Revel GEM or Wilson Cub 2 ?

You may also want to consider the Krell LAT2 Speakers (avail. In Black or Silver). These, the GEMS and CUB2 are arguably the best stand-mounts in the world, and will handily out perform most modest-sized floorstanders. From my experience, the CUB2 is the front-runner here. The CUB2 (with port(s) contribution) will go down to around 40Hz, plus has an excellent top-end and incredible imaging. Also, the Wilson Stands are painted to match the CUB2, and are beautiful and available in many colors. All (3) retailed for $10K and can be had used for around half that amount. The Revel & Krell are excellent, no doubt, but the Wilson is unique in its performance, even better than the (lifestyle-designed) Duette that somewhat replaced it. Regarding the Revel Performa Speakers, these are entry-level hi-fi and I don’t feel compare to a state-of-art mini-monitor (stand-mount). You will get a bigger sound (bass and loudness), but not a better sound in my opinion, plus these stand-mounts are highly efficient and will require much less power to run and therefore be far more tolerant of different Amplifiers (Tubes, Hybrids, SET, etc.). Plus, can be backed-up close to a wall with out smearing the bottom end as large floorstanders do.

sounds like change for the sake of change. revel and wilson are awfully similar.

You would very likely enjoy the Wilson Duette very much. It is significantly more dynamically nimble, articulate through the midrange, and tonally convincing at the frequency extremes than the Cubs. Expensive? Yup, but very, very tasty.

Heard the Duette this weekend and was very impressed. All round great sounding speaker BUT the Sophia is just that much better.
The Duette is a little more room friendly though especially if you don't have a dedicated listening spot.

Personally, I feel that the CUB2 is sonically somewhere between the Duette and the Sophia. The Krell LAT-2 also dips down in the low 40s-Hz, with a nominal impedance of 6-ohms and weighs in at the same (heavy) 75lbs. It would be an interesting A/B/C comparison between the Duette/CUB2/LAT-2. You would need to find a Krell / Wilson Dealer to be sure. Easy for the CUB2 to be overlooked when you’ve got the Sophia and Watt/Puppy, that will fit in the same space.
