I heard the Art of Sound Tycus sub with a pair of Audio Physic Virgo IIIs speakers at a dealer in CT. I was really impressed with what I heard. While I did not do a direct comparison between the Art sub and the Rell Stadium III sub, from what I remember of the Rell, it now has some serious competition. I was told that both subs use the same amp. The Art sub seemed to have better pitch and integrated very well with the Virgos. It seemed to be faster than the Rell. And best of all, it looked better and was less expensive than the Rell.
