Dynaudio C2 II Signature VS. Revel Ultima Studio 2

As a previous owner of both C2's and C4's, I think you'd need a lot of room treatments to make the C4's work in that size room. The C4's are superior IME to the C2's, but neither did well at low to moderate volume levels, which is why I eventually moved on.

I know I'll get torched for this... but I'd go with Harbeth M-40.1's... very ordinary looking speakers, but very musical, not picky with amplification, great with jazz & vocals and you don't have to turn them up to ear splitting levels to have fun with them. Also recommend you ditch the solid state amps in favor of a decent tube amp.

Pdreher - No torching but the MKII/Signatures do much better at low to moderate listening levels compared to the originals.

My C4 signature II models do fine at low volumes. The older C4's are reported to be harder to make come alive. But, I can only report on my series II models. I listen at 80-83 dB average, and things are just fine.

Bass is tight and actually could be MORE pronounced in my book. I added stereo DD10+ subs to get the very bottom firmer and effortless sounding. It worked out real well. But to say they are boomy? I haven't heard that at all. The Dyn Audio sound is much more neutral than most speakers. Some don't like that. I like it...fast, open and dynamic. Midrange is especially intoxicatingly good on C4 series II's.

The C4's will really be hard on your electronics and source material, though. You will hear differences in electronics like never before. Source recordings are ALL different sounding, too. Resolution is WAY better than any speaker I've used in the past. Some will say this is a bad speaker since it says things are poor when they are. Many don't want to "hear" that. I don't, but I can't blame the speaker.

I took actual room EQ dB values and they are commendably flat. Remember, bass can be tricky to measure because of room nodes. Stand in the right place and it's flatter, or not. But the overall tone is NOT tubby.

As a audiophile and business owner I Have owned & sell both brands/models
I give a slight edge to the Dyna's because you specifically said Sound stage & the sound stage is generally bigger and more accurate w/Dynaudio. Both are excellent would any among us not to be thrilled to own either?
