Which turntables?

STANWAL, to state that " I don't think Yamaha made them so it is an OEM one or a renamed model from another company." you have to be pretty sure . this is simple not true. I really think you are very knowledgeable in audio field, and you can list all people you know, but if you are not sure, do not post misleading advises. Yamaha, which i currently own, along with sony 8000 i also own, is a very decent table and by no means OEM. Denon 59L, i used to own, could not produce decent sound, being hooked up to VAC PHI-2 trough VAC PHI-70, trough stealth audio indra cables, and meadowlark IBIS speakers. I write from my own experience, not from words of others.

Gtm...my Mac stack is bigger than your Vac stack...

Mac Vac whatever

I have no horse in this race as I have never owned any of the three you have listed here, BUT! I truly do suggest that you keep all three and try to use each or maybe rotate each through your system(s) as each are beautiful classics and can hold their own against almost any turntable one can find today short of those more esoteric and uber priced ones sold today. If I had the three you note here I could not make my mind up to get rid of any unless one or more are no longer operating properly. If you do decide to lessen the number down by all means list one or ore for sale as you will have no problem selling any of them.

Personally, I am not sure it matters whether Yamaha manufactured it or not. If Yamaha designed it and had the good sense to have Micro Seiki manufacture it, more power to them. When I am back where it is, I can check to see if it says anything on the back about MS manufacture. In any case, the PX-1 sounds great.
