I've just purchased a Pro-ject Headbox II SE Headphone amp and there appears to be a dearth of information and reviews about it.
It is being used with a pair of Grado SR325i headphones, my source is a Sony SCD-XB940QS SACD/CD player via a Sony TAFE940QS amplfier (Tape loop)and a Van Den Hul Thunderline Interconnect.
I'm delighted with this particular combination but I'm just wondering what other more informed people rated the setup-particularly the amp?
