Hale Rev 3s

I've just gotten a pair of Hale Revelation 3s. I've just bought a Marsh A400s amp, and am planning on the Antique Sound Lab Hurricanes for tubes.
My question: do any Rev 3 owners find that tubes can't provide enough current to control this speaker?
I'll have them in a dedicated listening room: 9.5' (H), 13.6' (W)x 20'(L). The long ends of the room will be soundproofed with ASC soundproofing strips and the walls will have tube traps (I got a million of them back in '88). Hardwood floors (but with a carpet eventually), dedicated circuits, [FIMS outlets], Modulus 3A, Arcam FMJ 23 CD player, and perhaps Nordost Valhalla speaker cable (right now I have the Shunyata Aries interconnect and Phoenix speaker cables, Shunyata Power cords, PS Audio Power Plant and Ultimate Outlet [high current edition]. I put my Versa Dynamics 2.3 in storage years ago, but am buying a new turntable as soon as I determine the best one.
So, that's the setup. What about the Hales? Current hungry or ok with 200 watts of tube power?

jrd:
I'm interested in what wattage you think would be appropriate for the Hales. What factor would make the 200 watt amps unsuitable? I know the Hales drop to 4 ohm between 50-600 range. I've already spoken to Tash at Divertech and he seemed to be aware that the Hales dropped to 4 ohms, but was quite confident there'd be no problem driving them.
Just for background, in case anyone didn't read this, when reviewed in Stereophile by Robert Deutsch, the Hales were powered by the Sonic Frontiers Power 2 amp, which has a power rating of 110 watts. Deutsch found this quite sufficient for reviewing. Fred Kaplan, in TAS, advised a "minimum of 100 watts per side," so when you say that, I'm just wondering if they neglected to mention something you're aware of.
Thanks for the comments!

thanks, Ohala. I'm noticing that, with the Antique Sound Lab 1003 integrated, I'm not getting very good imaging. I'm wondering if that's a matter of using the amp on the 8 ohm taps, the low ceiling in the basement (less than 7' high and with joists hanging down, which might be causing weird reflections), or the lack of power.
My dealer called me today to say that the Hurricanes can be shipped on Friday, and the Marsh amp is scheduled to arrive tomorrow, so I'll know pretty soon!
By the way, do you run your speaker from the 4 ohm tap? Oh, that's right, the Classe is solid state. Sorry, I forgot. I'd seen it suggested that the speakers be run from the 4 ohm tap. I tried that, but it seemed that the sound got murkier. A small mystery to be solved.

into lower impedances, I imagine the KSA 50 would deliver something like 100 watts at 4 ohms. That certainly should b enough power in a room that's 13x15, unless you have a 30-foot ceiling!
I'm quite sure it would be acceptable, given that power would only be 3db louder if you were driving them with a 100 watt amp. The Krell, even an older model like the KSA 50 should do fine! If you WANT more power, fine, but I've run the Rev 3s with a 30-watt Sound Labs amp, and it sounded fine (although the basement is too large to be filled by such a small amp).

One more thing: I'm driving the Rev 3s - for the moment - with an Antique Sound Labs 30-watt Class A integrated. It sounds okay, but obviously, when it hits crescendos, is less articulate than it could be. I've replaced the driver tubes - that was a VERY good move: the old tubes had NO highs, which, having had the amp for a week, and setting it up in the basement temporarily (low ceiling, walls 10' away on one side, 30' on the other [I'm fully aware of symmetrical setups, by the way] doesn't provide the best in sonics. Still, I can hear substantial low-level detail even in this setup: the flutists' taking a breath between phrases; pages turning, things like that.
Just thought I'd put my original question into perspective here: the smaller amp works, but the eternal question looms: how much is enough.
