300 rpm motor for VPI

Your new motor has nothing to do with what you are hearing, brf is right. Check your wiring, arm, cartridge alignment etc. as something got knocked out of whack. BTW, I have an HW-19 with a 600 rpm motor and a Prime with a 300 rpm motor and they both sound just fine to me. Don't let people discourage you about your new motor, it'll be just fine.

tzh21y, four years or so ago you posted a thread about your experience with going to the 300rpm motor and expressed dissatisfaction with the 300rpm motor due to increased noise; you decided to go back to the 600rpm motor. Is this the same unit that you are trying again?

I think that what you are hearing could, in fact, be do to the motor; especially if it is the same unit which may have issues. I think that the key may be your subwoofer. Question: where is your sub located relative to the main speakers? Contrary to popular opinion only the very lowest bass frequencies are, in fact, (mostly) non-directional. It is quite possible that if you have your sub positioned to the right of the soundstage that any low frequency noise, even if very subtle, that is being generated by the motor could skew the perceived balance in that direction. Did you try disconnecting the tt belt and turning on the motor with the stylus on a record to see which of the two motors is noisier?

Actually, I am back to the 600rpm.  the 300 is just does not sound right on the scout.  the 300, although sounds bigger, does not portray the music the way I like it.  The 300 gives a larger soundstage at the expense of just not sounding right.

you really need to look at the alignment on everything.  Eyeball the back of the tonearm at eye level and see if it looks level or if a side is lower than the other.  Look at the needle as you play a record at eye level to see if its perfectly perpendicular to the record.

tzh21y-I've been following this thread. So did going back to the 600RPM motor eliminate the problem? I personally questioned it being suspect, but audio problems can sometimes be logic defying.
