i’m sorry but i’m not familiar with the philips cd614 so i can’t tell whether there’s i2s data but i believe there should be!

what is the dac chip being used now?

if you modify a cd player, you will not use its internal dac chip anymore, and just tap the i2s data out to feed to the tda1543 chips.

like what i did here. http://diyparadise.com/web/projectsto-keep-you-busy-mainmenu-26/56-a-non-oversampling-dac-for-rm20

the idea of paralleling dac chips isn’t mine. but if you managed to learn about it through my site, then this site has succeeded in its mission. 😀

thx!

I jst owned Audio-gd reference 7.1. It’s 4 PCM1704 UK per channel. Good soundstage, not fatiguing, discrete, good PSU, no coupling cap, precie clock, instruments heard individually, affodable (compare other top brands), violin sounds violin, piano sounds piano. Ths IC is old already but some folks still love its neutrality. Thanks to Yeo. Your idea about to put more than one DAC in pararell inspiry me to pursue same idea. At the beginning I fell in love with Esoteric & MSB DAC but after listening Katty Pery, “Awake” (if Im not mistaken), suddenly I realise those two great names are only in my dream :)))

the 3 i2s lines are SCLK, DATA, WS (or LRCLK). you need to connect these 3 lines as well as GND to your DAC chip.

i explained it in this article here. http://diyparadise.com/web/projectsto-keep-you-busy-mainmenu-26/79-computer-audio-is-soooooo-much-fun
