Daniele, I am a little confused by the model #. I own a Melos 222c preamp with built in phono section and separate power supply. I am aware of a 220 phono section and a 210 line stage; never heard of a 200. In your comment you suggest that "looks like the phone section is great". So, it has a line stage and phono section? Is it in one chassis, or does it have a separate ps? Are you sure you are not to referring to the 222?
Anyway,I know the 222 very well and have heard the 220 phono section. I agree with Steuspeed re the build quality (adequate at best, although the circuit board, layout and parts are good). But, I disagree with him about the sound. They are fine sounding pieces and IMO a least on a par with the AR pieces you are comparing it to. They definitely benefit from good tubes as far as noise is concerned.
