Thanks soix, I used those Herbie's gliders on a rack that I built with my daughter for her system. My speakers sit upon custom Silent Running Audio platforms for isolation with completely flat bottoms. I'll talk to my dealer Jeff to find out if it would be okay to drill into the SRAs to do the same thing. That would make it much easier to move the speakers around. I like that!
audphile1 - My Boulder L3AE line stage was built in 1990, and was one of the first Boulder Amplifiers products. It received excellent reviews at the time and still does if you look around. I picked it up as a slightly used demo from a Listen Up store back then for $1,250, but the retail was $3,500. The salesman was a friend of mine. Mark Levinson was in their heyday back then, so I had the Boulder inserted into their top system being demonstrated. I could not hear any difference betwen the Boulder and Levinson preamp. This revealed to me that the Boulder did not impart its own sound on the system. About 5 years ago, I took it to Boulder Amplifiers that was now a much different company manufacturing products so expensive that I could never afford. The guys their hovered over my L3AE and jumped on the opportunity to replace the caps. I've been using this line stage ever since.
My TW-Acustic 300B amps are made one at a time by Thomas in Germany who owns the company. I've met him a couple of times at the RMAF shows in Denver. Jeff at High Water Sound is his U.S. distributor who presents his variety of products at those shows and others (i.e., Raven Tables). The Horning Hybrid speakers that I now own, I purchased at the show after it ended. They were demoed with the 300Bs that I would get later. My 300Bs were the 3rd pair made by Thomas. Today, he's still making the model, but the cosmetics have dramatically changed to satisfy the high end market as they sell for $30K. As for my 300Bs, I will find out from Jeff how they were improved beyond their look. I hope so, as the original retail on mine were $18K and I did not pay that. I can say that they do not lack in transparency, and they are the finest piece of equipment currently in my system.
