Upgrade to B&W 804 D4 Speakers

I have never had the 804's, but I recently bought a pair of 702 S3's.  They are ok, not great.  Terrific highs mediocre lows.  I power them with a Rotel RB1582 MII.  To get them sounding great I have to turn up the volume very high.  Much to my wife's chagrin.  

I power my B&W 702 S2 speakers in a rather large deep room with two 120W tube monoblocks. Running (4) KT-120 tubes in each. They sound fantastic! Not sure why tubes can't work with the 804's, I know they have a better crossover and tweeter, that might require more power. My bass is handled by two B&W DB4s subs which give plenty of power to the low end. I love the tube sound through these speakers.

I don’t know about the D4 variant, my 804s are 20 y/o. I agree with the fact that they are power hungry. Recently I went bi-amp (all tube) and the result was night and day. They now sound the way I’d always wished they would, and I can now balance the low end to the point where I don’t even use my sub anymore.

@bzawa I don't think the 804 is a useful product. The 805 + two DB4S will give you more full mid-bass and lower extension for much less. You can use the app to pair them.

@speedysteve4 mid-bass output on the 702 can give my 802 a run for the money, better in some respect to tightness. The 804 is not on the same level. Below 40Hz, even the 802 could use help from subs.

Have you spent time listening to the B&Ws?  I get the look love.  I’ve auditioned several of their towers and standmounts because of the looks but moved on because I didn’t care for the sound long term.  I didn’t see the details on the size of your room but if you have the space I would go with Arendal 1528s with that budget.  You can buy, listen for 60 days and return for free in the US if you’re not satisfied. recommend working with a local retailer or manufacturer with a reasonable return policy so you can audition the speakers in your room with your equipment listening to the music you know my heart and love to be sure and avoid FOMO.
