So I don't get how this does 24bit? I am a 'noob' so I may just be clueless on my understanding of the technical aspects. 

 

DATA SHEET 
TDA1543 Dual 16-bit DAC (economy version) (I2S input format) 
Product specification File under Integrated Circuits, IC01 February 1991 
Philips Semiconductors 
Product specification 
Dual 16-bit DAC (economy version) (I2S input format) 
FEATURES · Low distortion · 16-bit dynamic range · 4 × oversampling possible · Single 5 V power supply · No external components required · No requirement for external deglitcher circuitry due to fast settling output current · Adjustable bias current · Internal timing and control circuits · I2S input format: time multiplexed, two's complement, (Fixed)

 

Nice! So it will have the same chip as VALAB NOS DAC. I hope it will get "the analog sound" that so many VALAB owner been talking about.

Notice that:

 

Play APE will lag.

Cannot play 24bit wav.  Only 24bit Flac supported.

Well, FLAC decoders and compression standards can present their own issues w/ some players.  Don't really want to say anymore, hehe.  For some the 20% compression is worth it and sometimes its not a biggie.  Honestly, shouldn't all players be able to play .wav as a standard and FLAC secondary?

 Only 20% compression? Are you encoding at compression level 1? I've always used level 8.
