Got the XPA-1's back and that's exactly what I got. On the plus side, I really do love the sound of these puppies. Reference volume sounds so effortless, and they do have quite a low noise floor. Is the noise floor lower than the bridged 5008? I'm not sure. They're both very good in that respect, and undoubtedly better than the P5000S. And the XPA-1's are musical.
I don't know exactly what it is about them but I would have thought that the noise floor aside, they would sound fairly similar to the P5000S which also put out 500wpc @ 8ohms, but while I was listening to music with the P5000S the pas week while the XPA-1's were away, I felt as if there was something a little off. Something that was not quite there. I thought that perhaps it was just the oddities of audio memory, and perhaps mood. But while waiting for the amps to arrive today, I was listening to more music with the P5000S driving the E100's and it still lacked that involvement for me.
The amps finally arrived and I hooked them up and there was aggravation. As I opened the boxes, one of the amps had a note that stated, "Main board faulty. Replaced Main board. Tested and working properly". The other amp had a note that seemed to indicate that they had done nothing to it.
I let the amps sit in the room for a few hours to allow any potential temperature differentials to even out, then carefully plugged everything in as before, and turned them on. Only took 10 seconds for the Right amp to start clicking madly (which is exactly what it did when the Left amp began smoking, which I assume was when the Left amp's trigger output fried).
I immediately shut the amps off and disconnected the Right amp's trigger input (which is daisy chained to the Left amp's trigger output). I tentatively turned the amps on again, and voila. This time, they both stayed on with no problems. After playing some music on the system for a bit, I decided to try reversing the daisy chain to see, if as had been surmised by myself (and the original tech I spoke to on the phone), the Left amp's trigger output was the culprit. So I pulled the mono trigger cable from the Left amp's input and stuck it in the Right amp's input, then daisy chained the Right amp's trigger output to the Left amp's input. Voila, it works just fine in this configuration.
So now I'm pissed. I specifically told the tech what the issue had been and wrote a separate note of each amp's (suspected) problems and included the individual specific notes in each box. After hefting these hernia inducing behemoths to the UPS store and paying $150 to ship both these amps back to Emo, they fixed one amp and didn't fix the other. Brilliant.
And despite being annoyed at the sheer stupidity of this situation, while I was listening to more music while checking to make sure that neither of the amps demonstrated any further problems, I realized that what I had felt was missing while listening to them powered by the P5000S was back. I don't know how to describe it other than simple sheer musicality. Weird. But now I have to ship the Left amp back to Emo AGAIN for the same stupid problem that they didn't fix.
