Phoenix/Roadrunner will help speed accuracy and stability, but how would it do anything at all to cure off-center LPs of their off-centeredness?
LP's: the measure of off-centre record spindle holes ?
Good day. On the basis some are more sensitive to pitch than others, the measure of how far off centre spindle holes can be before they affect enjoyment of music will of course vary. I'd be curious if there is something like consensus on this dimension from the seasoned LP lovers on the forum ?

Well I said hopefully. When an off-center lp rotates, as the cartridge sees it in real time there’s a slight speed offset, IMO. Therefore any cause of speed irregularity could possibly be corrected by a device such as the Eagle/Roadrunner that constantly monitors speed at every rotation. Maybe a better way to say it is any deflection (tracing error) regarding the cartridge/arm’s ability to trace the lp perfectly will cause some speed irregularity. This is of coarse after I've reamed out off-center records to the best of my ability as stated above. |

That’s because the LP with off-center hole can’t affect platter speed, but only the effective speed of the phono cartridge as it tracks the eccentric disc. |
