Opinions: Martin Logan Renaissance 15a vs. Bowers & Wilkins 800D3

I know what I am going to suggest may work is the integrated amp from McIntosh the MA12000 with a tube preamp built in and 350W per two channels. Your thoughts. Would this work well instead of using separates?

@farne230 should be fine.  

I appreciate every one who posted, I ended up purchasing the B&W 800D3 used from a local dealer at a good price, compared to what has been listed. Regarding the rest of the equipment, the dealer suggested Mac MA 12000 (new) or MC 611 or MC1.25 mono-Amps, didn't provide cables just a budget 7,000-11,000, Hifi Rose RS250 streamer, Mac MEN 220 room conditioner, Audioquest Niagara Power Filter and Quadraspire (stands).  I also would like a cd player and am/fm tuner (of course Mac has these products too). Any suggestions will be most appreciated. Thank you

Not sure about a tuner recommendation... I stream through Roon for radio stations so don't use one.

I would recommend a separate transport & DAC instead of a CD player. In regard to transports, a lot of people are using "Projects" TOTL or "Jays". As far as DAC's, I like the Musetec DA005 (great player / especially for the money), but there are a ton of other good ones out there as well.    

Good choice with the B&W 800D3's!

I "almost" purchased a pair myself when they were first offered.

At that time, I had been listening to them during scheduled auditions at my local Hifi store. And at the end of the initial session, I asked if they could possibly swap the gear to a different amplifier set. Instead of the (2-channel), "Classe" amplifier currently integrated with the B&W 800D3.

 My sales rep. (Whom I have come to trust over the years). Informed me that these speakers had been actually, "Voiced" with the "Classe" amplifiers during final development in England. I was a bit surprised at this. Thinking at the time that "Classe" was in my mind, a bit of an "Underachiever" insofar as these things go.

But they did the gear swap before my next session. With a much more well regarded. "And expensive" set of mono-block amplifiers.

And I must admit that the B&W's sounded just more well-rounded with the (2-channel) "Classe" amp instead

So you "may" want to try one of the "Classe" offerings...

I do not remember the exact model. But I do remember, "new" it was retailing for ($5000-$5500). And this was a few years ago.

And I believe I remember him mentioning that it was a (2 x 200Wpc.) amp as well.

Good luck!
