How to connect two amps with one source?

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.

A preamp with two sets of main outputs may or may not have independent buffer stages for them.

If it does not, then in effect it has an internal y-connection, that will perform no differently than an external y-connection, aside from possible cable effects which should be negligible because the y-adapter should be very short.

Creating a separately buffered second output of the dac would not be "a simple mod" for most users.

i do not mean an internal y connection.

consider a preamp with multiple inputs and outputs.

in the same way, consider a digital source with more than one output. you would have two sets of analog outs, the same way a preamp can have two sets of main outputs.

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?

tsuch an approach would solve your problem.

I would not use a cheap one. In the past when I was a dealer for them I had Audio Quest and XLO make up ones for me. You can try Signal Cable and Morrow and others to see if they would make them. The chain is no better than it's worst cable so if I had good ones elsewhere I wouldn't use a cheap on at the beginning of the chain.

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.
