I was recently fortunate enough to purchase a pair of 626R's with a few years on them...but almost fully upgraded (FST, TRT, Soundcoat, Megawoofers). I'm running a strictly 2-channel setup for now and keeping my options open to a sub or center in the future...living in an apartment now so the sub would definitely have to wait.
The thing is, I would really love to be able to keep these speakers for a very long time and could easily see myself doing it. However, the Bud Baily cherry cabinets (and that huge VMPS sticker on the back!) are causing me to ogle offerings from Salk Sound. Even though I know it is all about the sound quality, I have a feeling that an MLS cabinet upgrade might help stave off any upgrade-itis. But at $400 for cabinets, plus $300 for soundcoat and black hole 5 / SR-71, it is quite an investment. Also, there are the new 40 oz megawoofers for $180.
I would love to do it, but really feel like I need to know it will give a significant sound improvement as well. Can anyone comment on the difference in sound quality in the cabinet upgrade? Ditto for soundcoat, black hole / sr-71, and the newer megawoofers. I could definitely use deeper bass since I am not running a sub...but how noticeable would it be (if at all)?
Just for reference, I am running these through a Rotel RSX-1056 receiver, which is rated at 100 watts in 2-channel (and uses a Burr-Brown DAC). Would this cabinet upgrade money produce a greater difference if it went into an amp or pre-pro? I fall mostly into the camp of believing the source quality (music source), speakers, and room make the biggest difference...but I am willing to listen to everyone's ideas.
Thanks.
Edit: Also, can anyone link me to pictures of the MLS walnut cabinets...Brian says those and rosewood are all that is available right now. I've seen plenty of the rosewood but none of the walnut. Thanks.
