As the stylus makes its way to the center of the record there is less and less length of a groove for every second of time. The same is true for 45 RPM records but the added groove length per one second of playback is longer in length. This means a signal can be recorded with wider dynamic range and the increase in inner groove distortion is less on 45 RPM records than 33 RPM records.

Dan, always a great reply. I always assumed, for some odd reason, that 33 was better and for full albums whereas 45 were for single track.
Your explanation is very clear and makes a lot of sense. So the best sound would be 78 but then you'd be limited by the total length of play (10min per side at best) which would be too inconvenient and too costly.
