Well listened to both this morning. Moanin' sounded pretty dang good. Dynamic range was present and felt there was good separation of instruments. I did have an occasional crackle or pop, but I haven't run it through my VPI cleaner yet. Also, the noise floor was a bit louder than the MM SRX version, but that was expected.
Soul Station was crisp, clear, and dead silent. I'll probably reach for this 33 over the 45rpm MM more often than not just for the convenience factor. No complaints on this one at all.
It would appear Optimal has some quality control issues based on what others are reporting vs. my experience. Hoping everyone can get their hands on a good clean copy.
