Desktop DAC+amplifier to drive the DT 990 250 Ohm (maybe extended to speakers in future)

[twsecrest]

I do know how it works, but I had hopes that there would be cheap dedicated devices that take RCA input, generate matching reversed signal, and send across XLR to whatever other device needs balanced input; to be placed before long cable runs / directly behind amp. Thought now that I think deeper about how one could be made, I realized it would probably mean yet another amplifier, so that's pointless anyway...

I guess you could split the signal coming from an RCA jack, into two separate signals, so your sending two weak signals

Hence why I mentioned it would turn into yet another amplifier, to keep the same level of the signal. Just better to get the initial amplifier as balanced unit and be done with it...
