B&W 802 N vs. D


I apologize in advance since this is probably an old question, but can someone summarize for me the differences in the sound of the 802 N and 802 D? I am wondering if the D's are worth the extra $$ they go for.

Bombaywalla:

Do you think my Theta Dreadnaught II would be sufficient to cope with the issues you mention, or would it be more like the Classe in design?
The truth of the matter, Diw, is that I don't know as I have never heard a Dreadnaught II driving an 802D.
after reading an online review in the Ultimate AV mag, I seem to be in 2 minds (of course, this is just a review & words cannot describe how the actual amp-speaker interface will fare; only listening can prove/disprove that). I've cut & paste from that review below:
Into an 8ohms load, with five channels driven, the Dreadnaught II clipped (1% THD+noise) at 192W per channel at 20Hz and at 189Wpc at 1kHz (215Wpc with two channels driven at 1kHz into 8ohms). Into a 4ohms load, five channels driven, clipping occurred at 228Wpc at 20Hz and at 227Wpc at 1kHz (255Wpc with two channels driven at 1kHz into 4ohms).
isn't clipping supposed to indicate the point where max power has been reached? so, why didn't the amp's power increase substantially (double?) into a 4 ohm load? There was a marginal increase only.
With the Theta, however, the distortion increases gradually as power increases. At 2% distortion, for example, the Dreadnaught II will put out 257Wpc into 8ohms and 341W at 4ohms (two channels driven at 1kHz). The amplifier is able to double its 8ohms rated power when the load drops to 4ohms, but at a distortion level of 7.4% (450Wpc, two channels driven at 1kHz). It should also be noted that the distortion in the Dreadnaught II at very high power levels is higher than we measured for the original Dreadnaught.
the levels of distortion seem disturbing to me but maybe I'm being too picky? Or, is this amp designed specifically for HT & these levels of distortion are OK for HT use?
I would certainly not be successful using this amp to drive my Scintillas! They'd burn up in a short time!

What does your listening tell you? Does the Dreadnaught II cut it?

By the way, I enjoyed looking at the pictures of your Scintillas. Now that brings me back to another era!
Thanks for you kind words, Diw. I love those speakers. they are a very hard load to drive & they make your 802D, in comparison, a very easy load. ;-)
Yes, they belong to a bygone era (that, according to me, was when audio was a growing market & there was more dedication in the manuf than there ever will be today) - it's an oldie but a (very) goldie.....

Bombaywalla ..We all know that the 802 needs power,old old news,,.....
you are quite the antogonist, Missioncoonery, aren't you?? on the prowl looking for a fight....
Ok, so you know that B&W speakers like power. So, which kind of amp would be suitable for this type of speaker? When you listened to this speaker, which amp or amps did you listen to it with??
Power, as your clever self would know, has 2 components & you can get high wattage increasing either or both components. Which of these 2 components of power seem to be more important for B&W speakers in your opinion?
Bombaywalla..I have no idea what works with the 802D..and dont care..I have no interest in them or the process in trying to make B&W speakers sound good..No im not looking for a fight,just thought your writings were silly and unimportant to be honest..but as stated enjoy those B&Ws..

my post might be unimportant to you but you are not the only one on this forum. My post might have meaning to others interested in this brand & those interested in making these speakers sound better. It's OK with me that you do not like B&W & never will; you've made that clear w/o mincing your words. Fine w/ me; no offence taken.
I also think that your mind is shut closed.
Further you cannot read! Read my original post & tell me if I still own B&Ws.
You have dodged my power related question completely that alone has told me a lot about you!
"You have dodged my power related question completely that alone has told me a lot about you!"

I have no imput on how to make B&W speakers sound correct,not dodging anything..Simply just dont care...Back to the original poster ,go listen and judge for yourself..We are done with this,enjoy
