I was a little concerned about buying it because one user complained of a humming noise from not being grounded properly, but it worked great.

Unfortunately mine made a quiet high-pitched noise whenever the usb cable was plugged in

I get some crazy background noise.

I think that the instructions were hard to understand and I still don't know how to fix 'pops' and unwanted noises.

I tried several albums from my collection and was pleased with the sound reproduction-no extraneous noises

It seemed fine!I plugged the sucker in, and it started making a humming noise.

The opening riff of Sweet Child O' Mine sounded great!Opinion:For $130, this was amazingly good

Good s***.

Very clean design, wonderful sound e very sharp during the operation
