Speed Box S speed question

Hi,

Running a Pro-ject 5.1SE through the Speed Box S. Why do I have to play my LP's at 45 (rather than at 33) in order to get accurate playback? The 33 setting is much too slow, while the 45 is on key and pitch.

Still not sure if the SB makes any noticeable difference, and since I don't plan on spinning 45's, i might just return it and invest in a better cartridge.

Is this where you have it? Speed Box S Manual

Hmm. Don't know if I'm comfortable with this.
