Bin dug noisy records. Does it diminish your enjoyment?

Depends... 

If is a quiet solo piano piece of music, then I'll likely pass. There is nowhere for the noise to get buried and it can become too distracting.

This is usually where I get my "guilty pleasure" recordings. Sometimes I get very lucky, other times not so much. It's also where I will try something different.

If it's a record I'm really pining for, I will seek out a "proper" copy.

Learned early on with this latest return to vinyl (six years now) that an RCM is a must have. Started using home brew, a painting pad, microfibre cloth and a dish drying rack. Tried the Spin Clean to no avail and gave up on it. Best accessory I ever got was my Okki Nokki. Three wash cycles followed by three rinse cycles using L'Art du Son. Overkill I suspect, but at least I know they are as clean as I can get them with the tools I have.

If a record looks dirty, doesn't matter. I think of it as a protective coating :)  Light scratches don't really matter pending the profile of the stylus.

Going through the bins is a relaxing and meditative process provided you leave enough time for it :)

certainly more fun than file or cd.

It's a hobby within a hobby 

When I first got back into vinyl I was doing a lot of thrift store picking. I paid $1 for the majority of my collection(that wasn't inherited.) I eventually built my own ultrasonic cleaner that is similar to the one in the above link. It cleans 3 at a time. I then rinse in distilled water, vacuum them and then I have a piece of lab equipment that removes static. The process is a pain. I have found that the Spin Clean actually does a fantastic job for records that aren't in bad shape. I start there now and if it needs more, I go to the ultrasonic. My digital front end sounds so good these days that I find myself listening to vinyl less and less.

I don’t collect noisy LPs. 

I have a few. I don’t listen to them. 

Sometimes some LPs that I buy develop pops right away, even though they go straight back into their inner archival sleeve after playing. I’ve never understood why that is so.
