Got around last night to fitting 0.1uF bypass caps onto the yellow ebay film cap?
Stan B had mentioned it as a good thing to do...in his usual understated way of course...
flippin 'eck!
I noticed a difference right away, the mid and treble had "changed" somehow...it was a different kind of presentation?
More "texture" is how I would try to describe it?
Theres detail coming through I hadn't heard..really subtle stuff, for instance the WAY a guitar note is being strummed...sustain, harmonics, amplifier noise, all of that.
At first I thought I had lost a bit of bass depth - and I had - and there was less "impact", particulalrly with the big classical stuff.
But the detail was all there, much more so than before. Room ambience, mike noises...very distracting.
I left the Dac playing the telly overnight, I had noticed cap burn in before and whilst I hadnt expected anything (dont know why) with the wee 0.1uF caps I thought I'd give it a go anyway.
This morning the bass was back, big time.
A lot tighter and with more depth..the kind of bass you feel in your trouserlegs!
If you have done the passive mod..get some film caps.
If you have film caps...fit a bypass cap.
..dont ask why, just do it
