Well, I used it for a while. It's very versatile in that both gain and resistive loading are accessible from inside (so you have to keep the lid unscrewed for a while). The phono operates well and its curve is OK. It's a bit bulky, but you can conveniently hide the PS if space/looks is/are an issue.
The output is well thought out and allows you to drive the next stage --whatever it is-- quite easily without losses.
OTOH, it was a pain to set up input correctly partly because my cartridge manufacturer is somewhat cryptic about the actual characteristics of the cartridge (which he has somewhere anyway -- it's numbered) and because the instructions on the ASR need (or needed) a PhD in extrapolation to understand what the H is going on...:) I.e., how gain correlates with Ohm, how exactly the dip switches operate etc.
I also found that ICs often impinge a small sonic signature of their own -- even though ASR use excellent quality components in their product respect.
If you are satisfied with the sound CHARACTERISTICS, you could live with this product for a very long time. Of course, don't judge by a quick, on the fly, loading; any improperly or suboptimally loaded cartridge/ phono combo will sound awful and it's neither the cartridge nor the hpono equaliser's fault:)!
