What made you prefer the 140? I had an AD140TC (a different amp, I know) and kept always going back to the AD200B, so I sold it to a friend. I might still profile the TC though.
I have the "other" OBC210 (the one that looks like the OBC115) and find it very similar to the 410 sound wise, just less loud.
You have the OBC210, do you also have the OBC115?
I think I scored a good deal on a new old stock OBC210, at $650 (the tax and shipping makes it less than a stellar deal, but I imagine these are not easy to come by). I also have a OBC115. I'm curious, if you have both, how you feel about one vs the other.
