This is the 2nd. Teclast device I own. I have had the T39 for nearly a year I think, prior to that I had a Teclast C260 which ended up bricked for some time – after buying the T39, I actually managed to fix the C260 by following some un-bricking guidelines from the interweb.

The T39 has been the best MP3 player I’ve ever owned and also a great MP4 player as well. I started with MP3 back at the turn of the millenium when MP3 CD players were available – back then, the device had to be catered for. You had to create the MP3s yourself with a certain filename format (8.3) and put them into the ISO9660 filesystem with care in order to ensure you could navigate with just a digital numeric display capable of showing numbers up to 99.

These days, I still create my MP3s, but I use Grip, which can lookup labels for me. The T39 is just great. It had some initial issues with firmware, but now its stable and very usable. The main reason I can’t replace it is its sounds quality. I now have a PSP, but its nothing compared to this thing. Its easily as good as a home DVD and arguably, using a lithium battery provides the clean power that a high quality device thrives on and this would beat most home DVD players in audio reproduction for that reason. It’s software supports formats like FLAC with good reason. I still choose to make high bitrate MP3s, since I can’t tell the difference even with the good headphones attached (good being Sennheiser HD650).

I think it gets around 100 DB of S/N ratio, which is just great. The amp is clean and powerful, able to drive the HD650 cans to comfortable volume with no distortion.

I had a lot of fun playing with movie creation on this device, for it is capable of delivering up to 30 fps AVIs – however, through playing with it, its actually best not going above 25 fps. At 25, it can play 95% of video with no loss of sync, and with the new firmware, if it does lose sync due to lack of cpu speed, it finds it again by itself pretty quick. This means I have become quite adept at doing things like de-interlacing NTSC films down to 23.976 and adding a little noise to increase pattern perception with a smaller color palette (18 bit)

I will probably publish some of my perl scripts here at some point, along with my PSP movie conversion tool that makes use of mencoder and ffmpeg. The main thing I achieved was the ability to down convert from 25 fps to 23.976 by remuxing the video with appropriately down-sampled audio automatically. My PSP only handles NTSC framerates.
