I own & I am extremely happy with my latest-version Headroom Max (with HD650s with a Zu Mobius cable); Headroom's new version has a new "reference module" that
is stunning, a significant improvement over the original Max. It is built as solid as a rock, generates no heat so you can leave it on all the time, and has a small footprint, & takes no care & feeding like tube amps. Even if you have a tube amp, I would have a Max as a backup. It's one of the great bargains in high-end. The midrange & vocals are smooth but not forward, bass is authoritative but not boomy, highs are sweet & not tizzy. Soundstaging is appropriately deep with minimal inside-the-head affect. It is very addictive. Wes Phillip's 1999 (I think) Stereophile rave-review of the original was very accurate.
By the way, the Senn 650s are way more natural & better in every respect than the old 600s. (My cdp is an Accuphase DP75V. ICs are Kubala-Sosna Emotions. Power cables are TG 688s. I also use a BPT BP Junior power conditioner on the CD player. A great little headphone system, I believe.)
