25K too, hmm, could you try with 20-25K too to know what value you like best in your system and sources so to buy optimally when you will splash out for a posh pot?
