Why lots of B&W Nautilus for sale used?


I see a lot of B&W Nautilus speakers for sale, mostly 804s and 805s and some 803s. Considering the Matrix was around for 10 years, you would think there would be lots of them for sale from upgrading, but no. So is the Nautilus really better than the older Matrix overall despite what we hear??

Thirdly, is the Nautilus 803, 804, 805 worth the 60% increase in price in your opinion? Or triple what a mint used pair of Matrix go for??
I have a pair of N805s and it would be very difficult to convince me to sell them. I carefully considered many higher priced speakers but the B&Ws remained my favorites. The build quality seems exceptional.
Sugarbrie, . It does't get built much better than my Nautilus 805's. It stands to reason that a speaker with rave reviews like the 805's and 803's are bound to get a lot more buyers, and therefore a few more sellers. My friend has the big Silver Signature series B&W's, and even they are not significantly superior to the 805's ( a little more bass). The Matrix series is not a contender in any way IMO. Also, I think many of the B&W 's for sale are by people upgrading to another B&W. I use a REL Strata III sub with mine, and I suspect some of the sellers may not be using a sub, or perhaps have equipment that is not up up to the level of the 805's. If you are thinking of getting a pair of 804's or 805's don't think twice, they're alright!
Hmmm...I carefully auditioned 803N and 804N at home, and purchased neither. I had waited for B&W to ramp up production of the 804, as its size was ideal for my needs. Dealers explained that the 803N was a much better speaker, and that the 804N was developed following requests by the North American dealer network, to meet a $3500 price point. It was soon clear to me that it's sound was way too lightweight, and thus barely an improvement over the 805N. I soon found my reactions to the 803N to agree with those of a British reviewer I read last spring: the Nautilus floorstanders don't cohere in the nearfield, and require a good 12-15 feet before starting to sound integrated. As I sit in a 7.5' triangle it was obvious that I was hearing 3 different sets of drivers (the 400Hz lower crossover, as well the "hot" tweeter seem the culprits). Additionally I could not accept the extreme upper crossover/radiation pattern tonal shift accompanying listening above axis. The 803/804N do NOT pass stand-up/sit-down tests well at all! Although I didn't compare Matrix predecessors in my room, trusted friends who've owned Matrix802 were similarly surprised to find they too did NOT prefer the 802N in careful comparisons. (I also understand that DB Keele had a heck of a time setting up and measuring the 802N last year for his review, and found more than enough to be annoyed about, especially in the bass response...but that's 3rd-hand info) I REALLY wanted to love the 803N, as it was one of the few medium-sized 3-ways my wife would accept, but after trying Verity Audio speakers, the improvement, ESPECIALLY in coherence, midrange purity, and bass quickness and control, was overwhelming. But they did cost more.... Sorry to bend the thread. I've seen used 802Matrix for $1600/pr. Seems attractive, eh? Ernie.
Thanks Bmpnyc: I just aquired the next step up REL Storm III Sub that are helping out my B&W P5s. Thought my next step would be some N804s. I've read from some readers on Audioreview that a great sub with the N804s comes pretty close to the N802s. Anyone else??
