I would never confuse any other amp with a legend like that.
I'm thinking it's one of those different area market things, or the more likely scenario of them calling it the wrong name. I have this issue buying stuff from Japan all the time. He is saying it's a PHD "ART2075". Here's what I remember: 2ch, single 30 amp fuse, grey case with PHD logo engraved on an other wise smooth, kind of shiny top. Heatsinks all the way down the two sides, power and speaker terminals are pretty basic and on the same side as each other. There is a matching "ART4060" that I can get with it, I guessing it's pretty similar but a 4ch
I'm really sorry I don't have a pic to make the Identification easy, I'm just going by what I remember. Thanks in advance for your help.
