Interesting it only took about 20+ years.
I have had these for about 16 years or so. It may sound strange, but even with a dedicated room having good dimensions, it has only been in the last several months where I feel I have really finally gotten them dialed in. Each time in the past when I have felt this way, I will make a change in something, often as small as a few inches here or there to great effect. As you have mentioned, we know so much more these days about acoustics and associated gear, that these speakers have been anything but static in their performance. They have just continued to grow over time. I often wonder about folks that keep speakers for much shorter periods of time, if they really ever have the chance to know what they could really do?
There have been other speaker systems that have tempted me over the years, such as the also now discontinued Genesis IIs. Designed by the same individual, I saw them as nearly a direct replacement. But would they have been that much better? Then, there was the cost, wow. It was the cost factor that has kept me out of the market for so long. I believe the last run of RS1bs did sell around 7K. Mine are more the middle of the line and were probably closer to 5.5K (I am the second owner). Also as you had mentioned, a lot of money for back then.
What I have grown used to is a system that sounds small with smaller scale works, yet also huge when called for. I love that wall to wall presentation with monolithic sized speakers that just disappear into the room seamlessly. That says a lot when the front wall is 21.5 feet wide (I have them set-up on the long wall).
That brings us to VMPS. I have been following that line for years ever since I owned some of their original subs for my Acoustat 1+1s. I have felt for a while that the VMPS line with their marriage of ribbons and cone bass drivers might be ideal for me, but would I miss the dipole nature of what I now have? I also own some CLS1s that I occasionally switch into the mix in my room, and I have grown to appreciate what these dipoles, both stats and ribbons, can do.
Now with these RM V60s, I have the choice of maintaining a full dipole effect, or tuning that down to what my room would like. That is very unique indeed. Their entire concept and entry cost being such a new product make them a very interesting proposition. They are certainly not free, but far less than other so called 'state of the art' systems.
I guess I will see what happens here. I plan on posting on Audiogon a bit later. Hopefully someone will be taking these off my hands and getting a very good deal, while I will be moving towards the RM V60 and also getting quite a bargain in the long run, for the long run. I have the impression that these too are speakers that will have a performance envelope that will grow and expand over time.
I wish I could keep everything, but I just don't have the room to store things. Besides, these Infinities really deserve to be in use.
