B & W Matrix 801 S3 and tube amplifier


I cannot find an impedance graph for B & W 801 S3.. The manufacturer states min impedance of 4 ohm and recommends amp of at least 50W. I am wondering if a 60W tube amp such as Conrad Johnson MV 60 or Premier 11A would do the job for mostly low level listening in a small-mid size room. Does anybody have experience with similar combination ? Would ss Conrad Johnson amp be a much better match ?

Ct,

I don't own 801's. I would never think of owning 801 for few reasons: 1. I don't like it's sound(which is main) 2. I haven't heard any successful demo in any room auditioned and with any amp. 3. I can't afford it or simply I would not waste money on the product that I don't like.

I fix tube, solid state and pro audio equipment part time at my dwelling knowing a large array of reasons why I get equipment to fix. After I've got equipment fixed, I'd have a very big chance of it comming back to me in few months guess why?? Because there are too many philes that think they could get arround with low-powered amp or having no idea what is impedance mismatch.

JohnnyR is a dealer that may demo or connect it for a few minutes to the unused speaker and let it go. OP wants to listen I guess a-bit longer. On a used speaker the outcome may become different when speaker breaks-in and voice coils become working at much larger dynamics and frequencies creating substantially more complex loads to the amp resulting higher operating temperatures on all circuit elements becides tubes.

If you listen to small band(no piano) on low volume levels or spoken word you can even use SET amp driving your speakers. Otherwise refer to majority of above posters.
"“This amp is a copy of the Williamson circuit from 1947 without the driver stage. Not very quick and average bass performance."

This is just the opposite of what the 801's 12" woofer needs to sound its best.

When someone asks for an opinion I like to read about direct experiences and real data. Based on the OP’s requirements – which may change, my reply was based on his OP. I figure he can make a decision based on his own.

How do we know he doesn't have a friend down the street who has this amp he can borrow. We don't. Not enough info yet.

Just remember when someone says:

Yes it should work

This implies it will work – you will get sound - does not imply it will sound good to the OP. This is subjective.

Which is why I said.

But like anything else in this hobby especially an amp it should be trialed – imo – unless the money involved is no big deal so you can sell it later if you don’t like it.

Rrog - I agree which is why I put it out there for Pvctor to consider.

Cheers
i think technical work along with testing of technical work on various components is considered to be direct experience by definition and i didn't say that it won't work. it will only for a while.
Thanks everybody for the comments. I will focus my search on solid state amp(s). So far I have Simaudio Moon w5 on my radar and I am curious about CJ MF 2500A.. Parasound seams like a good suggestion (will have to do some reading on their models) .. Are Parasound amps reliable? Do they retain value over time ? Any other suggestion for a secondhand amp in approximately $1500 - $2500 price range that would go well with CJ PV 12 and B & W 801 S3 ?
