I would like help/suggestions regarding the best way to split the signal from my Bifrost DAC, so as to allow it to feed both my currently owned Lyr, as well as my anticipated Asgard 2, whenever it finally ships/arrives. I would rather not have to disconnect/re-connect my rca cables from one amp to the other everytime I wish to change amps.
Oh, and no, I do NOT necessarily need/want to run both headphone amps simultaneously, (however, that possibly would be a nice benefit at times). Rather, I would like the option of leaving my Asgard 2 running over extended periods of time so that I might spontaneously/"casually" listen whenever the mood strikes me, (over nights etc.), and saving my Lyr tube life for when I plan on more "serious" listening sessions, thus enjoying that which the Lyr has to offer, without wasting tube life while I am away from my system, or falling asleep...besides, as nice as the circuit topology might be, that toggle switch on the rear panel is a bit of a challenge when I am not right next to my system amp..
So, what suggestions do you have regarding an analog signal switching device, that will minimally/inaudibly(?) degrade the signal? If I DID wish to listen to both amps simultaneously, would that change the answer?
Current signal chain: Digital signal source (Older model OPPO multi-disc player) >>> Bifrost DAC >>> Lyr Amp >>> Sennheiser 650's... and would ultimately desire that Asgard 2 amp next to the Lyr...
I look forward to your input/responses, and thank you in advance.
P.S. Despite reading several threads, I am still unclear as to the better/"best" choices for a headphone extension cable, as I must often sit/work at a distance from my amp that is greater than the length of my 650 cable allows...might like another 10, or possibly 15 feet at the very most... extension cable suggestions...?...brands, makers, sources...?...
