Yes, doing strengthen the unit, it hums and roars not significantly, but unfortunately holds at least my copy only the right channel, the standardized RIAA frequency curve halfway a. Links are clearly too many ups and too little bass - a test with a Westrex-measuring plate revealed differences of up to 10 dB between the left and right. Stereo playback is not reasonably possible, and Mono plates get unasked a pseudo stereo effect: drums and high-pitched sounds coming from the "Left" and the bass have flip side to the right. Even worse: Most USB digital output, the signal has a noticeable delay difference between left and right (the left channel is offset 2 samples to the right, you can see it in the waveform display eg Plattenknacksern, start always left first, although the yes needle runs over the scratch in the vinyl logically for both channels at the same time). This has nothing to do given the price perhaps exaggerated, audiophile hi-fi claims; the device is simply useless crap and suitable, even unassuming average listeners to mess up the joy of recorded music, it also thwarts any attempt at sounding beautiful digitization. Too bad, because the input level adjuster is a really good idea as pickups from different manufacturers and models now sometimes differ considerably in volume: a Shure M44 system with 78s shellac-needle, or a Ortofon Concorde on a 45rpm- Disco Maxi-Single make fast times 10-15 dB more "steam" in comparison with the more filigree AT 440MLa while playing a classical record, and the output of the conventional non-adjustable phono preamplifier together with a "noisy" pickup overrides any normal sound card line input.
