回覆 (601): CAS DAC
 
 
Probably because the battery is working on a higher charging voltage of 11V rather than the nominal 9.6V.

limage,  
 
win7 is not running in a VM and using bootcamp (or a dual boot system).  
 
you can't always have your hardware working right under a virtual machine.......

Sir CP,  
 
The curious thing is, the laptop does sound better when I have the AC cord attached. Running purely on battery lacks the weight and authority even though the battery is fully charged.

>I was told Foobar is inferior to JPLAY !! 8^)  
I was told copper is inferior to silver too :-)  
I think all open source player can be good and bad, I know nothing, I just think it has become spending too much time messing than sit back relax and enjoy music ....  
 
Come to think of it, I may have to agree w/ dr. K, VMware probably don't support all the stuffs win7 ask for .... Still a low cost waste of time game ....

would it then be a good idea to use a desktop with arguably a bigger and probably a more stable power supply?

All desktops use switching power supply. Laptops use batteries.

The Mac Book Pro I am now using is on loan from mdlover. It has exactly the same feature you have in mind — a two-in-one chassis running both Apple and Window 7 and yes, Foobar installed as well.  
 
Let's see what you get from your venture. It's not exactly ab comparison as I have to turn one off before I may operate the other. Up to the moment, I prefer the sound from Windows.

Use a Mac book pro ( or similar), partition a vm with window 7 and load a foobar player, wonder if that allow a/b comparison ....  
----------  
i would advise against this. the driver produced by mac for window is rather lousy. you will likely have latency problem.

I am no expert, but some believe the model no of the MAC also affects the sound and this does not mean the latest version is best ! @@  
 
BTW - I am also feeding my DAC direct via my macbook pro 8^)

What I try now is CAS in a nutshell: a MacPro feeding a DAC which is capable of handling virtually every format available in the universe.  
 
Does the power supply of the computer have much effect upon the output digital signal?  
 
If yes, would it then be a good idea to use a desktop with arguably a bigger and probably a more stable power supply?

聽了DSD嗎?  
______________  
 
聽了,但不太好。這兩天很細心的比較,發覺用什麼制式其實不如想像中那麼重要,好與壞原來依舊取決於原錄音的本身。  
 
在未有上榜名曲的高清版 master download 之前,CD, DVD, DSD, SACD 等等似乎並沒有"天與地"的分別!

It will come around quickly with your skill, experience and dedication. When you start using an iPad or similar to select your music from your entire collection without getting your butt off the chair and the sound quality surpass or matches any CD/DAC (& is here already), there is no return. Messing with a turntable truly become an art form, almost like 茶道 vs just 飲荼.... When I was a kid, I want a juke box, I got one now.

As I found out earlier this week, even when the DA chip in the DAC is different, they can sound awfully close depended upon the implementation. Those 3 I have on hand  
Transporter use AKM AK4396  
Cambridge DacMagic use Wolfson WM8740  
Aneroid use ESS ES9018  
 
When it was driven by the same player software (squeezebox) over Spdif input with careful volume matching, their difference were sometime obvious and other time subtle depended upon the material. I was able to fool our listener a few times on blind tests. However, when we connect them directly over USB using foobar player, it become quite different, the DAC signature sound become more obvious. When c-hing start up sample the source (foobar has a real time up sampling plugin you can download) going into the DAC, the level of performance become even greater!  
 
My observation was, the interface plays the greatest influence on the sound follow by the player and how we mess with incoming sampling of the source. When you start looking at price point, how do you begin to value those less than a thousand dollars DAC over those dcs, msb players ? I can't wait to see in a few more years what's going to happen with technology, implementation as well as those big-time manuf.  
 
this has become a lot of fun and frustration ...

Making use of the holidays, I cannot wait to try out the variations. One thing rather disappointing. Downloaded flac files from the Decca website do not sound as good as ripped files from the CD. Perhaps I’ve done something wrong, perhaps the files which took me 2 hours to download were contaminated. Perhaps there are unknown factors I have yet to discover………  
 
Anyway, Merry Christmas to Every One!

Suffice to say that I could not quite distinguish the difference between my CD player and CAS on the same piece of recording, provided the volume level was carefully balanced.

咁橋,呢個週末友人借我兩部價賺物美的DAC (Cambridge DacMagic, Aneido D2), 加上我好友(Kuro)撫到七彩的Transporter!Busy busy ... 我唔係想講或价詔呢兩台机,你哋可以慢慢Google Search (they are quite nice),己係我有感發現今個年代發燒真係已經轉型, 以前換下唱針,挍下VTA,到後來換線,挍電,燒到不亦樂乎, 加時啲師兄係改Window七 OS, 改CPU setting,轉Power consumption, memory utlization, swap, upsampling 等等.等等,改改,聲音真係有變喎。我想我哋死晒之後仲有無人撫唱盤唱片?? 我地不生的LP collection有點另下一代明白同去保值 ??。
