first of all I cannot really compare dsd to pcm as there are too many things to switch each time. it is not like I can a/b it. I don't think it is placebo but you know how that goes. some people think it sounds better some do not. anyways I am converting pcm files to dsd. furthermore one must understand that much of dsd recording is done in pcm. I do think the final result sounds better even with the required rolloff shelfing. then you have to understand the dac is the same exact thing for pcm and dsd. the actual dac chip is doing mostly the same thing. all the analog section is obviously the same. I really can't be the one to judge. I don't know myself.
then about the pc power cable. yes it can make a deference but the difference is futile. since a pc is inherently not an audio device being a extremely noisy(audio) environment. a $500+ power cable will make a difference but honestly not enough. laptops on the other hand are better at this. they are still plenty noisy(audio) but the psu is outboard or battery which is way better for audio. I just concluded that my pc was better at audio than a ml 390s in another thread. that I am not sure of. the big problem here remains that I must switch the dac input and change settings in jriver. there is no way I can definitively be sure. I think I know what I am hearing but I wouldn't bet my home on it. now something like the ps audio pwd is a computer of sorts without all the noise and actually perhaps better than any cd player or computer.
btw, be careful with that sorbothane .under the mobo. some people use a ton of insulation as well. this will raise temps in the case. it may not overheat it at once but it will decrease the life of the pc form electromigration. if done sparingly it may be fine. I am just wondering if I should use a power cord I have because I think it can be better used on another component than the pc. you can put lipstick on a pig but it is still a pig. the redeeming thing is that a computers dvd/bluray drive is exceptional at audio. too bad the computer is just a emi/rf generator. ok, so what kind of difference did the power cable on the pc make lol. I have a $3,000 cable right here but I do not know if I want it to go on the pc. I could try it but I need some feedback first as my wires are buried. that is why I need a 16 foot usb cable. the computer is right next to the dac but I need to run it down into the basement because there is a door right here.
sorry for long rant. just rambling. I really wish there was a way to tell if dsd was better than pcm. any ideas how to a/b? to me it is so much better I am wiling to do a dbt on it but I could be very wrong.
edit: I am leaning toward 32/384 from the computer is best,the cdp at redbook is a close second and dsd is perhaps third. actually they are all good but different. I can't really decide yet. one thing is for sure, dsd will make a lossy pcm file a lot better. I do not plan on ripping anything so I guess I am using my power cord elsewhere. in fact I may do away with the usb cable reluctantly. since I have to bury it.
anyways, this dac is stellar for pcm or dsd. the sound is obvious because you can see it is built right.
