What does more power do for Magnepans?
Pa1- I really do think you will be surprised at how relieving your amp of having to reproduce bass/mid-bass can clean and open up your overall sound. Can you find a dealer that will let you audition one for a week or better? That would give you ti... 
What does more power do for Magnepans?
Your 9200 has pre-outs and 200wpc. If you were to purchase a Plinius P10(also 200wpc) you could bi-amp very simply. Magnepan offers an optional bi-amp x-over for the 3.6/R, and I'll bet one is also available for the 3.5. You might give them a call... 
Bose 901...really
It's been my experience, and my point in this discourse, that they have never sounded like live music by any stretch of the imagination. That(live music) is my reference, and will always remain so. I'm much more a sound technician/engineer than an... 
What does more power do for Magnepans?
For an understanding of audio output in db, and power requirement, read this:(http://www.axiomaudio.com/power.html) It would be nice if doubling the perceived sound only required doubling the power. The least I've powered Maggies with was a slight... 
Tube rectification
If the rectifier circuit does not have a feature to slow the high voltage from coming up to full: The life of your tubes will be severely shortened. A tubed rectifier circuit allows the tubes to slowly warm up to full operating temps. Because ther... 
Bose 901...really
I don't think I've read any ratings on those smallish woofer systems that claim much below 40-50hz. Nothing in what I consider the bottom octave. And you are absolutely right on two counts: they still beat their hearts out trying, and that's why s... 
Bose 901...really
But none of those current speaker designs are trying to reproduce everything from 20Hz to 20kHz with that same one driver. The laws of physics just don't allow it without distortion. Perhaps one day the 901 will be produced with a cone than acts a... 
Bose 901...really
Eldartford- I missed that last sentence. Hey- If it works, and you're happy: don't change it!! Just build your airplane around it. Maybe if you keep it in the corners, your wife won't notice? Tell her it's an acoustic treatment to eliminate spurio... 
Bose 901...really
Good old Amar's first concoction was the "2601" and had that many speakers(26, or was it 28?) arrayed on the surface of what looked like 2 segments(eighths) of a huge grapefruit that sat in the corners of the room. Of course, the speakers were the... 
Where can I find a RS1b bass driver?
I've bought a lot of parts(cones/surrounds) from Millersound. A very knowledgeable and pleasant person to deal with! He would be my recommendation as well.

Hi Eldartford- I envy you for your soundroom. If I had a room that big, I'd be torn between using it as a listening room, or rebuilding my cars/bike in there(too many loves, not enough room). I've a number of recordings that were done personally, ... 
Extreme Midrange Bloom
Those teflon V-Caps do sound intriguing. AudioCap has teflon/tin foil caps as well. Same manufacturer as the MultiCaps I recommended. These caps are the creations of one Richard Marsh(the founder of Marsh Sound Design). If you know how good his el... 
Getting back to members on passive vs active lines
Addendum: SS output impedances would be more stable than tubed. My CD player employs no buffers at all. Here is a review, and measurements comparing the outputs of two Cary CD players, the same except for one employing a tubed output section. Noti... 
Getting back to members on passive vs active lines
The output impedence of your CD player will vary with frequency. IE: My BAT VK-D5's output impedence measures between 880 to 910 in the middle and high freqs, but goes to 8475ohms at the lowest(single-ended). Balanced- it's 980s to 1200s, and 17kO... 
Tube amps have a signature sound
Bigkidz- If you bi-amp correctly, you'll never go back. For instance, read this: (http://www.avguide.com/products/product-1672/) Click on the review. I'd been using a Dahlquist DQLP-1(slightly modded over the years) since 1981 with great results. ...
