Accphoto,  
 
Are you using the USB format for your dac ? If so, try to disconnect other USB devices such as trackpad, mouse, etc. and playback an AIFF file to see whether the noise got removed ?

I am using Macbook as CAS at the moment, still not happy with the background noise......Look like that Notebook +SSD+ no switching supply may be the way to go.....  
------------------  
 
what kind of noise are we talking? electronic noise?  
i don't find it a problem. in fact i find the difference between a desktop and a portable is quite significant when i do FFT analysis. the FFT is so clean using a portable it is quite unbelievable even with a not so good ADDA.

still it is not enough for the media library. you still need something kind of NAS. but ssd for the system should cut down the noise. however i think going to portable has more significance in reducing the noise.

Thanks so much for the info. I'm quite out really.  
 
Wait, when there is solid state disk, there ought to be tube disk that is likely to sound better, isn't it ?

my current 'clean' version is v0.9.5 how's yours ?  
----------  
i'm running 0.94 i think. it happens once in while. it just happed on monday when kris was here. after he left, i move back to the centre seat and found the sound shifted to the right. i naturally thought it was the emu dac i'm using that caused the problem. after a number of debuggings, i reboot the system and the sound comes back to normal. this happens before but i don't have the luxury to listen to system for so many hours.  
 
what does SSD stand for ?  
----------  
it stands for solid state disk. pure electronics and no mechanical moving parts in the hard disk. it is not something new but it becomese more affordable now.

SSD - stands for Solid State disk, 即固態硬碟。好似 RAM 咁樣無須要像普通 hard disk 咁要用頭去讀 data (接觸性),又免卻 hard disk 既 motor noise 又慳電。  
 
呢個係趨勢, 32G 價約 HKD740, 64G - HKD1250, 128G - HKD2500.....

>>>the sound shift to one side. and i need restart the pc to fix that. very strange!  
 
That's really strange.... I run my foobar 24hrs a day/7 days week continuously to burn-in my gear and doesn't cater the said defect. The only drawback in my case is cannot run the new version properly, my current 'clean' version is v0.9.5 how's yours ?

BTW., if using CPlay, then I think it doesn't matter to concern the SSD since it loads the song/wav file to RAM before playback. Or just use SSD for OS/system file is more effective.  
-------  
actually you can configure foobar to do that as well. only problem i have with foobar is that if i use it for too long in terms of hours, it loses the left and right balance. the sound shift to one side. and i need restart the pc to fix that. very strange!

Doctor is right !  
 
A notebook with 128G SSD instead of hard disk is the best.

Buy yourself a Mac Mini is the most suitable expense.

我只是覺得 DVD-A 是玩高清音樂的一個踏腳石,遲早都會 fade out。  
 
如肯接受用電腦 > dac 的話就當然最好。

不過我們此等自作派就特別喜愛玩多 D,蓄多 D,所以 dd 有那麼多 vintage amp., jcml 有那麼多 digital player,我就咩都玩下。  
 
或者我比較貪心,不論 LP, CD, hi-res. wav/AIFF 等都照單全收。亦希望全部都玩得好聲。

If you think a mac mini is still too expensive, get yourself an apple TV (iTV) with 160GB with remote and digital out at HKD3000. Sync everything from your pc to the iTV including youtube and what not and hook it up to your super DAC. Then you can play and organize whatever you want, hi-res or hi-def, on screen.

And thus, as quoted by dd845, DVD-A 是其中一個較好的可行方案. Obey our DIY spirit to homemade DVD-A with hi-res. source is also a good start....just my 2 cents.  
----------------  
i don't find thisattractive at all. look at it this way, we still have tons of cds to listen to. high def source is coming and it will not if ever catch up with cds in any time soon. and upsampling for the cd to whatever is just like breast implant. it looks good on the outside only.  
for those who don't want to mess with pc, mac i think can be operated with a decent remote control and probably ipod as well i think. this can be used for both traditional cd and high def stuff. dvd-a i think is pretty dead. i think the future will be computer based so normal high def wave file will be the norm for audiophile at least.

dd,  
 
Since dvd-a player performance is limited by it's dac design, w/ HKD4.7k you can buy an Apple MacMini that comes with a remote control and support both firewire or USB for external dac.  
 
The most attractive point is, it's tiny, tidy and nice looking is very suitable for your tidy living room.

>>>get a mac if you don't to mess with pc with a couple of T harddisk. and get a decent usb dac.  
 
Agree. But iTune got some issue that need user to manual select the sampling frequency manually. To sync. sampling frequency to match the sound file type, some software such as Nueno or Wavelab are better choice.

i can tell you what not to do. whatever is proposed in the other forum about superduper computer and clock, upsample to the infinity and beyond. get a mac if you don't to mess with pc with a couple of T harddisk. and get a decent usb dac.
