[One star, because I only purchased the unit recently, and have not had enough time to really put it to the test, but I was not allowed to post anything without choosing a star rating, and I personally think star rating are useless. So, the one star was for their insistence on that, and nothing to do with the turntable. I might be likely to rate the turntable *after* I've lived with it a while, and can speak to actual pros and cons.] I'm curious how many users have found that the "Line" setting provides a cleaner signal than the "Phono" setting? I have three receiver/amplifiers, two of which are identical, and have phono input jacks with a ground terminal. When connecting the LP-120 to the phono inputs, with the the turntable switched to "Phono", a nasty buzz is present. When connecting the turntable to any outputs on any of my receivers, with the switch set to "Line", the signal is clean. So.... is this something that other users have experienced? Additionally, the turntable provides a clean signal when switched to "Line", and connected via USB to any of our computers, and also to powered monitor speakers in the studio. This makes me curious about the built-in pre-amp, and why the "Phono" setting creates a buzz when connected to receivers which are designed for phono inputs?
