Hello Wongpk, I own loads of iPods,I'm a little confused though.
I got my PHA-1 yesterday, it does not work with my 240gb Rockboxed 7th generation classic, It does not work with my 240gb Rockboxed 5th Generation Enhanced iPod Video, I don't know how you will play flacs? maybe convert them to "Apple Lossless"
I've now tried a further 8 (standard) x 5th generation iPod Videos and everytime I get this message....
"The currently attached accessory is not suported by this iPod"
The instructions say only 6th Generation & above... The reason I'm confused is that I saw a picture on the internet of a 5th Generation attached to the PHA-1.
I would say that it doesn't support anything older than 6th Generation Classic.
I don't have Touch with Lightning connector but I do have a 7th Generation Nano, It doesn't work.
As for the PHA-1, with an iPod Classic the sound is incredible, mind blowing and I have
fallen in love with the device, I just need to convert all my Flac to Apple Lossless now....
