I remember seeing those amps in catalogs in the early 90's. They are really nice looking. Don't know any more than that. Do you have a pair of can you get a good deal on a pair?
If you are looking for a moderately priced amp that is up to the challenge of higher end B&W's, check out the Crown K2's. They are pro amps and you will be able to get most of your money back out when you upgrade (you will upgrade, we all do, just accept it). :E- Bottom

The specs say they will "double down" to 2 ohms-1000 watts! They should drive just about any speaker you hook 'em to. Go for it. I'm only guessing , but they should 'encourage' the B & Ws to put out a decent effort.Lee

Yes, sorry should have said that it will be 803D or 802D - I have not decided yet. I have seen these amps online, but they hardly ever come up for sale outside of Japan so I am looking forward into the future - I would like to find some in Europe because the voltage will then be 220v like here in the UK.
In the short term I am thinking about the denon POA-A1HD running 5 channels in bridged differential mode. This would be controversial I know, but if i do manage to get either of these amps then the A1HD could be used for centre/rear etc and hopefully should integrate well with the mains.- Bottom

I did not read the specs on the Denons. If they double at 4 and again at 2 ohms they are what you are looking for.- Bottom

According to the website:
802D
Nominal Impedance 8Ω (minimum 3.5Ω)
Crossover frequencies 350Hz, 4kHz
Recommended Amplifier Power 50W – 500W into 8Ω on unclipped programme
803D
Nominal Impedance 8Ω (minimum 3.0Ω)
Crossover frequencies 350Hz, 4kHz
Recommended Amplifier Power 50W – 500W into 8Ω on unclipped programme
If I am reading this right, it shows that infact the 803D is more difficult than the 802D - is this right?- Bottom

Not quite!
Its not only a matter of which is the minimum impedance, but the whole diagram (impedance/freq). It depends on phase shifts etch... I believe that 802D is more difficult load than 803D.
To give you an example 804S have minimum impedance of 3.0 ohms. Still they are an easier load than 803D or 802D.

Actually the 802 dips to 3ohms for much 100-1000h range so yeah it's quite a difficult load. Phase swings quite a bit as well.
But from the website the denon seems to be 1 ohm stable so that and the fact that your getting japanese build quality would be enough to sell me on them assuming the price is good :-)- Bottom

I've listened to the PMA-S1 with B&W 805S. PO series are dedicated amps. PM series are integrated amp. Not the same devices, but I figure both are their high end of the spectrum, so there shouldn't be such a difference in sound. Either way, if it matters to you, I was very impressed. Very very transparent and smooth. The lower I went down the PM line, the more the music seemed to be a tad bit colored. My instant assumption was that most people buying Denon's flagship amp or integrated amp would be powering speakers of the same caliber and would want the music to be as pure and transparent as possible.
Though still focusing on the PMA line, don't mistake the Denon Premium line with the regular Denon AV receiver products. I really underestimated that line cause it was from Denon. In the past, I found Denon receivers to color the music too much. Sounded nice, but not true. However, the PMA-S1 sounded amazing real. So perhaps the PO-S1 would give the same performance. I know kind of out of line, but I hope that helps.B&W 804S/Velodyne SPL-1000R/Anthem MRX720- Bottom
