Pass D1 - using i2s input

i have tried this USB to I2S card too too feed my PMC63K dac and i'v got mixed feelings about the result .

yess it works perfectly , and you can use your dac till 768K with the oversampling made with the filter of your choice using HQplayer .

it will probably mesure better but for me the timing is wrong all seems too fast or stressed , oversampling Non oversampling trying tons of filters apodizing , non apodizing just few seconds listening to human voices or wood instruments tell me that this something is not right .

so finally i have the returned to SPDIF and the sound i like is back again fortunatly the JL Sounds card have a very good Spdif outptut.🙂
 
@juanitox - did you have separate supplies to both sides of the jlsounds card? I was listening to this DAC last night, and certainly it sounded great, without the issues you mention above.

I had the WM8804 receiver etc, and I thought direct to i2s was just a little superior to SPDIF (which was surprisingly good).
 
yes i have separate usb side and reclock power supply , just to clarify my PCM63K dac sounds very well with I2S direct in place of CS8412 and D1700 digital filter well knows are so-so chips but they was made to work with this Dac . i also have a Holo dac with R2R with femto clock DSD oversampling x1024 , PCM 1,5MHZ and all the the bells and whistles. and the PCM63K with I2S input sounds very close to the HOLO . But.... at the end i prefer the vintage sounds less artificial to me , it s just a subjective point of vew or perhaps just a " madeleine de Proust " effect.
but at the end i listen most of the time with the PCM63K in SPdif ..
 
Someone further back up in this thread had a similar observation - that once you bypassed the filter etc you are no longer dealing with the same DAC, so I wouldn't argue with your comments. In my case, the DAC is not so much a clone as an interpretation of the D1 - while the DAC front end is the same as the D1, the IV stage in this one is different, and of course layout etc will all also be different.

Put another way - it is nice to have the choice to pick either SPDIF input through the filter or to go direct with i2s to the chips depending on what sounds best to you. There's no bad side here!

exactly same notice on spencer d1v3 . jlsounds very edgy dry and shouty midrange . its faster than wm8804 . it took me some time realize that "upgrade" downgrade. after mod silently abandndoned dac which was overhelmed with other dac's in my colecton. after 5years i put wm8804 back, feed spdif with good converter and magic is back. 🙂 btw jl sounds converter using as usb spdif still sounds pretty much the same - fast, detailed with good midrange texture, but lof of stress, and shouty mids.
 
I hooked back up the D1 clone again tonight, just to double check the sonics, based on the comments from yourself and elviukai.

All I get is clean, natural sounding sound, great depth and detail. Maybe not the widest soundstage ever, but most stuff I've tested with here is simpler mic'ed material. Definitely not shouty midrange or any hardness for sure. In fact, I would say its forgiving enough of the material you play. No fatigue either. Of course this is all subjective with a capital "S"!

By comparison, my early version buffalo (ess) dac gives a wider soundstage, and perhaps a touch more detail, but its also "harder" sounding. I guess its trade offs on all parts.

I'm using a linux distro for playback, see wtfplay-project.org on a basic enough asus laptop.
