Amplifier advice from Ohm Walsh 100 Mk. II owners


I am awaiting a pair of Ohm Walsh 100 Mk. II speakers. My current system uses a Rega Brio 3. (49 watts at into 8 ohms, 64 watts into 4 ohms) I suspect it may fall short with the Ohms.

The room is around 30x20, with a cathedral ceiling that extends up to 16 feet. The system is along the long wall, and most listening is done with 8-10 feet.

The amplifiers under consideration are:

Rogue Cronus Magnum (90 watts, Tube)
Wyred4Sound STI500 (250 watts into 8 ohms, 550 watts into 4 ohms, Class D)
Quad 99/909 (140 watts into 8 ohms, 250 watts into 4 ohms, Solid State)

Any input/guidance from other Ohm Walsh owners, specifically Ohm Walsh 100 Mk. II owners past and present, would be greatly appreciated.

UPDATE: I just wanted to let you guys know that the Doge 8 and Hibachi have both arrived. They sound fantastic with the Ohm amps and I feel pretty certain that they should keep my urge to upgrade those components at bay for the next couple of years. Thank you, both Marty and Foster, for the advice. I'm trying to get the components burned in, within my time constraints, but even now everything sounds fantastic, given the relatively modest outlay. I assume it'll only get better as time goes on. The Hibachi, at first, seemed less robust than the 200 watts implied, but after 2 days of playing, the initial question marks disappeared. As these are the first new amplification components I have ever bought, this is the first instance of burn in that I've had immediate experience of. I'm very happy with the Ohms. Despite having looked into them for the past few years, I hadn't imagined I would be buying a pair at this time, but the opportunity for a relatively close sale in a finish I like made it irresistible. I'm glad I took the plunge, despite this not fitting into the equipment map I'd had for myself. I think these Hibachis will be keepers and can do duty with a W4S DAC-2 as a preamp in a second system when the urge to try SET becomes too great and I'm forced to change things up. Thanks again, guys!
I picked up a second hand pair of tad hibachi 2 amps that should arrive week.

I'm trying them out as an upgrade in my second system driving a pair of Triangle Titus XS along with the sub. I'm expecting good things there.

Not planning to use them with any OHMs currently though except perhaps as a back-up if needed there. Would be interesting to try that combo though if I like what I hear with the Triangles.

I tried the Hibachis with the Vandersteen 1C speakers prior to selling them and they sounded great together. Given the similar sensitivity levels, I think you'll have an easy time getting a pleasing sound from the Triangles. Hearing the Vandersteens with my system after the Ohms made me appreciate the need for more watts with Ohm speakers, even the 100s.
I currently own a pair of Walsh Ohm 100 Mk IIs.

The Exposure 2010S2 is a first-rate match; this is with Naim CDX2 as source (Naim 5-pin-to-RCA interconnects), Nordost Flatlines as speaker cable.

The Exposure amp is quite transparent, and everything it retrieves - and I do mean everything - ends up being music; a great piece of gear, and a very high-quality match with the 100s indeed. Highest recommendation.

I never had much luck with the 100s in my 30x16 family room,
but they sound very good in a 17x13 bedroom. A very balanced, coherent sound, articulate without brightness, excellent bass - easily reaches into the 30s.
