why sound is so different?

When I got into vinyl about 4 or 5 months ago, I was disappointed at first as well.

Part of it was the choices of vinyl; vinyl varies greatly. From both listening to my old collection and buying re-issues etc, some sound like crap and others sound incredible. Another aspect was the cartridge I was using - it sounded dull and lifeless. I'm now on my third cartridge and my last two sounded bright before breaking in (but they're not dark now either).

I received advice telling me to 'hang in there', that it would pay off with some amount of work and it was correct - so hang in there!

Jorsan, I'm using a Dynavector 20XL cartridge.

Again, keep in mind that even with perfect setup, great equipment, some vinyl just sounds like crap. An example:

One of my first LP purchases 4 months ago was Steve Miller Fly Like an Eagle. It was $9.99 and heavy vinyl and I was excited to put it on and hear no surface noise (which was my biggest fear getting back into vinyl). It sounded crappy and when I compared to my CD (which sounded good) I was convinced something was wrong with my setup. Then over time I read more than once that particular LP was a crap resissue. I bought a MFSL reissue on eBay. Got a great copy - no noise or scratches and it sounded better. Today for kicks I pulled out my version from the 70s which earlier I wouldn't even have contemplated playing (I didn't take care of my LPs back then) since it looked in bad shape. Yes, I hear surface noise but otherwise the sound is spot on correct. With the two other versions the bass is raised, vocals recessed and sounds lifeless. This version sounds great.

I made the mistake of thinking that a 'good' pressing was simply a quiet one. I also thought MFSL were the bees knees. I was so wrong. Count me now in the category of preferring a proper/analog sounding mastering with surface noise than a quiet dull or bassy one.

If only I knew this before spending so much money on reissues and expensive MFSL on ebay.

Hope this helps.
