Sorry for the question if it's been asked before. I acquired 2 Pass ACA DIY Amps. Is it possible to use them as mono blocks to drive headphones using a balanced XLR cable?
Let me see if I can explain better what I'm asking. I have two Pass ACA amps, both v1.6. I'm asking if I can run two 3 pin XLRs cables out of my RME ADI 2 DAC...1 (right) to one amp, and 1 (left) to the other amp. Toggle the switch down on both to put them in bridged mono, and use a 4 pin XLRs cable from the headphones that terminate in 4 banana clamp ends (neg/pos & neg/pos). I would connect one set to neg/pos to one amp, and the other neg/pos to the other amp, to the Speaker red to output A black & Speaker black to output B black of each amp. Would this work for a pair of hard to drive headphones (Hifiman HE6)?
Yes.
If feeding from an XLR you don’t need to move the switch out of the middle position, as XLR is always bridged.
