Headphone amp - how to integrate into system?

    My M-DAC functioned fairly nicely as a headphone amp for my HD600s but as per my other thread it's shit its caps all over the place and until I can have it looked at it has been ousted in the meantime for a Topping D50. Neither this nor my amp have a headphone output - but could I run a headphone amp (such as a JDS Labs Atom) from the tape output as this would be a line output? I'd have to remember to mute the amp's output every time I used the headphones though.

    The JDS offers RCA out as well as in - presumably this means it could in theory also be sat as a pass-through between the D50 and the amp? Although saying that, ideally I wouldn't want to put another device permanently in the signal path unnecessarily. It would, however, mean no need to even turn the amp on for headphone listening...

    Yep, tape-out can be used as a line-in to a headphone amp.

    I’m glad this came up.
    I have no tape in/out on my preamp but it does have spare preamp outputs, is it possible to connect a headphone amplifier via the pre out? It’s a passive preamp if that matters.

    I don't see why not, just be aware as they are pre-outs, they are affected by the volume control on the preamp, unlike tape outs which are line level.

    Thanks for confirming it'll work chaps. I also like the switchbox idea Tim, £16 seems good value.

    I'm taking the M-DAC to mansr in a couple of weeks' time for him to recap it and once it's back I will make a decision as to whether to reinstate it or sell it and stick with the Topping D50 and a separate headphone amp.

    Hmm. Seems it might be a lucky dip in terms of quality... In which case I'd do just a well starting off with using the built-in pass-through of the headphone amp and seeing whether it has any detrimental effect on the sound (I suspect if it does, it'd be negligible).

    I've used the pass-through on a number of quality headphone amps (Musical Fidelity, Fostex, and more)

    Never noticed any real detrimental effect - can't see the JDS being any different (gets great reviews...)
