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.

Thanks @nwres.  The source does not have a variable output unfortunately.

I don't understand the math behind figuring the input voltage -- I have heard (but only on the internet) that a balanced input can generally take up to 10 volts input, but I'm not sure how much to trust that figure.

@nwres the source component (that I'm only considering at this point) is a Holo Audio Spring 3.

@jperry 2.5V max? I was under the impression that the output on most modern balanced outputs was 4.0V. Is it a different case for tube amps than it is for solid state amps?

Hey @jperry -- I did already see that, and I read the footnote. I wasn't saying I didn't believe you. I was trying to say that it seems that having such a low max voltage on the balanced input seems (to me) as if it's making the amp operate under a handicap.

I'm really new to the whole balanced input/output thing and there seems to be more to it than "hey, just plug it in."

@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.

@agbrace that absolutely helps! Thanks very much!

Thanks @hasmarto.
