Memory playback worse than disk... Why?

Hi,

I'm used foobar, now jriver to connect my new toshiba portege r830 (i5,4g ram, windows 7 64-bit) to my Dac via USB

I play 24/96 flac files, stored on a buffalo nas.

To even get close to near absent jitter, I use wasapi event mode (better than ks, wasapi,...), exclusive mode for Dac, and clear the buffer before each track. I also increased the priority if the jriver process.

When I elect to playback my files from memory (file uploaded prior to playback), I get these big crackling noises upfront, and experience more jitter than by playing direct from the nas disk. Why?

Poor laptop design, windows design, settings ?

P.s. I'm amazed how complex it has been to make 24/96 work (and it's still not perfect).

I have experienced exactly the same phenomenon you described (just effects are minor). I think that Davide256 is correct in that wasapi seemed hardware buffer link.
I solve this problem and improved sound quality by using ASIO and not wasapi or wasapi special.

In addition, FLAC sonically is bad format and will increase all artifacts too. why not to use WAV ? if everything else is set up correctly you will hear immidiately big difference bewteen two formats ( I use powerful computer also)

" FLAC is not a bad format. It's just 1's and 0's."

When did I hear identical argument????
Oh in 1982 when CD Players were introduced...

People must go more frequntly to acoustic concerts and/or wash with soap their ears so they will know what they HEAR not what they read in smart manuals.

" Don't blame the format if your computer cannot handle it.
"

Should I comment? Did I disclose to anyone (except Alex Peychev of APL HiFi) my computer? Nope! I will be silent like a fish!

Just tried to help OP - I had identical problem, solved it and explained how. Also not good; somehow stepped on some egos.....Brrrrr

Oh, if someone wants to use lossless compressed format then APE is much better sonically then FLAC. Particulalry with hi-rez (e.g. 24/176.4) files. The 16/44.1 is really not a challange today
