I have one, and connected into my ARC Ref1 Pre, I really liked it a lot, but the ARC was a great tube Pre. I also have a Audio Technica.
I own a Shindo Masseto, so I have everything I want built right into the Preamp.
If your still looking for a Grado PH1, PM me, I have the box paperwork, good condition. Would be great if it found a home with a "Goner"
