Hello, all. It's been a while. I've been so content with my little rig for so long that I simply haven't felt the itch and fell out of touch. [ FiiO X3 (1st Gen!), line out --> JDS Labs C5 --> Sen HD600 ] But I just noticed that JDS Labs isn't even making a portable amp anymore. So I started doing some reading, trying to see what's out there these days that I might like. I quickly came upon the FiiO Q5 of course. It's new amp architecture and near universal raves really got my attention. I had the E12 for a while before replacing it with my C5. I found the E12's high end a little gritty and also a bit too bright. I far preferred the C5's high end, detail, and overall smooth sound. So do any of you Q5 lovers happen to be former (or current) JDS Labs fans? What are your relative impressions?
