I was also wondering if anybody else finds 45 RPM albums to be too noisy?
i’d say you have to be more specific about 45rpm albums. and not all turntables are created equal.
i likely own 95-99% of all the 45rpm albums out there (1500+) produced in the last 25 years, as well as most from earlier eras, and they are very quiet as a group. OTOH since the record is traveling at a higher speed, the lead-in grooves and between cuts will have slightly more ’noise’. but the signal to noise ratio of the musical data is better than 33rpm since there is ’more’ data. the noise recedes farther into the background, more detail and nuance emerges, and more music comes out.
but if your turntable is not quiet (more rumble and flutter or actual motor noise) at 45rpm, which some are not, then, of course, that is what you will hear. obviously the better turntables will be quieter at the higher speed.
and........if you are referring to the 70’s and 80’s 12" singles and ’dance’ re-mix 45’s, those are a crap shoot as the quality is all over the board. many are a mess and noisy. they were generally not mastered and pressed with great care. a few though, are very quiet.
