This morning the first thing I did was disconnect one speaker at a time, thinking if there was serious crosstalk I would still hear sound from the disconnected speaker. But not at all - dead silence when disconnected. Next I reversed 1 of the speaker leads and that didn't solve the problem. However, instead of the weird disembodied voice in the sky I usually get when some wires are crossed, I got a super wide soundstage but the vocals were not centered - they, too, were spread across the soundstage. But it was clear, not the distorted sound I usually get when doing this. And I have to say, now that I have put a pair of TJ meshplates in it, the sound quality is as good as I have ever heard in my system. Lush female vocals from Jane Monheit, and on another recording I could hear (slightly) the snare wires vibrating against the drum head. Truly lovely sound, so it will be worth it for me to get this fixed. I don't know if it is from a standard design or unique to the builder and I have yet to discuss this problem with him. I want to listen for a couple of days and then call him and discuss it in detail. My first desire is to send it back and let him work on the issue, but we shall see what transpires. And I am willing to take live voltage readings (yes, I have a death wish apparently), but not at this time. Maybe in a couple of days. I have built several Bottlehead kits and on the first couple I just plugged them in and hoped for the best and they always worked. But I finally built a stand to hold them upside down so I would not have a shakey playing field and that helped a lot. If it comes down to my doing voltage checks I will build a similar stand before getting into it. I live in Shreveport, Louisiana. One more odd occurrence. I hooked the amp directly to my DAC using a couple of EVS attenuators that Ric Schultz built 17 years ago - one of my prized and most useful possessions - I will own them 'til I die. When I played the track I use for left and right checks, the voice barely moved on the right side and the "I am now standing beyond the right speaker" track the voice was still inside the right speaker and to the rear. The left channel had the voice move a little to the left and the "standing beyond left speaker" voice was huge and way to left of speaker. So the 2 channels are acting differently. I am open to new comments, but I think any actions will have to be later in the week after I get a chance to talk to the builder. But man, it is playing now and the quality is to die for.
