Best amp for B&W Nautilus 804? Looking for advice.


Howdy,

I own a pair of B&W Nautilus 804's and I'm looking for a new (used) amp/preamp to drive them. I'm currently using a Classe CAP-151 which is adequate but I'm looking for more. Looking for a broader, deeper soundstage and a live, real sound (at least as much as my budget will allow).

Right now I'm looking on the used market for one of these three set-ups: 1)Classe 47.5 Pre / CA-301 Power; 2)Krell KRC3 Pre / FPB200 Power; 3) Krell KAV 500i. Any other options in this price range?

Don't have a krell dealer in the area so I can't audition. Hoping anyone familiar with that equipment will offer their opinion.

Thanks all, John

I have the 804's and they need solid state. I first had the 804's paired with 2 different conrad-johnson set ups. The CAV-50 no detail, then the prem.11 better but just not there. I now have the 804's paired to a Mark Levinson #383 and they came alive. Great detail. The 804's voice so well they bring the best out of good solid state. I have the c-j set up running Spendor 2/3's and that set up sings. I love music and I like both solid state and tube's. E-Mail me if you want to know more. Peace and Good Listening.
I too would like some help. I have a pair of Matrix 804's. I have been in the market for a new power amp. Presently I am using a Carver 705x (125 wpc) 5 channel as a power amp with an AI3 pre-amp. I tried the Transcendent compact 150 wpc and did not think there was that much difference. Maybe I have tin ears? My last hope for a new tube amp in my price range is a Rogue I think. Used there may be others. I would like some advice on other amps ($2000 new or used). Belles, used krell, I don't really know. I like orchestral and I sometimes get up to the 90 db range or so for short periods. BTW somebody from customer service at B&W told me not to even think about a low powered tube amp or even SS at less than 100wpc. Any thoughts out there to confuse me further?
I know two dealers from two different areas who both found that Primare(from Norway, I think) equipment really opens up the 804s. I thought this was significant because Primare is relatively new and unknown on the scene here in the US, yet both these dealers stumbled onto the same conclusion after trying lots of other stuff. Might be hard to find, but a very good value and built like a brick craphouse, and it looks great too. Best of luck.
