Tube vs Solid State

Sounds like a cool idea. .I have a cary sli80 and a hegel h360 so I can switch it up from time to time. .speakers are Thiel cs3.7 and the best combo I ran through them was a mcintosh mc7270 with the cary sp05 preamp. .it really work the speakers up!  I'm thinking about some tube monoblocks as well.both ayon and carver put out some powerful tube amps..bit pricey but I I'm betting pretty spectacular. .best of luck. 

I've heard some awesome things about the Bricasti M28 Mono Blocks paired specifically with large B&W loudspeakers.  No personal experience.
As far as preamplifiers are concerned, in my not so humble opinion, there are only preamplifiers that sound worse than the Sutherland N1 none better.
Good luck

lots of good suggestions so far, so here's my 2 cents ........

Rogue Audio, put a pair of their Apollo 'Darks' up against your B&W's, plenty guts / bandwidth to drive your bottom end and not soften your top end. I'm using their smaller siblings (M-180 mono blocks) to drive my Revel Studio 2's with plenty of authority.

Your speakers will absolutely wake up with Bryston 7B or 28B power.

I know someone who drives his BW 800s with  krell monos and uses 2  x velodyne subs - sounds great

I personally prefer tube amps but I have enjoyed listening to solid state amps also so I recommend you get whichever one brings you the most enjoyment when you listen to music. The bottom line is to enjoy the music. 

Hi laltik.  If you enjoy the sound that top-shelf modern tube gear can provide (an ideal and real combination of ambience and transient speed), are leaning toward monos (good for you!), want an amp that can drive any load and in the process deliver the fullest of real base then you and I have much in common.  Without getting into the significant details of my hunt, I'll just go right to the results of my kill.  For me it was the perfect choice and based on the constant feedback of my fellow audio hunters in our local hi-fi tribe - I did kill it! 

I landed the Octave MRE 220's with the Super Black Boxes.  For and well above their price point they are unmatched.  Effortlessly driving any load; providing a soundstage you can drive around in and get lost; leaving nothing wanting in the bass from start to finish; giving every instrument its own space, sustain and decay with unmatched realism.  Over and above all of that the reproduction of the human voice is exactly that.

From one passionate hunter/gatherer to another, in this vast forest of countless audio animals, my kill was well worth the effort.  My feast is always plentiful and is enjoyed by everyone who drops by.  All the best in your hunt.  Good luck!!!

@rspyder, thank for your recommendation. Man, the very notion of HP700 and MRE220 pairing sounds pretty heavenly.  

May I please know what speakers and preamp you're using with MRE220?

Cheers!

Lalitk,

I have a pair of Audio Research Reference 610T's for sale that will meet all your needs and then some.  The following review sums it up very well.

Larry,

Thank you for your offer. I end up auditioning the MAC's, more than likely I am going to end up keeping them. 

see if you can get impedance vs. freq. curves from the manf. of your speakers (or the drivers) before spending a lot of $$ and time trying the biamp route

also ask them about bi-amping
