Building the Audio Note Kit 1 SET amp...

While I think the Tekton stuff should certainly be on your list, just be aware that their efficiency ratings are (like the DeCapos) probably a little optimistic. I've noticed that their ratings match the ratings of what the manufacturers of the pro drivers they use state which is fine, but Tekton is running their pro drivers behind a crossover and a tweeter that isn't as efficient as the main driver which in turn might be padded down a little. If someone formally tested the Tektons, I'd bet they'd be plenty efficient, but not as high as they are advertised.

This is probably why Tekton tends to like to recommend higher powered amps....or perhaps, he just likes to listen really loud! :-) Regardless, they certainly have to be more efficient than those DeCapos.

I'm hoping you pick some up, I'd be interested in hearing how they match up to the amps.

I wonder if Brian at A-Note could send you an amp that he knows is working properly to see if it does work with the Decapos. If it does work, then you know you'll still need to troubleshoot, if it doesn't, then you could save everyone a lot of time and trouble trying to diagnose a problem that may not exist.

Like most of us here, I'm pulling for you to get this sorted out to the point where when it's all over, you are absolutely thrilled with the outcome.

Best of luck and thanks for keeping us all in the loop.

Great news that they've finally gotten to the bottom of this. I hope your listening trouble free very soon! Thanks for the update.
