Sadly, I didn't get a chance to listen to it, but folks seemed to be pleased with the build process and learning at the workshop.
I hope to listen to it someday. If there was anybody else who was at BAF who listened to the ACP+ extensively please let us know what you thought.
I did pick up a chassis for Tom Christiansen's/Neurochrome HP-2 headamp and have the PCB on order. I did listen to it for quite a while, and found it right up my alley, very transparent, detailed, with a tremendous soundstage on Sennheiser HD650's. The prototype that Tom had there sold within the first hour of BAF.
After I build it, I will be happy to forward it to you for a listen should you wish, since we both live in the same state. I hope to be able to compare it to the famed discontinued HP-1 which my colleague has in the RTP area. I have a feeling one can get 90% of the performance for less than 50% of the original price of the HP-1.
