I'm planning on trying out the KZ T1 myself. If indeed the AP80 and it are a match, I'm definitely stoked.

Is this normal, I'm downloading the AP80 USB DAC drivers but PC detects something in it as a virus?

I noticed it's very hard to carry around the AP80 in my pocket as the wheel get's easily pressed and I often accidentally turn my device off while moving.

I did. The AP80 just reached it's 20k files limit and did not index the flac folders.

I loaded my microsd card with 117gb worth of files...the file list under "Format" does not list my FLAC files. Only m4a, mp3, ape, wav, and wma. But I can navigate to my flac files thru the "Files" tab/category.

Got mine yesterday. The case is too snug, too tight Bought this after my Clip and Clip Zip died last month. Both popped open on their own because of a bloated battery.

im a recent owner of the hd661. you must consider the comfort issue...the clamp of death is real. but mine eased it's fit in about two weeks. i just stretched it on a pillow when not in use. now it's much more comfortable to wear...

My sanity preserver. Sansa Clip Zip, Superlux HD661, Fiio E6
