While I echo @cleeds observations regarding convenience for me the real benefit of the us cleaner is how it improves the detail and resolution in LP playback. I used to own VPi and ClearAudio vacuum cleaners and the best thing these did is clear the record. My KL Audio actually changes and improves the sound of the LP, even those that play and appear clean. Whether this benefit is worth it on your system is for you then decide but the investment you make now will pay back as your system improves
if I buy an ultrasonic cleaner for my records will I be able to hear the difference?
I have a lot of records and have cleaned some of them with a VPI vacuum machine. My system is quite nice but not ultra high end ( turntable about $2K and the rest to match) .Will I be able to hear the difference , with my system or is it just for those who can afford the very best?
