Save a vinyl newbie, please

I've been stocking up on LP's for the past month and a half, and I finally got a turntable yesterday (a new Music Hall MMF-5). When I picked it up, the guy had it playing and it sounded great! He showed me how to set the tracking force, vertical tracking angle, the cartridge angle (or something like that), and the anti-skating force. He also gave me some suggestions of how to clean the records and the stylus before use. OK, perfect.

I brought it home and tried some of my records on it. It sounded horrible! I get loud pops every second or two. The pops drown out the music. The music sounds muffled, and sometimes it sounds like the ocean from the tweeters (particularly in the right channel). The situation only gets worse with the volume turned up.

I tried it with several of my best-looking LP's last night and still couldn't find one that was even listenable. I have a couple sealed records, so this morning I tried them with the same results. I called the place where I bought it and he said that only about 10% of records that I'll find actually sound good. That sounds like a good incentive to go back to CD's.

I'm using the MMF-5 with a Musical Fidelity A3cr preamp, Audio Valve ppp45 amps, and Audio Physic Tempo speakers. (You can click on my system for more details.)

Please let me know if you have any suggestions!

Until you get it right, lay off playing your best lps. No use having to replace them due to permanent damage.

Something is terribly wrong. Most records, used or otherwise sound fine. First thing is to do some tests. Reverse the leads on the phono input at the back of the MF. You said that the right channel was worse, if the left channel is now worse it is a table setup matter, if the right channel is still worse, your phono preamp has a problem. Check to make sure that the ground wire is solidly attached to the grounding screw. If it is the table, and you have verified correct tracking force, anti-skate and overhang then the next thing to do is screw with arm height. Lower the arm a very small amount at the pivot point and report your results. Finally, you might consider posting what city you live in and one of the sorry asses that spends too much time on this forum might be glad to help. Hell, if you live in Portland, OR I'll be over this evening. You buy the beer; I'll bring the records.

If the exact same turntable sounded great at the dealers then the problem is not with the records, it's got to be some sort of setup issue. Unless you changed any of the anti-skate, tracking force, etc. since he had it playing you can rule those out too. Look for things that changed when you moved the table.

1) you might be using a preamp with a different mm/mc loading than the one at the dealers - see if it's adjustable to a more precise degree

2) the table might not be as level as it was at the dealers

3) it might be placed on a different surface that at the dealers - actually my first thought. the way the support stand resonates or doesn't resonate is one of the biggest determining factors of vinyl playack. Describe to us how you have your system configured. Some of the "big" mail order places (needle doctor / audio advisor etc..) will have advise and equipment for such isolation.

dont give up...even records with wear can be quite enjoyable. 10% was not an accurate figure :^)

I had a very similar problem before, and it turns out the needle was loose. I still haven't bought a new cartridge...

you have a great system!! Your lp's should be free of almost any noise and not muffed at all. It should sound "better" that it did when you first heard it.

Best fastest soulution is to bring it back where you bought it,
and see how it sounds on that system, this will answer a lot of questions. If everything is ok there, maybe the guy will help you set it up at home. If he is a dealer, I think he will be glad to help you to discouver the problem.

As far as buying used lp's and how they sound. I buy and sell many LP's and rarely do I get lp's that are misgraded and when I do I get a refund. The vast majority sound fantistic, most with no pops or clicks, no noise at all. Some with maybe 1 or 2 pops this is usually dirt. I assume you are buying lp's without scratches because many of these scratches will sound on quiet passages.

Let us know what you find out.
