Bosendoefer speakers
Beautiful finish, nice sound, unfriendly pricing (expensive). Very rich sounding, as in harmonics... I heard them with A-Note electronics (quite good) a class A SS (better). Unusual design. 
Heard the $325000 Acapella's Sphaeron excaliburs?
Friend of mine once said, "A poor consumer is fortunate because he/she has nothing to lose because he/she has nothing to buy (with). A man on a budget is ultimately limited by that budget..." Which is one way of looking at this tantalising product... 
About Lugnut -- Patrick Malone
I only met Pat briefly and virtually... after reading the news I have a feeling of irretrievable loss and yet, I also feel a (frightening for me) sense of calm; Pat's new life will be good and peacefulThank you Pat and Barb for coming into our liv... 
What to put under Avalon speakers?
Glai: Of course there's a difference intreatment between bottom ported and sealed spkr designs... In the first place, the bottom ported model (should) have factored the distance between port & floor into the spkr design -- hence, for example A... 
Velodyne DD: 10 or 12?
80 Hz is a good point because it's around there that we start losing localisation making the blending with the main spkrs easier. Also the high frequency sound fm a 12' subwoof driver is not linear (that driver wasn't made to tackle midbass).As to...

God bless you Pat, Barb, and all the tubes operating, and the musical tunes and yr love for one another... 
Good Tube amp to drive B&W Matrix 801's
As above, you'll need extremely high energy amps to do the job well -- tube or ss. As noted above, you'll be easier off with a transistor than a tube -- if only considering the cost of tube watts.Is there a conversion factor for tube watts vs sold... 
10k 300B single ended amp, what should I choose?
Indeed, you'll need a very hefty 300B to reproduce large orchestral works with ease especially if you want one amp to drive the spkrs full-range (I would suggest you use another amp for the bass).DIYing is an excellent option, as suggested above. ... 
300B tube recommendation for SET amp?
Dogpile, you might want to consult Thorsten Loesch'scomparison, another comparison by an audio mag (worldaudiodesign) hereand finally, an overview by enjoythemusic here.Cheers 
Vibration control question....
OK, Muskrat, good point. I would try placing the cdp directly on the granite; I wouldn't decouple the granite from its support with vibras. I'd try the vibras under the cdp and compare to cdp direct (above).Given its mass, the granite's resonance ... 
A brutal review of the Wilson Maxx
It's too easy to criticise any spkr based on some (often incomplete) data as it's easy to condone a spkr because "I like it" and use the same data to support that view. In reading Mr Hardesty's article it seems to me that, in part, there is an att... 
Vibration control question....
Why not try jadem6 directly (sorry jd)? We've all played around with vibration & its control -- BUT I believe jadem6 is one who has reached PhD status on the matter:) 
Upgrading Preamp - How About Some Suggestions
I would also see the CAT as an option for punchy sound. A used one of course -- the CAT is expensive new.Another alternative is to borrow a transformer volume control and try that out (with a line source). Check if that rocks yr boat... 
Single Driver Horn vs Multi driver efficient spker
Gmood1 I have "auditioned" a pair of Orions someone made. They were in a largish room ~300sq.In short they do sound a lot like planars with dynamics as you say. In fact they were outstanding. The ones I heard were driven by 8 channels of amplifica... 
Any experience with Troels Gravesen's DIY designs?
I have. The 2.5 & the Acapella. The second I liked enormously. I didn't diy these myself, so I can't give inside info. ASAIK, the Acapella guy followed instructions to the letter (using the scan tweet).What would you like to know.
