B&W 805S & BAT VK300x SE Integrated. Synergy??

I have the above speakers(805S, NOT 805 Signature), hooked up to Sony SCD-777ES SACD Player with Acoustic Zen Matrix Reference II interconnects and Satori speaker cable. I listen to all sorts of music except classical. I love the speakers and changing them just yet is not an option.

The BAT VK300x SE Integrated is the amp I'm eyeing, it beat out the McIntosh 6900 and Gryphon Diablo to my ears. This is the amp with the 6H30 supertube...fast, neutral, dynamic, beautifully layered, incredibly transparent and great bass.

The highs however had a slight edge to them, which might be because of the tube used.

Since the B&W 805S can also have a tendency to sound a tad bright in the highs, I'm wondering if the BAT will exacerbate this effect.

Sadly, I cannot audition my speakers with the amp.

So I ask you, can anyone articulate the sonic character of the 805S and perhaps shed some light on any synergy issues that I might want to watch out for.

The other option is to get the 6922 tube version BAT integrated but I don't want to exercise it unless the SE is a lost cause with my 805S.

Another interesting spanner has been slung into the works by the CD player. Though I love my Sony SCD777ES, I am in lust with the looks and sound of the Cary 306 SACD player (which apparently uses the same transport as the Sony SCD-1 flagship). Plus Im intrigued about how an upsampling player can rejuvenate my old collection of CDs.

Even though I heard the Cary for just 2 minutes it sounded decidedly different to my Sony player.

Has anyone paired this player with the BAT integrated and what were the results. If not, I'm also open to informed judgements about what I can expect from this union, from people who may happen to know the character of both these devices.

I had my 805s bolted to the plate but tried setting them up on 3 brass points.
I still use the bolts, slightly tightened, to keep them safe.
Audio Oracle. good amps no doubt but I am looking for a hybrid, with the texture and wetness of tubes. So Plinius is probably not for my tastes at this point.

I own the 300XSE amp, and I can assure you it won't sound shrill or overly bright, as long as you partner it with the right speaker cable and interconnects. I use Audience AU24 throughout my system, which includes a Magnum Dynalab MD-102 tuner, and an Electrocompaniet DAC (linked to a Philips 963 DVD/SACD player) all feeding into a pair of Tyler Acoustics Linbrook Signature floorstanders - the sound is gorgeous (especially with the tuner on good FM stations) - very layered, almost so dense you feel like you're walking among the band members if you can force yourself from the sweet spot :) Stick with the super tubes - they won't let you down. Regarding your question about replacing the tubes, an alen wrench is provided with the amp, and the two tubes are easily removed (remember to avoid touching them with your bare hands). Good luck.
I disagree the Plinius is very tube like, don't discount it before you here it. Also for the record the BAT isn't very tube sounding,but it is excellent, you should try to listen to one before you count it out it is really musical.
Denelle, thanks, interesting info. I'll be using Acoustic Zen Matrix Reference II interconnects and Satori speaker cable. I'll find out hw they sound with the amp this weekend.
