Direct in for Leben CS600 ?

whoops, wait a minute....you are talking about the input which bypasses everything else, right? sorry, yes, I use that for the cd and it does sound better. I thought you were talking about the bypass to kill the preamp so you could use another preamp. That I've obviously used as well. and also a great function.
Sorry...

Yes, it worked great. I used it with another preamp that had a built in phono stage so I could play vinyl while I was borrowing it. Great piece of gear.

Not yet. But I'd like to with a Shindo Monbrison jacked into it.
