rumble issues - see old thread update

Nope, no dogma here. I specifically included this is my opinion.

The granite was added on top of the craz, if I read Tom's post correctly. If that extra mass reduced oscillations getting to the speakers, something is moving too much. I didn't mean to point directly at the Craz, just whatever the table is sited on. But if that is the Craz, well not everything works in every application.

The Stillpoints are the limit I will go with compliance under my Gavia, and even then I know it is a compromise to the sound I could get with a braced, aluminum shelf on my sandbox. If I ever grow tired of that beautiful Dakota Mahogany granite it will be gone along with the Stillpoints. Remember, I'm coupled to a concrete sub-floor so I don't have the issues of a suspended floor. If I did I might own something other than what I now own. Suspend away if you want or need to. I don't find it necessary or desirable under my table to get a low enough noise floor.

Yes, there are things I hear in the mid and upper ranges differently in your system and mine. But down low is a different issue, and that's what where talking about here. I dont hear any down low in your system, I never have. I have to extrapolate what I think it would sound like. But I realize you do have your system tuned for a different sound than I based on our different preferences. Even as close as our systems are, they are still as different as the music we each prefer.

Agree about the Stillpoints, we both heard similar advantages/disadvantages. Like you, I'd rather not have that compliance so close to the TT. I'd ditch them too if our Salamander rack weren't so ringy (it's like your Dakota Mahogany granite, except for the good looking part!).

That's different from the sort of suspension I was referring to though. We both know people with sub-20Hz systems, very high mass tables (200+ lbs.) and concrete floors. Every one who replaced a big, high mass stand with a Minus K reported significant benefits with no loss at the bottom end. We're not talking bouncy, bouncy Linn here.

Agree there's little down low in our system vs. yours. Our speakers roll off below ~42 Hz. They can't reproduce the bottom octave no matter what we do at the source.

FWIW, our missing low end is not by choice and has little do with sonic or musical preferences. It's a function of geography and budget: we lack room for a sub and funds for full range speakers that would fit.

I'd love to try big Coincidents, which claim 20Hz without being much larger than our B&Ws. They're also easier to drive, have great crossovers and drivers (on paper anyway) and they're not ported - no woofer pumping!

That's my segue back to the topic. Sorry to Tom for threadjacking!

I just finished reading up on that device. Oh, yeah. That MinusK is a completely different league. It had better be for that price. Then again, when you look at the price of decent equipment racks it doesn't look as expensive.

Dan,

If you think the Minus K is pricey (and you're correct, it's not given the price of something like an HRS rack, a Grand Prix Monaco or many lesser performing aluminum, polymer and glass monstrosities) take a look at the Halcyonics device. We're talking serious vibration control for electron microscopy and other critical scientific applications. Both devices make a Vibraplane look like a toy.

HI Richard,

Yes, I never liked the idea of air and pumps.

I did have some time this morning to scan the Halcyonics. The only issue I have with it is that it is active, however it is reported to have a faster damping time. Yes, this kind of device does put things in another league.

I also like that workstation table on the MinusK website. Change out the adjustable feet with spikes. A Billy Bags short table would also work great under one of these, so it would seem.

Employing a MinusK would probably allow me to play through the next quake in the good ol' granite state. :-)
