I thought it was called the Limited Edition Pro or is the Pro-250 a different model

Oh, I can't forget to mention the Andre Theriault Black Beauty tonearm. Multiple layers of solid carbon fiber. Mounts on a single bearing. No strings, wires or other supports.

Simply beautiful Caelin

How long did it take Louis to do the install

Hm, about 2-3 hours with Richard's help. Then, we had the opportunity to listen to a lacquer master of Elvis Presley that he had brought along. I wish I had one of those!

Is that stand included as part of the Pro/250 or is that an added option

You can use your own stand or platform. The KRONOS stand is nice because it holds the power supply and it matches the turntable.

I didn't realize that Louis had brought the stand to market

Congrats Caelin.

If it sounds as good as it looks...

Cool! We got ours too, all set up, but still waiting for the cart, an Ortofon A95 that should be arriving soon!

why are the 4 corner posts on yours black plastic and the 4 on Caelin's are polished chrome

They look like black anodized aluminum or SS, not plastic. They would not be plastic holding the suspension rubber rings.

Steve Williams · Mar 29, 2015

Plastic was indeed a poor choice of words . I like the look of the polished chrome on Caelin's unit better than the darker posts

Congratulations Caelin. Quite a lovely looking table and arm and I love the integrated stand. It's a very complete, and well finished looking product. I bet it sounds excellent.

Could you explain how this photo describes setting the azimuth? What is the process? To me it looks more like the lines are used to align the edges of the cartridge for proper Zenith setting. That is, making sure the cantilever matches the tangent line at the null point. A similar alignment guide is printed on the MINT protractor at the two null points, though there one actually aligns the cantilever itself at the null point rather than the edges of the cartridge.

The headshell has mounting holes rather than slots, so how it the overhang adjusted and is there enough play between the mounting screws and holes to rotate the cartridge slightly in the headshell for zenith adjustment?

Also, it seems that at least three recent high performance turntable releases have been belt drive with integrated suspension: TechDas AF1, AF2, Kronos. This is in contrast to the Wave Kinetics and VPI DD tables. I wonder if this means that speed issues with belt drives have been dramatically reduced.

Great packaging with those flight cases. Thanks so much for sharing the photos of the installation. Wonderful looking system.

The template shown was for lateral cartridge alignment but we were doing several adjustments at the same time. I am not an expert although I have had many turntables since the 1970's. Louis did all the setup and I just observed. Actually, the azimuth adjustment is unique since there are no wires and anything else attached to the arm. I should take a closeup photo so you can see how the arms is "mounted". It just has a ball attached to the bottom of the arm and that ball sits in a cup that has a lubricant in it. The counter balance weight can be rotated around the polar axis of the arm which causes the azimuth to change. But the arm just floats in the ball cup - no other attachments. I had a Well Tempered table and arm that was pretty elegant but this is even simpler.

The Kronos uses DC motors that are digitally controlled for speed. Each counter-rotating platter has an independent motor and is controlled independently.

This is my final turntable and am very happy with its performance.

Very cool and congratulations ! Curious how a log cabin room sounds? I suspect the walls really help with difraction

Maggie's are great speakers...hard to beat for the $$'s
