Primare I30 and B&W 803D, enough power??

Rotel is good, but the "dual mono" Primare I30 is in another league, and will not have a problem driving the B&W 803D's in your apartment.. Low to mid level listening will be much better with the Primare I30. 400 watt mono blocks are not necessary for B&W 803D's in your apartment. In your apartment, my choice would be something solid state with very large power supply, and is class A with 100 watts per side... low to mid level listening does not get any better with this type of amp...IMO, anyway.

I would suggest addition of another amp for bass drivers, i.e. trying bi-amping. Natural choice in this context should be the Primare A33.2 (120Wpc).

Having pretty extensive experience with B&W (not exactly 803D, but smaller 803S - used to own them for 3 years), I have not impression that I30's current capability is sufficient for always power hungry B&W. My former pair of 803S sounded properly with Rotel RB-1090 or Parasound A-21, much bigger amps than I30.

Demianm: 20m2 is a rather smallish listening room. I hope your 303D aren't too big for it. Are you planning to accoustically treat the room? I suggest you look into that.

I'm not familiar with the I30, but owned Rotel RB1080 and B&W 804S, so similar but smaller and with the aluminum tweeter. I didn't like the trebble of that combo and replaced it for a 2 x 75 W tube amp (McIntosh MC275) and love the combo. Yet I'm experimenting with active biamping.

So will the I30 drive the 803D? Yes, no question. Will you be getting all the speakers can deliver? Likely not. Maybe you go step by step.

Thanks for all the replies. I kinda know what 100W RMS sounds like, but many people insist that 100w is too weak to drive these speakers. I know very well that 400w will give me lots of clarity at concert-levels when demoing the equipment to my friends with rock music, but the other 99% of the time I will be listening to jazz and other soft music at levels to maintain a good neighbour relationship. Right now I have a Rotel RB1062 at home and I am satisfied with the volume levels on my 90db speakers. It´s the harness and lack of soundstage that I cannot accept.

Space is also one issue for me, I would like to avoid separates for now so that my living room more or less stays looking like a living room.

Someone pointed out if I had any room treatment, well yes, there are panels at first reflections, and behind the speakers, and also 3 bass traps, helped a lot.

I am a bit hesitant to pull the trigger because I cannot try the Primare at home, and buying and selling it can be a bit costly, resale for the Primare is not so easy as another brands.

Got a Tact M2150 for my 802D's and it sounds wonderful!
Should do the same for your 803's.

Can be had in your price range used. (If you can find one)
