Wet wood? Are you familiar with the moisture content of the wood before it goes through the process that Teres uses? I know I'm not. I understand from reading the Teres web pages that there is some extensive cabinet making experience at their disposal. I doubt they are going into this blind, and I really doubt they would go to the expense and trouble of this process as just a marketing tool. Some exotic, space-age man-made material would fit that bill and without the headaches of possible future problems. As a part-time woodworker you should appreciate that the exotic woods that are being used here are not your average cherry, or oak, or maple, or mahogany, etc., that are used in furniture making. Teres has stipulated that movement is concern, but I agree with Teres that the movement in question here is much less than what we see with furniture.

Anyway, I would still love to hear the 365 or even the 235. But I fear that if I do I will never feel the same about my current TT.
Actually MDF will not change with temp and humidity. I once soaked a piece of MDF in water for days and could not measure the change with a micrometer. I can't speak for acrylic as I am not sufficiently familiar with the characteristics but perhaps a materials engineer out there can answer this.
You ask how many turntables have MDF bases. I would say a great many starting with the rega. How about speakers as well. Most all are made with MDF and a wood veneer. How many solid hardwood speakers do you know of?

As far as subtle changes in the wood. I am sure that teres has accounted for the most significant changes in their design. I certainly would not expect movement observable to the unaided eye or I would quickly ship my table back. But as you yourself have pointed out to all of us many times in this forum, turntables are exquisitly sensitive devices where tremendous differences in sound quality can be achieved with very subtle changes.
So let's see, should I play my records on a base with random and uneven density that is subject to even subtle expansion and contraction? For my part, I think not. But the ear is king so if it sounds better to you, then I say go for it!
To each his own. I have no interest in making an argument over this. I don't even have the blasted table. And it is likely that I never will, because I can't afford it anyway.

They made the table that way because they thought it sounded better and felt they could make it stable. Time will tell.
One final response to Dan ed ....
I say wet wood because all wood is wet at some level. The cell structure of wood makes it like a sponge, even when kiln dried, the moisture content is only reduced, never eliminated and will still change to be in equilibrium with the surrounding air.
No TWL does not work for Teres but I clearly appreciate his support. Thanks Tom!

About PEG. PEG only works with wet or green woods and it is not effective with the dense woods we use. Yes kiln dried wood still has some moisture, but not enough to work with PEG.

I can't believe that you are seious about soaking MDF and it didn't change dimensions. MDF has terrible dimensional stability. It swells like a sponge when it gets wet. The advantage of MDF is that is does not warp. I have done a number of projects using painted MDF and you can always see the joints after a short time. It's no worse than solid wood but it certainly is no better. I have tried MDF for a turntable base and it's not bad, but nothing like hardwood.
