Question on Luxman L-AX550ii balanced inputs

I managed to check with a Luxman dealer, and their view was that the output on balanced outs should be 4V at most.

So...I think I'm going to continue to try to get info from Luxman (though it hasn't been all _that_ long since I asked) and go for something with a more reasonable output.

I had the same question with a 595SE integrated and I was able to talk to Luxman US and they said 4V. Hope this helps. 

I was in a similar situation when I got my Luxman cl-38uc preamp. My CDPs balanced output level is 3.2V, and Luxman’s input is 2.5V. I contacted both Luxman’s and CDPs representatives about the issue, they both told me it’s a bad idea. Then I called my Lux dealer, and, after consulting with his tech, he told me there is nothing to worry about, since Luxman can take up to 7V or 9V (don’t remember now). Probably they had tech papers for the insiders.

Thanks @hasmarto.
