Any LP I played on my new TT Sony PS-HX500 had the same channels imbalance: L channel +1.5dB. Cartridge perfectly aligned with a mirror protractor. Anti-skate the same with the VTF. Wrong azimuth I thought. OK, let's fix it. But the TT tonearm is a cheap simple thing with no azimuth and VTA adjustments. After some research I found a DIY method suggested by Mr. Peter Ledermann from Soundsmith. So I cut a thin plastic card and I put it between the tonearm headshell and cartridge, on the L channel side. Now channels are almost perfectly balanced (L channel +0.01dB) and I full benefit from the 30dB channel separation. Immersive soundstage. Tested with Azimuth tool from RX 6 for an entire LP. The VTA adjustment, because I replaced the stock conical "made in China" cartridge, was quite simple. I replaced the default Sony 5mm rubber mat with a 3mm cork+rubber mat. I think a tonearm with no azimuth and VTA adjustments it's a shame. I don't understand this manufacturer paradox. Why they put a high quality industry level ADC for audio recording on a junk TT?
