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.
