"The job of a turntable is to spin at the proper speed, prevent any spurious vibration from getting to the tonearm and sound like NOTHING. Anything it adds to "the sound" is distortion.
The job of the tonearm is to hold the cartridge solidly in the proper orientation, move to two directions only and absorb any energy coming from the cartridge to prevent it from reflecting. It should also not have a "sound."
The job of the cartridge is to translate the physical waveform on the record into an electrical waveform. It also should not have a "sound."
It is the record that "sounds." A record playing machine should not add or subtract anything to the sound that is on the record. The design of turntables, tonearms and cartridges should be evaluated with this in mind.
A record player is a vibration measuring device. The cartridge has no way of knowing where the vibration is coming from. It will turn any vibration into an electrical signal.
The environment is loaded with vibrational energy and the turntable has to isolate the other parts of the system from all of it.
Mass will not do it.
If a turntable does not have a proper isolation suspension then it should be placed on one.
It is much cheaper if one is built into the turntable.
The Dohmann Helix is probably the epitome of a suspended turntable. The classic is the AR XA followed by the Thorens TD 125 and the Linn LP12.
SOTA was the first to hang a turntable from springs instead of sitting it on top of springs, a much more stable design. Basis, SME and Avid followed suit.
The RP 10 is a lot of turntable for the money. It is suspended on squishy rubber feet. It has a very stiff chassis and a great tonearm.
Up from that price wise is the Sota Sapphire with a Kuzma 4 Point 9 then up the Sota line to the Cosmos.
At this point we are already above the OP's budget but continuing onwards are the Avid Acutus and the SMEs. Next is Basis then the Dohmann Helix. Both Sota and Basis tables can be had with vacuum clamping.
When a tonearm tracks over warps the groove velocity changes and causes pitch to waver which is painfully obvious and far exceeds the minimal wow and flutter most modern turntables have. Vacuum clamping is the best at flattening the record. Reflex clamping Like the SMEs, the Acutus, non vacuum Sotas and the Helix is second best.
A record weight does little to nothing. Ring clamps are a PITA to use and an accident waiting to happen.
Of the turntables I mentioned above only the Sotas use a magnetic thrust bearing which is an advantage in terms of noise and durability. It does exactly the same thing as Techdas's air bearing at a fraction of the complexity and cost."
Bravo!
What an informative post that was.
It's a pity that posts like yours above can't be pinned for future reference.
