How to connect two amps with one source?

I want to connect my modded Ack dac (with one set of RCA outputs) to my tubed headphone amp (Singlepower Supra) and power amp (AVA FetValve Ultra 550).

What is a way of doing this that will have the least effect on the sound? Do I need to use a line router or switch box, or will an inexpensive y-splitter work at the output of the RCA terminals?

i suggest a simple mod to the dac, which will create a second pair of analog out females.

i have often thought that digital designers furnish dacs and/or cd players with 2 sets of analog out connectors.

You mean an internal Y-connection. Why not?

Well, if the units are well-designed, a pair of Y-connectors will be fine. This means that the dac has a low output impedance and decent current output and that the two loads each have a relatively high, constant and similar input impedance. I do not know any those devices, so I cannot advise further.

A switch, of course, will do fine, too.

Just having multiple outputs does not mean that they are independently driven. If not, and this is more common than otherwise, those outputs are simply Y-ed together.
