Yup, I did. With my wifey's Window 7 64bit notebook, it works fine.
Likely, that Win 8 is not supported. Not a real problem since I have a modi/magni as a main rig.
Hi, I just bought my Sony PHA-1, unfortunately, I didn't noticed any difference when listening music with or without the amp. I tried the following
1. iPhone 5 > PHA-1 > B&W P7
2. iPhone 5 > PHA-1 > Monster Inspiration
3. Macbook Pro R > PHA 1 > B & W P7 / Monster Inspiration
Only thing I noticed is when using PHA-1 sound is much louder. I tried to test my music having the same sound level.
The music I tested are all loose less files.
