Best preamp output option for headphone amp hookup?


I have a Spectral DCM-10 I'd like to hookup a headphone amplifier to.  There's a tape out, which is an obvious choice, but is it the only choice?  There are also the two coupled outputs (AC & DC).  If those are usable headphone amp hookup options, is there an obvious 1-2-3 order in choosing between the three?

Thanks much!

Won't the Spectral drive headphones directly?

We make tube preamps and *they* can do that...
If you have not chosen a headphone amp you should check this out

Phenominal sound for the $$$ has three inputs, balanced, rca, and 1/8 mini on the rear panel.   Best $500 I have spent on audio in a long time.
The shortest path from the DCM-10 to your headphone amp is almost certainly through the tape output. That's how I connected my headphone amplifier.

Roger that. Thanks very much for the response!
