Making progress. The left speaker is done and has been playing for a couple of days.
I made the mistake of cutting and bending the wires the connect the NEO3s without realizing that the right channel wiring will be reversed. I don't want to unbend the wires and rebend them in the new position, since I paid for "continuous crystal" copper wire and bending the wire once is bad enough. So I am about 3ft short on the 18ga wire for the NEO3s for the second speaker. I've got more wire on order from SonicCraft which should arrive on Tuesday. Everything else is done and ready to go on the right channel speaker.
I haven't made any attempt to set up the speakers and subs, and, of course, they have hardly any break-in, but the sound from the first speaker is VERY promising. Incredibly clear with nice tonal balance. I'm looking forward to hearing what the stereo pain will do.
These big caps are going to take a few hundred hours to fully break in, but I'm amazed how good they sound fresh. I have heard that the sound gets worse before it gets better though - we shall see.
