THis was a cabling issue that is outlined by me in the second post on page two.
Tonight I crossed the finish line on my 2nd of 2 dripelectronics v2 LA2A's. I finished the first one over the weekend. It seems like there is some kind of roll off on the low end. It's kind of like an impedance mismatch or something.
Both units exhibit the same behavior. I ran some prerecorded material through one of the units and it seemed to reduced the bass greatly. While the prerecorded material was playing though one of the units I adjusted the limiter response and stereo adjust controls and the change in sound did not effect the bass response in a meaningful way.
I have the pcb mount sowters and I'm sure that the units have the input transformer installed with the index marker aligned with the mark on the pcb. I'm wondering if it's possible that both transformers could be mismarked.
Other than the bass issue the units seem to operate correctly (and in some ways they sound very good). Maybe a lack of bass is a part of the LA2A sound that I've never noticed. The record I'm working on has scratch vocals recorded though a reissue model and it sounds like it has an even response.
Maybe someone who has some experience with this circuit could offer some insight.
Thanks, William
