For my first DIY build I made a standard BOM CK²III - it worked perfectly first time. Since getting a pair of AH-D5000's it has once again become my main amp so I'd like to tweak it as I made two newbie mistakes and no doubt it can be made better with better parts. My searches could find no mention of these changes, probably due to the multiple spellings of the name. Not that I have any idea what site I was reading - it was nearly two years ago!
1 - I built it with a gain of 4.1 and an expensive 10K stepped attenuator. I listen at step 3 or 4 and while this isn't a problem with volume it is generally agreed that amps perform better when not near their quietest, so it could sound better. Should I reduce the gain, buy a 50K pot/attenuator or both?
2 - I remember reading at the time upgrading one part (in the power supply?) made a big improvement - would anyone happen to know this magical part?
I also intend to install the ground loop breaker as it was omitted for testing and I never got round to adding it
A link to any thread discussing mods would be great, if you have one in your bookmarks/favourites
