Yes, lovely, isn't it?

Unfortunately, they are sold out on the model from pre-production orders, and they may be available again in January. However, I'm sure they will take advance orders on the model, for the next production run.

That 340 will likely give any TT made a tight run for the money. Probably beat most quite easily. And a steal at the price.
David, the platter is constructed using the W.E.S.T system of epoxy resin soaking the wood, like is used in modern wood boat construction. The platter is pieced together like a puzzle, with the grains of the pieces oriented for maximum strength and minimum movement. Then it is machined after it is cured.

The stability of the platter was a big concern for Chris when he started this project. He feels it will be fine. It is a very labor intensive process, and this contributes to the higher cost of this table.

It is reported to sound awesome. I haven't heard this model.
Jyprez, after using many TTs with MDF or acrylic bases, I might agree that they may be stable, but they don't sound anywhere near as good. This was really shown to me in a big way, when I upgraded my Teres from the acrylic base to the lead-shot loaded Cocobolo base. Everything else in the TT remained the same: same bearing, platter, feet, arm, motor. All I did was replace the base on my existing Teres 135 with the base of the 245 model. Even the thickness and shape was the same as the previous acrylic base. The difference was too much to believe. Simply the material choices created such a staggering improvement, that I understood forever how much these materials play a role in the sound. I'll never go back to an acrylic TT.
Please, with all due respect, this is not a boat. In normal temperature and humidity environments that would be encountered in a high end audio home, this is not a problem.

Look, electronic circuits don't last long in salt water immersion tests either. I think we have to be at least semi-realistic about what we are discussing here.

Great care went into the design and manufacture of this turntable. Long term stability was one of the concerns, and it was dealt with in the best way possible. Given a normal environment, this will be quite stable.

I certainly wouldn't recommend this turntable for outdoor patio use in the tropical rain forests of Brazil. For temperature and humidity controlled indoor living room use, this will do just fine.
Nope. Never had anything to do with Teres. Only own their turntable. And love it.

I use the Teres Cocobolo base. It is not sealed, other than a surface finish. Last time I looked, it was still on my shelf. Hadn't crawled off anywhere. I live in an area with over 90% humidity for much of the year. Smoky Mountain area. I have no air conditioning. I use a wood stove for heat. My TT is right near the glass door and is subjected to near freezing temps in the winter(when the stove goes out during the night), and over 90 degree temps in summer. Finish is still on, and stability is fine. It is not made nearly as stiff as the platter on the 340. I don't know what extremes you feel any TT is going to be subjected to, but I'm certainly right up near the max in that department.

I also work with wood. I make musical instruments, specifically acoustic guitars. I am keenly aware of wood stability characteristics too. I believe that a nearly 4" thick platter of puzzle-fitted hardwoods with a density so high that it will nearly sink in water, and then soaked in an epoxy treatment that is made to withstand permanent immersion in water, will do just fine in the home environment.

Now that you've questioned my motives, maybe I should question yours?

And let's look at the stability issue and its real implications. Let's say that it might even go out a few thou periodically under extreme conditions. What are the potential problems?
1) Let's say it goes out of round by a couple thou. Well the TT has a continuously monitored platter speed that is constantly being read by an optical sensor and feeding a microcontroller that maintains speed to less than a tenth of a percent continuously. Controller takes care of that. And yes, it reads the platter, not the motor.
2) Let's say it goes out of shape like a potato chip by a couple thou. Well, most records are at least a couple thou out anyway. The system handles those quite easily. No problem.
3) Let's say that it squeezes tighter on the bearing shaft. No problem, the bearing shaft is part of the spindle, and is not immersed in the bearing well at the section where the
platter is attached to the spindle. Can't affect anything there.

This is worst case. Please don't tell me that you think it is going to go out by inches.

And how about the many turntables which have MDF platters and bases? They don't change with temp and humidity conditions? How about aluminum? Doesn't it change with temp? How about steel? How about brass? They don't change? Of course they do. Do they change evenly? Maybe. Maybe not. Depends on if there were any stress risers in the material when it was made. That's why they cryo treat rifle barrels.

Yes, I think it is good that you make people aware of the characteristics of wood. As you say, buyer beware.
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.
