Did anyone compare TP with another minimalist SD card player such as SDTrans 384 by any chance?
The answer may be yes when a project in diyaudio emerges. The SDTrans 384 developed by two Japanese Chiaki and Bunpei.
It's an ugly DIY looked thing with a beautiful design and implementation. The rationale is simple, minimalism.
8 bit MCU+FPGA+ultra low jitter oscillator+SDCard reader=SDTrans384.
Lowest voltage is required, only 5v.
As a result, no stupid bulky os, just configuring FPGA. SD card stores huge amount of CD's but no vibration at all at time of reading.
It can read PCM files(wav only) and amazingly DFF files (DXD) in native form, as different from those converted into PCM.
It has no DAC. DAC is another topic. Remember even traditional CD player splits down into two parts, CD transport and DAC.
SD Trans 384 demonstrates the possibility of good standalone digital music player in the simplest form, a perfect replacement of CD players.
Quality of music playback is at least comparable with good CD players on red book format, if not better than.
Sadly though this is just a DIY project already finished, yet many want to see a commercial product building on their design.
So far majority of them should be sold domestically in Japan and here is a thread with discussions in English

Just thinking out loud and wondering what would inspire Charles to work on another "Altmann Peta-Player" with 1-bit/2.8MHz DSD support.
