Is it possible to connect two amps to the same DAC using a Y-splitter, only switching on the one currently in use? Will the presence of a second, powered-down amp on the DAC output degrade the sound?

yes ... no degradation as far as i can tell ...

Should be no problem - I run two amplifiers in parallel in a similar manner (one has a loop return). Can even have them on at the same time - not that I can listen to two pairs of headphones at once.

Just make sure the splitter isn't crap (I'm not saying buy boutique cables, but there's some really bad stuff out there in the world of "hook-up accessories" that you can find in department stores, like hair thin conductors and fall-apart build quality).

While normally there would be little change of tone of multiple inputs from a DACX

You have to remember the reduction in input impedance .Too many and "highs" will be reduced also that the output from the DAC is "current limited" by a small value series resistance in front of the output audio chip/wont matter so much if output is discrete construction.

It's a TeraDak V3.1D NOS DAC. It has 8 DAC ICs in parallel, connected to the output sockets via a capacitor. Does that mean that connecting two amps in parallel (even if only one of the two will be switched on at any time) would not be a good idea?

 

[geetarman49]

there's nothing wrong with this approach (only 1 amp powered at any single time) ... many of us have done the exact same thing w/o issue.

Yeah it'll be fine.
