Question on Luxman L-AX550ii balanced inputs

Hi all.

I've been googling like crazy all day, and I cannot seem to find an answer to this simple question.

What is the MAX input voltage that the balanced inputs on the L-550AXii can handle? (Ok, maybe not simple.)

I'm looking at a source that puts out 5.8 volts max, and I'm concerned that that might be bad for the amp.

I've written Luxman, but I don't know how soon they'll get back to me, and I'd really like an answer.

Thanks!

@nwres Good idea. I was thinking of Hudson Valley HiFi -- assuming they'll answer a support question from someone who is not a customer.

In any case -- I thought maybe I could just use the single-ended inputs, but as far as I can tell, their max input voltage is 2.5V, and the Spring 3 has a single ended output of 2.9V.

I may just go to plan B and check out the Schiit Yggdrasil.

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.
