For the moment using two Electrocompaniet aw250 Bridged. with Ec 4.8. Emc1 up, nordost (from frey-Tyr)

Thinking about MCintosh, pass labs, Adyton,

hoping to get some respons from guys having the 800 Diamonds, or have experience with different setups, sound characterstics of the different brands used on theese loudspeakers.

I own B&W 802 Diamond and also have been a long time fan of B&W speakers. Also, I checked many, many amplifiers because these speakers are truly power hundgry.

My choice was a pair of Spectron Musician III Mk2 fully balanced monoblocks and along with my Joule-Electra LA-300ME preamp provide with the heaven. Pure heaven. Only having these power amplifiers I could hear (for first time?) real symphonic and orchestral music - the closest to true acoustic experience I ahve had with other speakers/amp compination

All The Best
Accuphase amps work very very well with B&W speakers. (If I am not
mistaken, Accuphase amps are tested on B&W speakers from the 800
series.) I've heard your speakers in an all Accuphase system (A-45 power
amp, C-2810 pre and DP-700 cd player) and the combination was
marvelous, outclassing much more expensive Gryphon and MBL system
(which I have heard in the same room).

To answer the original question, the A-46 power amp (45 class A watts into
8 ohm and doubling down till 1 ohm) will drive your speakers very well. The
A-65 (60 class A watts into 8 ohm and doubling down till 1 ohm) will do
even better, and if money is no object then go for the A-200 mono-blocks.

As other have mentioned already, the 800 diamonds do not need tons of
power, any quality high-current amp will make them cry like babies.

Good luck and keep us posted!

Hello all,

I am setting about finding matching amplification for my 802N. I have been playing around with amplification.

I have a MAC6700 receiver which offers 8, 4 and 2 ohm settings. On the 8 ohm, the bass is the most defined but the highs are a bit too forward. On the 4 ohm setting, the highs are very nice but the bass is toned down. I am single wiring the 802s as my receiver features single terminals.

Some things I have noticed: When I run the single wire to upper inputs on the speakers the highs are better defined. When I run the single wires to the bottom speaker inputs, the bass is stronger and the highs are slightly recessed. I am using B&W jumpers.

Another test I ran was to remove the jumpers and connect the MAC6700 at 8 ohm to the woofers and amp the mids/highs with a second high powered stereo amp. This has been the best result so far in terms of imaging, transparency of soundstage and bass definition.

So, I am wondering if I should try:

-running tubes to the top and ss to the bottom
-powerful tube monos only
-powerful ss monos only

I do like the sweetness of the MAC6700 but I feel there is more to be gained by fine tuning the amplification.
Pass Labs X600.5 is a very good match. I adviced it to a client of mine. He is very happy with it. It makes the low freq. a lot more powerfull. Speed is also important for the 800D. After the 800S I also thought about the 800D. But I stopped cause of the filters of the 800D. For the absolute sound a very deep and wide stage makes listening to music so much more fun and emotional. I had hoped B&W had improved this. I am affraid this Always will be there weakest point. In the world of the best highend an extreme deep and wide stage is a pre. Wenn it is not there you miss too much.
I have 800 diamonds (d2), any thoughts on mc1000 mono blocks?
To be used w oppo 105 and arc ref5se.
