Salas hotrodded blue DCB1 build

Try polystyrene caps (Styroflex in Europe) - to my ears the offer the right combination of clarity and warmth.

Today a friend and I managed to use an old heatsink I for to finish hotrodding. Moved down from 3.9R via 1.95R to final 1.3R (= a litte more than 1A). The sound changed is pretty breathtaking. The presentation gets more solid, you get a lot more natural timbres (colours) and any hint towards harshness disappears. This preamp is absolutely unbelievable.....IMHO.

Cheers,

Here is my homely DCB1 facing sideways running 2R current, driving big_A speakers with F6 at a fellow member and neighbors house.
Good times.

Pinnocchio - Thanks for the leads. All look solid. I did some e-pay search work and lots of decent opitions. Thanks again

"I try to be cheap and unattractive as possible" - I love it! I should put that on my autosignature at work!

No problem. I personnally always buy the Modushop chassis but my friend buys the ones on ePay (the link I gave you) and it is really nice!

Ciao!

Salas, I was curious and deciding which value for the potentiometer in front of the DCB1 to choose, either 10K or 25K? I thought that 10K is too low for loading my DAC and phone preamp, on the other hand 25K, as you have mentioned may be a bit too high for proper DCB1 operation, even thought it would benefit by less loading the source equipment. The lowest possible distortion level is the goal.
I would appreciate for your advice.
 
I have just received the 0,47uF FT3 caps... Damn those are HUGE!! They even came in a wooden box...

But I have just tried some new interconnect cabling and to be honest I do not feel like changing anything for now... Sweet sweet sweet music :D

For reference, here is a photo showing the relative sizes of the caps.
