I don't know about the split thing? I heard the amps back-to-back at a dealer's that sells both. Speakers were various model Silverlines, and Reference 3A models. The Jota is good like I said, but I thought the KR amps were just "better", you know? I definitely was NOT impressed by the new lower priced Art Audio amps though. The dealer is a good guy, but he's a small "living room" dealer, I don't even think he's on the internet. I have his phone if you'd like it, don't want to post that publicly. I know he has the Atma-Sphere amps too, those I really like, but they are very speaker-dependent...
