Christian.....I use the series 5 and 6....I like the 6 better as they use larger materials through out but the series 5 is nice for what it is. I have no issiues with the MDF, they sit atop aluminum cones that fit firmly into the cross members of the rack which couples the MDF to the frames so vibrations can move away from the shelf. In my current listening room I have suspended floors and when I had the Adona racks which weigh twice as much as the Solid Steel I got the same foot fall movement......maybe a bit more with the Adona as it was a heavier rack The Solid Steel is very rigid, built well, accomedates tall amps and price fair.

Christian- it will be far easier to isolate your turntable from a springy floor by using a wall mount for your turntable, unless it is so 'massy' that a sheetrock wall won't support it.
I guess I've had a fair amount of experience with different racks and isolation devices over the years, from the early days of Target stands and turntable racks, to a massive, custom built Billy Bags unit in the later 90's, to the big dog finite elemente unit, to Grand Prix using the carbon fiber shelves and apex footers (which I still use for the line stage, its power supply and for amp stands); I also use an HRS platform directly beneath my turntable, which in turn sits on a very heavy, large antique prayer table that must weigh 300 lbs. That, with some judicious use of sorbothane under the prayer table legs, fully isolates my table, which has no suspension, but you are talking about a considerable amount of weight- the TT alone is around 160 lbs, the HRS platform must be another 50 or so and the prayer table is double all of that. I think part of it depends on what the foundation is that the rack sits on, part of it is exactly what you are trying to achieve with the rack (you could conceivably use the rack as a solid foundation and then add aftermarket decoupling devices) and obviously, there's budget. There's also alot of different theories and some science on coupling vs. decoupling, which I'm not going to pretend expertise in, but there are basic questions about what you are trying to achieve, ie, isolating from footfalls, like a turntable problem is a different issue than trying to deal with component vibration generated by the component itself, e.g. a tube preamp or CD player. There are also issues of damping, by placing weights on top of various components. One trend I've seen is to get away from elaborate stands that perform the isolation or decoupling, use a simpler stand, like the Adona, and have the flexibility to 'tune' the components (not so much turntable but electronics), by using various aftermarket coupling or decoupling devices. I just had Adona make a small 'amp platform' for the tube power supply to my phono stage. It is very well made, uses their skinny cones to couple with the floor (really more like a spike) and was quite reasonable in price. I am now experimenting with various aftermarket decouplers between the platform top and component, essentially to tune the sound. Last edited by Whart; 07-25-2012 at 08:44 AM. |

You can also fill SolidSteel racks with leadshot or sand. I still have the Solidsteel racks but they are currently not being used. Last edited by MyPal; 07-25-2012 at 09:11 AM. |

Wow, I actually almost went for the newer Salamander Synergy series. Glad to hear first-hand experience about them.
I read that concrete blocks store and release low frequency vibrations. I guess that's not so good for a turntable if that's true. The suspended Michell sounds okay though on the concrete block / pine combination.

I've read elsewhere that some people put their own shelves on the Solidsteel racks in place of the mdf, either wood or heavier mass shelves more like the Adona. While it's nice to have the option I guess, I don't know if it would result in the rack being any less susceptible to vibration. Quote:
A wall rack is not really an option right now... The wall that my turntable is on is adjacent to another condo unit and whenever my neighbor shuts doors, the wall kind of vibrates, I think.

Right. Wasn't the old way to mount a Linn to put it on a very light table for that reason?
