The LD range of amps are great with the HD600s. So too are the DARKVOICE amps. I'm one of the few who own a FIGARO and it's a great little amp, and carries on the DV reputation of sounding excellent with SENNHEISER headphones. It grabs them by the scruff of the neck and gives them a good thrashing. One problem: the 110v versions have been delayed for a long time now, due to technical reasons.
Have you considered the Gilmore Lite? If you're looking for treble extension and tight bass, that's the best I've listened to short of the Zana. The M^3 and CK2III are pretty good, too, but the GLite has nice synergy with Senns. It may not have glowing tubes, but the sound makes up for it.

Considering everything you have said here, I would still recommend the Little-Dot MKIII. The folks over in the MKIII tube rolling thread have said some amazing things about it's abilities and strengths. What you may not know is that Little-Dot has just completed the new MK series lineup and all their amps are newly designed. Tube rolling options have been expanded greatly so you can tailor the sound to your liking. The design and build quality are exceptional and their customer service is one of the best out there. A MKIII would save you a substantial amount of cash, and that is always good!

Yes, you are correct. I guess I didn't realize that you wouldn't mind spending the extra. The MKIV and MKIVse are really great amps! Think bigger, better components, better amp design (OTL), GOLD bling rings, and tons of power.
While the MKIV standard has more tube rolling options, like the MKIII does, the MKIVse has additional upgraded components for that last little bit of improvement. You could NOT go wrong with either one, and if you have the extra cash to spend, the MKIVse IS the amp to get.
Of all my amps, my MKIVse is the only top of the line single ended tube amp I will ever need. I'm not even sure I want to go "balanced", as I am way more than satisfied with the MKIVse. Those might be famous last words, but the MKIVse impacts a person at such a high level, you may not want to have anything else.
