Relating to fine tuning the load by weight, you may want to consider using a suitably sized and shaped container appropriately filled with sand or crushed rock.
Springs under turntable
I picked up a set of springs for $35 on Amazon. I intended to use them under a preamp but one thing led to another and I tried them under the turntable. Now, this is no mean feat. It’s a Garrard 401 in a 60pound 50mm slate plinth. The spring device is interesting. It’s sold under the Nobsound brand and is made up of two 45mm wide solid billets of aluminum endcaps with recesses to fit up to seven small springs. It’s very well made. You can add or remove springs depending on the weight distribution. I had to do this with a level and it only took a few minutes. They look good. I did not fit them for floor isolation as I have concrete. I played a few tracks before fitting, and played the same tracks after fitting. Improvement in bass definition, speed, air, inner detail, more space around instruments, nicer timbre and color. Pleasant surprise for little money.

I won't be mounting my Transmission Line woofer cabinets on springs any time soon or ever, thanks. I do go along with getting any speaker up off the floor by at least a few inches if it's a tall full-range type (to de-couple from the floor, you don't necessarily need a springy or spongy support) or by the typical stand if it's a 2-way monitor, but none of that applies to either of my two systems, since both are large planar types, one ESL and one Beveridge which is not quite a typical ESL. |
My nobsound spring isolation feet arrived Sunday, late afternoon. I got them, hoping to alleviate some subwoofer influence on my turntable. I'd noticed some subtle muddyness in louder bass passages with vinyl that I did not detect when streaming the same tracks. After reading several reviews and discussions, I assembled the feet with only 3 of the possible 7 springs in each foot to accommodate the 20lb weight of my Technics TT. For starters, I chose Boz Scaggs' album "Dig" which has several bass-heavy tracks including: "Payday", "Miss Riddle", "I Just Go" and "Thanks to You". The tracks still had good dynamic range, but the low end was less muddy or boomy...revealing better detail. Classical music was better too.... STRAVINSKY: THE FIREBIRD SUITE (1919 VERSION)ATLANTA SYMPHONY ORCHESTRA AND CHORUSROBERT SHAW, CONDUCTOR has passages where the bass and kettle drums come on strong. The accompanying woodwinds and echoes of the hall are more noticeable now. Don't have any "cons" to report as of yet...still listening for any issues. I copied the album info, so forgive the all caps! By the way, this Telarc version of the Firebird Suite is outstanding. Some of the best orchestral reproduction I've heard. At times, startling realism. |
