Liked the Nautilus 805 but found better?


I really, really like my 805s, but, alas, the bass. I'm looking for those that fell in love, and then found something better. Opinions on the 804's have been mixed. I cant see them being $1500 better than the 805. any and all suggestions appreciated.

A few things can help immensely: a) Vibration control devices betweenn speakers and stand. Walker Points I use are excellent. Marigo dots as explained above; b) increase current to your amp. The new copper FatBoys from Electraglide are bass "oriented" c) modify crossover; d) change speakers: e.g. Audio Vienna, "Mozart", Sonus Faber "Grand Piano" Impact new speakers (see their web site)
Gthirteen, what electronics are you using? This could be the source of your bass concerns. I have a pair of Nautilus 805s, and am using Bryston amp & preamp. I've been pretty happy with bass. The Bryston gear (particularly the power amps) are known for their bass authority. A change there could give you what you are looking for. Good luck.
Rega Planet CD, CJ PV11L preamp, McCormack DNA.5 amp, AQ Diamondx3, Lapisx3 ICs, and AQ SA-40/CV-4 Biwire (2 15 gauge cables, 1 silver 1 6 9s copper).
Ghirteen: You may be able to increase the bass by changing a few tubes in the preamp. I would discuss the possibility with Kevin at Upscale. And also Pods or whatever as mentioned before.
