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.

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.
I must be screwed. Kevin suggested that the PV-11 is one of the most "ornery" preamps re: "tube finnickyness". I'm using rubber pads with foam rubber pads on top of them (about .5 inches in diameter) to couple speakers to the stands. The Rega sits on a granite slab/innertube/granite slab/tiptoes/concrete slab floor(carpeted, of course) setup. The preamp has tiptoes pointing down into foam ruber pads/granite/tiptoes/floor, and the amp makes use of it's soft-shoe/coupling spike combo that is stock to the McCormack, sitting on granite slab and you guessed it, tiptoes. McCormack has Synergystic Research Masta Coupla, and the other PC are captive, stock. All cables are elevated from the floor.
Gthirteen: I think you know deep down that there is no moniter in the world that's going to give you the deep bass your looking for. Let's face it, physics don't allow. I own a pair of Sonus Faber Electa Amatours. Although they go as low as just about any moniter can, it still not enough. I wound up getting a REL Stadium II which integrates perfectly & allows my system to produce a full range sound. They can be had used for around $1700, but are hard to find. If that's too much you may want try the model below.
But the EAs go lower than 40 hz, right?? I don't need the lowest octave at all. If I could get flat at 40, (like the SF Grand Pianos) I would be happy. I know Paolo_Italy can supply the old GPs at around the $ that I could get for my N805's, and I might float them so that I could try them, as there's no SF dealer anywhere around. BUT I wish I knew more about them. I really, really think that what the 805 plays can't be beat for twice the price. Ho Hum..... Maybe I need some monster cables.lol
