I have the Ultrasonic V8 and the Vpi 16.5 and I only have positive things to say about both machines. I have been able to make many records very enjoyable again.....I have not noticed any degradation of higher frequencies on any of my vinyl but I am 53 and hearing is still good but not like it was 20-30 years ago......my system is a Clearaudio Performance DC with an Ortofon 2m black cartridge. I would recommend either machine or a combo of both....
