BW 800-805 D3 series VS 800-805 Nautilus/S series

Using the B&W 805 Signature (Tiger Eye Finish) as rear speakers in 5.1 system driven by Bryston 6B SST. Had some time recently and repositioned them removing Avalon Indra's as front R/L driven by a Rowland M312 (way more power than they need) with the addition of a Kharma CeSb 1.0 Sub. Was amazed at how well they held their own. Nothing can replace the coherence and imaging if the Indra's, but; the dynamics & detail was all there with B&W 805S's. Totally underutilized in my system for sure.

Yeah, I currently have the N805, 805S and 804S. The more generations B&W pumps out, the more it depresses the market price of these amazing speakers. Also, the woodwork peaked around this time imo. 

The 805 Signature has held their value amazingly well.  I believe they retailed for $3500 new, and they still command 75-80% of that on the secondary market for a nicely-preserved pair.  And really, even the N805, 805S and 804S still sell for a healthy percentage of original retail.  In fact, we could name quite a few well-known, highly-reviewed, semi-mainstream audiophile brands that wish their products held the same percentage of retail.    What did the N805 cost new at retail, $2500?   And today, they still sell regularly for $1500+, correct?    That's 60% of original retail for a speaker introduced to market 15 or so years ago...not too shabby.   Correct me if my math is wrong about those original retail numbers...

I have 804S and 803D and find the smaller 804S almost as engaging. I think if both had the same crossover components, the differences might be even smaller. The 804S uses lower grade polypropylene couping caps to the midrange and tweeter, while the 803D uses Mundorf silver/Oil. I recently modded my 803Ds to Silver/gold/oil for both mid-range and tweeter and it makes quite a bit of difference. So I wonder what the 804S would sound like with those Mundorf silver/gold/oils and the upgraded resistors. Note also, that B&W used different series resistors on the tweeters to adjust the high frequency levels and this may impact how you hear them.

The used prices are very strong. 1500-2000 for the n805 and another 250 respectively for the 805s. The 804s goes for about 2500-2700 in mint condition. This speaks to their overall excellence. I hope to hear more about the D3s.
