Wink My media pc setup

Hi.

I am building a media-pc. (Same design as my BoSoZ in this thread)
- Link -
The main use are for playing music through a USB-Dac.

I am just getting ready to installing some software for it, so it could be used as a kind of 'lite' media-center too.

I now, that foobar2000+ASIO4ALL are used as a reference for playing through theese DAC's, making bit-perfection and no interferring from windows mixer etc... That's fine, but I would really like to use Linux as the OS for my machine, as I think a media-pc program like freevo, is better for me than the winXP media-center. But that's not my point at this thread, I am searching for a way of playing bit-perfection and with no mixer interference with Linux (mplayer or whatever), but can't find anything about it on google.

Hoping someone here know about Linux capability of playing with USB-Dac's and maybe answer some of my quistion's ?


The LCD is green with 4x20.

Very nice lykkedk,

I'm in the process of doing the same thing, however, I am going to use XP. I love Foobar. Great player.

Sorry, but I don't have an answer to your Linux question. I'm sure others will though.

What is the interface for your LCD display? What does it show?


-Ken

very nice case!

Try Amarok which seems to be the new audio app of choice for Linux. I tried it when I attempted to go Linux in 2001 (when my Win2k kept crashing) and Amarok seems to have come a long way in its development since then, judging by the nice screenshots on the site. No idea about sound quality though... One day I will try to give Linux another try.

I'm still stuck on windows, and am very happy with J River Media Center. (screenshot below). Browsing by album covers makes it very family friendly. Used it for a long time, it was once very buggy but it seems very stable now, is regularly updated and their forum is very good. think it costs about $40. Quality wise no difference to Foobar as far as I can tell.

Well it's been a while, but here in christmas i throught i would post a picture of my setup.

Here it is then. And a merry christmas to all of you, here from
Denmark.

Yesterday i tried making a comparision between an Pioneer A-91D, and my BoSoZ(unbalanced)+Leachamp. Both coupled with my Freevo linux media-center, and a DDDac with 1 tower. (Very good thanx Doede). Maybe I am wrong, but the first impression, was that the Pioneer, was able to play louder ofcause, but the sound, it was not good compared to my diy-setup, no joke, more life and cleaner sound is coming out of my diy-setup, I never tried this before, but gladly surprised i am.

Reply's and comment's are welcome.

Motherboard: VIA EPIA ME6000, passiv cooled from vendor.
HD : Hitachi 123GB 7200rpm (Very silent)
PSU : Passiv cooling Modded old PSU.

I have placed 2pcs. 80mm fan's inside, which i slowed down to their minimum, to make a little air-flow.

When putting my ear to the box, i can hear the HD and the 2 fan's, but when moving a little away, there is silence.

On the HD i have nearly 200 CD compressed with EAC/.FLAC. The system is ubuntu linux + freevo media center.

Very cool. I built a media center based on Win XP pro and use J River Media Center (which I still find to be a little buggy) If I were to do it again today (and I will eventually) I would definitely use Ubuntu and either Freevo or Songbird.

I also use this machine as a dvr and it is based on an Asus mobo with integrated video and sound, (sound not used) an athlon xp 2600, 512MB ram (I'd use 1GB if I did it again) 330GB total hard drive capacity in an Antec Aria case. Audio is delivered in spdif format to an external dac using an m-audio audiophile 2496 sound card. I use asio exclusively for audio apps - don't worry about it quite so much for dvr apps.

The Aria case has a very large low speed fan, and was extremely quiet until I added the 250MB second hard drive. I recommend buying one really large drive (>250GB) to start. It is still quiet enough, but I would estimate due to the poorer mounting isolation of the second drive that noise increased about 6dB.

The drives are both seagate 7200rpm 100MB/sec drives. Notebook drives are smaller, quieter, and cooler running and in most systems are adequate.

Most current sound cards and onboard audio resample in hardware to 48kHz, the m-audio and chaintek avs-710 don't. Both support asio.

Audio media is encoded exclusively in flac.

I recently "upgraded" from a PS Audio Ultralink II to a Zhaolu 2.5A. (Yes, surprisingly it actually was a BIG improvement, despite the loss of HDCD decoding capability.) This allows me to support any bit rate up to 96kHz (limit of the 2496) at either 16 or 24 bits.

All of this was to replace an ailing PS Audio Lambda Drive..

The sound quality is excellent incidentally, at least on par with the Lambda as a source.

I use a spdif transformer and common mode choke to isolate the server from the dac - avoids a ground loop issue and also strips a lot of high frequency noise off of the spdif line.

See my old media server thread for more details. (It's pretty up to date on configuration of my server.)

I can simultaneously listen, rip and encode in J River and record a tv show in SageTV with this server. It's pretty fast..

Edit: added a few extraneous details.
