Hello! This is my first post here.

I'm hoping someone here can explain some issues I have as I take on the task of recording my vinyl record collection onto CDs. My first issue is the poor sound quality of a small few of my records. I'm not talking about the usual wear and tear crackle issues, but rather issues that were present when first played when I bought them. I have about 500 45s that I collected back in the mid 70s to 1980, and about 200 LPs

Some of these records produce a raspy crackly sound when the sound breaches a certain level. This is short MP3 cut from a Barry Manilow tune that demonstrates this issue:

This record has been played a few times, but I'm certain this effect was present from the get-go. My standards were pretty low back in the 70s.

I'm recording both sides of my 45s. I've come across some B-sides which I have never played with the same issue. Here is a really bad one I came across last week. It is a short B-side MP3 excerpt of a Janis Ian single that never, ever had been played previously:

This is a 7 minute song on a 45, so that may have something to do with it. I suspect these problems are manufacturing defects. I'd just like someone to confirm this....or maybe a turntable cartridge replacement might resolve this? Anyone dealt with this issue?

Now to cracks, yesterday I recorded a B-side of a Bad Company 45. This is at the beginning, and again, this side had never been played before:

This drove me nuts! How can a never before played record sound so worn?

Most of the records are recording very well. I'm using a Pioneer PL-670 direct drive turntable with its original cartridge, routing it through a Pioneer receiver, and out to my PC through an SB Audugy input. I use GoldWave to record and edit the WAV file, and I use Groove Mechanic to clean the pops and clicks (it does a pretty good job too! - but it can't fix that Bad Company dissaster). All my records have been well maintained, all in their original sleeves, and stored at room temperature in the upright position

Thanks,
Buddy
