Where you measured 126 dB just on the bass units, do you think playing records in that environment might’ve helped you get to that 126 dB via mechanical feedback loop sound to phono cartridge even if it didn’t break out into full out howling or motor boating?
No, the test was made with a CD. We then tried records, and got as loud. With some tweaking, of course.
There are frequencies you need to be aware of in using the SL-1200 record player; first you need to lose everything below 30Hz-ish, then you take a few dB at 100Hz and then you're mostly set. Providing you're mechanically sound in your set up, see below.
There is a tonearm resonance at 400Hz but to get there, you have to be really far out. That one can be triggered even if you're really well isolated mechanically; because it gets through simply on air pressure variations. I've never had the problem in the wild, but I've provoked it in the shop just to get a feel for it.
Most of the bass resonances OTOH come in through the feet, so you fight them with a setup of the sturdiest table you can find, then four fist sized pieces of soft yet sturdy "flightcase foam" placed in a rectangle like the feet of the record player; on top of that a 30mm steel plate the size of the record player, then the record player on top of that. Nothing may touch the record player except the feet, and the cables must be looped loosely.
The realities of playing mechanically stored music at insane levels with intoxicated people around do prepare you for accurate judgement of the misconceptions of the more scientific-word-using audio-phools, because their claims of "dramatic influence on music" are made at levels 40dB lower than what you usually get people to dance at -- which means two things;
- People dance more if it sounds good, so you did good. By definition.
- The phools play at levels that are ~ 1% of what you do, and consequently they have a much easier problem. You're a 100 times better at what you do than they are.
Brag-ingly,
