Just a thought. What kind of cleaning gear you have to clean your records? I believe it plays a big role in vinyl sound.
I used to have a Michell Gyro SE MKII and just recently sold it to upgrade to a Teres 255. The Michell I have never sound like what you are describing on my 50's and 60's recorded vinyls. It has to be others like cleaning, cartridge alignment, phono pre, amp and preamp. I also use an OL Silver so to that, I have no doubts. Also, 50 hours on the OL Silver is nothing. Maybe given more time, it will show its true colors.
Dry, Zippy, and buzzy? Maybe the VTA is to high?
my 2 cents....
