Ok, auditioned this amp last night and the creator hasn't even named it yet. It's as powerful as an E12, and has a similar sound signature, but it's warmer and has a much better soundstage.
This came about after I lost my beloved E12 on a flight. I wound up buying a C5 and while it was a very nice amp, it had a bit less power than I would have liked. Anyway, I posted a pic of my new C5 with my name on it and one of my friends posted that he knew an amp that killed it for a 3rd of the price. He directed me to Andrew Pallison at JBSound in the UK. Andrew also builds Objective 2's, and I ordered one of those from him.
Andrew came over my house and delivered both amps personally. Of course I opened the Objective 2 first (who wouldn't??) and was extremely pleased. Wasn't too excited when he thrust his new creation in my face, but as a courtesy I opened it and listened to it because he was there.
It looked exactly like JDS Labs cMoy, but it sounded completely different. This was pure clean power man, and the soundstage was godly. Andrew says it has 75 hours battery life from two Duracells, but it's non rechargeable, so you have to replace the batteries yourself which is a downer. Andrew also says he uses the same capacitors as a famous high end 1980's tube amp.
He's charging £50 UK pounds for it right now. JBSound is basically a 2 man operation and can't really handle high volume, but Andrew says he thinks he can handle it if it happens.
Andrew doesn't even have a website yet, but he has an eBay account I can link to, he says he'll list the amp tomorrow when he thinks of a name for it:
