Overall
What is my overall opinion, you might ask. Thing is, this is difficult to decide. Sometimes these speakers amaze me and sound totally convincing. Other times they sound thin, flat and plain uninspiring. They perform at their best with real music, acoustical instruments and voices. Blues and jazz can be stunning. Electronic music fares less well: it quickly sounds electronic as well. Smooth jazz often isn't smooth on the 800D's. Often times, with less well recorded CD's, these speakers sound nothing like their hefty price tag presumes. Of course you could argue that the source is to blame. Garbage in, garbage out, right? Well, I can't disagree, but I listen to music for my enjoyment. Not to be punished for having bought mediocre CD's. I guess that this is the price you pay for having state of the art monitors. After all, that's what they are: studio monitors. They have been developed for making music mixes whil listening loudly. The most important factor was for them to be able to play really loud while having vanishingly low distortion. That goal has been achieved. My initial listening was with Transparent cabling allround. The speaker cables are Transparent Reference XL's and while thay aren't mushy or overly smooth, they are very subtle and forgiving in nature. But even with these cables the speakers sounded analytical. I swapped to Cardas Golden Reference but that was too much and it resulted in sloppy, slow bass and less articulation in the lower midrange. As a whole, these are certainly among the best speakers I have heard. But they are a bit too fussy for me. Also, I don't think that they perform optimally in my room. I suspect that these speakers need an even larger room. To further test this, and to make the review more meaningful, I compared the 800D's to a few other speakers.
Compared to Nautilus 804
A comparison was easy to make since the 804's are permanently setup in the cinema room. Immediately after connecting them up it was evident that the 802D indeed has a dark balance. There are people who find the N804's treble brittle or hard. I'm here to tell you that this is nonsense. They may have heard new speakers, bad equipment or there may have been a mismatch going on. But the Nautilus tweeters are certainly never harsh or brittle. This was again evidenced when comparing them to the Diamond tweeters. The N804 was at once more open and airy but also a lot more fluid and gentle. The Diamond could be said to be more accurate and more dynamic but it was also ruthless. The Nautilus tweeter by comparison was much more forgiving and made me think of the Magnepan's ribbons. of course the latter are even more airy and open but still, I very much like the Nautilus tweeter. So, have B&W gone too far? Have they traded musicality for accuracy? I'm not sure. I have also had the 802D's in the past, and their tweeters, if memory serves, were very fluid and in fact sounded less like tweeters than those of the N804's. They simply made music and never made themselves known. So what changed in the 800D? Perhaps a combination of the filtercomponents, lower tolerances and maybe the conscious decision to make the 800 a more honest speaker. But I digress. The N804 not only sounded airier and more subtle, it was more engaging overall, as if it was completely run in and the 800D came freshly out of the box. But these 800D's were already 6 years old when I bought them. They may have been out of duty for a while, while the previous owner enjoyed his new speakers but still, I made sure that I shook them loose (poor neighbors) and listened to lots of music over the coarse of two weeks before starting on this review. Of course the N804 had less bass, but it coped well, its bass being more agile and quick and also more tuneful. When combined with the Rel subs, the 804's could really shine. This was a sound that I could live with if I didn't have Magnepans. The enormous price difference at first didn't seem justified. But the midrange was where the N804's had to bow to the 800D's. Where the 800D's had an immense soundstage and managed to image completely free from its enclosure, the N804's were narrow and 2D in comparison. You should know that I compared the N804 to many speakers and always have they sounded utterly spacious. This only goes to illustrate that the 800D's are really special in that respect.
Compared to Magnepan MG3.6R
The Magnepans are a tough act to follow. Even for 800D's as it turns out. Again, my room may be to blame too, but the Maggies just sound way more detailed, are more open, faster, and more articulate. Their treble is so much more open and delicate that it is scary. They make the 800D's treble sound dull and muffled. They also manage to do this while avoiding being too clinical. In fact, their treble is much more smooth and fluid than that of the 800D. The Maggies may well have too much treble energy but even so, the quality of the treble is just plain difficult for regular tweeters (diamond or not) to follow. The Maggies' midrange is less stellar than their treble in that it posesses a slight analytical quality and can be thin if ill-matched or ill-setup. Still, the Magnepans manage to win me over for their midrange when compared to the 800D's. It is much more refined and subtle but more importantly, it doesn't have any apparent coloration. The FST unit in the 800D's has a definite character that makes it stand out sometimes. The Maggie's midrange is more embedded in the whole and in fact does't make itself heard at all. It is just very well integrated. This is the advantage of having no enclosure. The bass, finally, is where the Maggies have to bow to their masters. For a full range magnetostat, they have good bass. It is fast and articulate, much better in fact than that of its predecessor, the MG3.5. But it has no real power and doesn't go very low. If combined with good subwoofers, they can perform well enough but I'm afraid that after you've heard the 800D's you will never be satisfied with the bass of any other speaker ever again. Also, while the Magnepans have similar soundstaging capability in that they image very widely and have excellent focus, they don't image as well in the depth field. Here the 800D's are clearly better.
