Sorry to hear that. While I have not had any troubles with mine in the two days I've owned it, I did experience some frustration in just getting it.
I ordered mine from Micca Distributors (through Amazon) so that I'd get the free toslink cable (which is VERY nice quality). I ordered it on January 31st, and it was supposed to be delivered by February 11th. After it did not arrive by the 12th and there were no tracking updates since Feb 1st, I began to panic, so I contacted the seller that evening. In less than 2 hours I got a reply. The woman from customer service said it must have gotten lost by the Postal Service. She asked me if I wanted a refund or for them to ship another package out to me. I told her that I wanted to try the amp really bad, so asked her to please ship me another one. The next day she sent me the tracking info for the 2nd package, and I have to say I was very impressed with the great and speedy customer service!!
Anyhow, the amp arrived on Wednesday, and I immediately opened it up and charged it. I have tried it with several different sources, from the optical out of my desktop PC, the USB from my laptop, the optical out of my Yamaha DVD-S2500 Universal Disc player, and the coaxial out of my Sony BDP-S580 Blu-Ray/SACD player, and it sounds great with all 4 sources. I would have to say that it is everything all the owners have said it is. Everything about it screams quality to me, from the packaging, to the build quality, to the great features, and most importantly the sound. In the 2 days I've used it around 10 hours, and the battery meter still shows it has a little more than half of its charge remaining. After getting it going and making any EQ and volume adjustments, I put it in hold mode, assuming that if the OLED screen was always on, it would significantly reduce battery life. Anyhow, my AKG K240 MKII's love this little gem of an amp as much as I do, and I couldn't be more happy with this purchase!!
Now, getting off topic a bit, can anyone please tell me why I can't upload pictures and change my avatar? Is there a minimum post count before one can do so? I tried to find info on the forum, with no luck. But I have seen others with between 10-20 posts that have changed their avatar. Thanks in advance!
