Im my case, yes.
As is common with Odyssey amps, mine is custom made by Klaus. A moded Kismet. I dont know how much of an effect it has, but he asked me for multiple voltage readings from my house service so he could tweak the bias. It is cool how he will work directly with you for your set up. As is always mentioned, call him after 10pm cst. He's nocturnal.
This is definately a quality built amp. Makes the build of my other componets look cheap, but their not.
Sound wise, Im quite happy. No desire to upgrade although Id have Klaus convert it to a mono block and buy a 2nd if budget allowed. It drives my low efficient Magnepan 1.7i s fine.
If you go Odyssey and want to save a bit, look for a used one and send it in for an update. Shipping might bite you. I picked mine up directly from Klaus and got a very good deal.
