Another thing I would like to add to my SOTA experience is the mk4 upgrade. A $900 cost with no clear results or clear definition of what that upgrade entailed. Only here say on this site. The receipt I got was a simple line item:
Cosmos Series IV Upgrade
Bam, $900 gone, and I couldn't hear any audible change. I've been told (on this site) that the mk4 upgrade consists of a motor mount change/upgrade. Wow, for $900, there must have been quite a bit of engineering that went into that motor mount.
Once again, A Fool And His Money.
Now that I've done some modifications on the Technics, I can definitely understand how critical it is to keep vibrations away from the turntable. As far as the stock Technics is concerned, it is very noisy due to the transformer that is used (and mounted) in the turntable. Adding the KAB external power supply changes the Technics to an entirely different table all together.
Consider this, that KAB power supply is a $250 upgrade. I think more engineering effort goes into designing a power supply than a motor mount. The SOTA mk4 upgrade is a $900 upgrade. Once again, I have to ask exactly where did that money go to justify that amount? Makes no sense, unless you concede that you are in the 'high end turntable' market and have a lot of money to spend.
I think there most certainly are expensive turntables out there that do justify their cost (I have yet to actually hear one) but consider the history of records. This is an area that is not new and has seen many decades of improvements and change. There is nothing revolutionary since the 70s for turntable technology. Only new materials, and manufacturing techniques.
Where do these new 'high end turntables' justify their prices? I guess you could think of the 'high end turntable' market as an art, that would explain why you should leave your objectivity and cost consciousness at the door.
