This is an interesting thread because although at the moment I do my listening via my headphones I do have a pair of old (20+ years) DCM Time Windows 1A and an Adcom GFA555 which are in storage but which I would like to use again some time soon.
So currently my Singlepower MPX3 has a pre- amp function built into it. I also own a Monarchy NM24 DAC which has a line stage which currently I use as a headphone amp using an rca to 1/4" jack built by S2 Audio. BTW, what is a line stage?

So I was wondering if you all think if either the MPX3 (w/ lots of mods) or the Monarchy Audio NM24 would be better options than my old (also 20+ years old) Adcom GFP500? I have been looking for a GFP750 by Adcom which many have recommended as a great pre-amp.
I am sure the answer will be to set them up and try all to see which I like best.
