Bowers and Wilkins, 801 D4

One fantastic speaker you have overlooked the MBL Loudspeakers 

they not only radiate evenly but their direct connection to the source allows parts of the recording lost in most other speakers I have 2 friends and my brother sold his 1 year old Shasha daws , forthe MBL floorstanders under the 101s 

the efficiency rating is deceiving since it radiates equally the same spl level all around the room ,and pretty much even off axis it has a sweet spot a Fantastic Loudspeaker ,every one of their models has the same carbon fiber tweeter and midrange. I am hoping to buy a pair next year they are that good.after 3 decades I found a true reference , a high current Amp is all they ask .

B&W’s you just hookup and maybe spend some time positioning. The Wilson’s require a tool kit, Sun dial, abacus and loads of patience! No clue why an Audiophile would invest in them…Engineer, Rocket scientist, maybe but wayyy too much going on with their upper end speakers IMO…

Both speakers , are “cliché “ speakers with a great marketing plan , very knowned  ,but I don’t like them ,because (for me ) they don’t give the natural sound , perceptibility , you don’t go “into the music” : you miss the feelings and empathy… that’s mine opinion … there are many speakers that sound much better : but you have to make the effort to look for them keeping in mind your favorite music/genre , and it must match with your other components…

Hi, well i have , an Esoteric K01-X cd player, Audionet Humboldt integrated amp, Wilson audio Sasha mk1, all cabling is MIT HD 60, dedicated room 12foot by 23 foot, firing the down the length of the room, music is mainly  prog rock, but anything guitar based,  ish,

will my amp have enough grunt for the B&W, and is my room to small for them, 

Also i can't find out how  many Amp's it puts out, thanks andy

I had original 801s for many years when they were freshly launched (1995?) and I was very happy.  Both the tweeters failed after around 7 years, not in a user-induced event.  I replaced and sold on at that point, replacing with ML CLX Anniversaries.

Your amp has plenty of power to drive either speaker well but looking at its output into 8 and 4 ohms, it could benefit from a stiffer power supply.
