I used to own the eD A7s-450 (the "loudest" performer in the GTG) and have since traded it for a HSU VTF-15h in rosewood. The HSU may not play as loud (by a few dB), but the low bass (read: below 30hz) creates a much more tactile sensation in my room. The HSU is also more musical to me.
For anybody who read the review, the Rhythmik was played in an "unprotected" mode to get those high output numbers. It was at HIGH RISK for bottoming to generate those numbers and required careful and close monitoring. The HSU never bottomed. Not once. The Rhythmik's spl performance was much less enthralling with the protection circuits engaged.
If I were going to get a Rhythmik, I would look hard at the FV-15HP. I've heard an FV-15 and an FV-15HP and the HP version is truly impressive...and almost 50% more expensive than the VTF-15h. I would personally rather have an FV-15HP than an SVS PB13 ultra, based on my listening experience.
However, back on topic. I've been very pleased with my HSU VTF-15h and I haven't noticed the reduced output capability from my A7s-450 at any frequency, since I wasn't running either of them on the ragged edge to begin with. I do find that frequencies below 30hz feel much more present in my space than with the eD (even using a lot of EQ). The HSU blends very well with my Arx A5 towers, which are a critically damped design.
