Running a Sansui 9090 DB, Thorens 165 with V15Vx cart, into JBL L100 Century. I recently bought a Pro-ject Phono box MM. At first, I was pleased with the volume boost and music sounded different ... So I’ve been on a MFSL kick lately and was playing Beck’s Sea Change. And there it was once again — crackle and crispies. It seems ever since I got the preamp, records are full of crackle! Know that I had just cleaned Beck album with spin cleaner. and used zerostat gun. So tonight I had had enough ... was the preamp producing a boosted, yet more artificial sound? I unhooked the preamp and tested my system using original built-in. I must say it seems more real. I would sacrifice a volume boost for fewer crackles and noise. Any thoughts??? Am I an idiot for not liking the cheapo preamp? Any validity to preamp producing more crackles? thanks!
