DIY TT

@vinylzone To not detract too far from your entrance into this thread, I believe your  TT with the new adornment of the Maple Sub Plinth has improved on the role over the Plywood it has replaced.

I know this wood is selected for use in musical instruments for its damping properties, and more importantly how it impacts on the overall structure of the musical instrument when present and carefully attached, I would class this as a complex structure.

My structures produced are not complex and I have even produced a structure that can have a Sub Plinth in suspension on O Rings, a little like a SME Suspension Method.

I chose not to follow up on this method as it was precarious and not really trusted with valuable equipment sat upon it.

The Solid Tech 'Feet of Silence' have offered a variant of this type of a suspension support, and have been very satisfactory and remained as the most valued footer.

Their offered improvement over all other used footers, at being able to deliver a noticeable removal of smearing and offering increased perceptions of attack, dynamics, envelope and micro dynamics is quite something. 

Your structure and your use of Maple is not as complex as a musical instrument  structure, but I feel it can impact on the SQ in a manner that makes it a worthwhile choice.

Subjective evaluation from, in use/not in use periods, might give the additional reassurance for the choice made, but I would assume you have already experienced a this when the Plywood was swapped for the Maple. 

Having a few friends over is good thing, I would not deny anybody that experience, if it good for the mind, its definitely good for the body and spirit.

Would the average enthusiast for using LP's to replay a recording, find it  necessary to use such an experience to suggest that a few subjective evaluations, where a friend or two likes the experience and musical encounter with their preferred music being replayed, is an evidence that you are an authority and guru on a set up for a LP replay.

I am not sure he is claiming guru authority?
I thought it was more like a description or observation.

I would probably have stayed with the plywood if I thought it was vibrating, just because I “believe” it damps better.
But the maple should be stiffer, and in a system mounted on a solid wall, it makes sense too.

Anyhow… I appreciate @vinylzone  input and yours.

@vinylzone , I really do not want to be a Pita. I think you did a great job building your own table. My intension was to suggest improvements no get into a battle.

Any vibration coming from the cartridge should be dissipated in the tonearm. Nothing should be getting to the plinth. Unfortunately, you have a unipivot arm which is much poorer at dissipating energy than an arm with fixed bearings. You have loads of noise getting to your cartridge. You could place the table on a MinusK stand but that is expensive. You can isolate the table on your own for much less money, a fun thing to do. 

As for my turntable yes, I had a problem with feedback because of a resonance issue given the prodigious bass my system can produce and the location of the turntable. That resonance has been entirely mitigated with a simple modification. The turntable is now dead silent under any circumstance and nothing phases it including jumping up and down in front of it and charging into the cabinet it rests on. Given it's suspension, magnetic thrust bearing and isolated dust cover it is as quiet as a turntable can get. Speed deviation is no more than +- 2 thousandths of a revolution. At this very moment it is +- 1 thousandth going slowly back and forth between 33.334 and 33.335. As it is also a vacuum table most of the surface irregularities have been sucked out leaving only spindle hole eccentricity as a pitch modifier. With a concentric record pitch is delightfully stable. As good or better than any turntable made. Not bad for 15K. I also get a bunch of kudos for my finger joints. Life is good:-)

Literally woodworking finger joints?
or figurative finger joints like give someone the bird? 😂
