Hi guys,
I am one of the early users of linux, started using it in 1994 (Slackware distribution) and since then as a hobby has installed at least 50 different distributions in my desktops and laptops and others' also. While as an OS, I like it much much better than anything that Bill Gates has had on offer, it is quite weak in multimedia integration. Almost nothing works initially, and after a lot search on the net, reading multitudes of discussion, a few things work. Even simple things like printer drivers with duplex support are missing.
That's why on my last laptop purchase, I went for Apple Mac. The OS is based on pure Unix, but the interface is extremely user-friendly. If you want to use unix commands, you can do that on a usual Mac terminal or X-window, or if you want to just use your mouse for all work, that also you can do. Integration of all applications is top-class. Since I use it mostly for my professional work, I have not fully tapped its potential for multimedia, but reportedly it's very good. And guys, no virus, no worms etc. The only downside is its price, on the higher side.
On Dacmagic and Beresford USB dacs, I have not heard the Beresford, but I have heard the Dacmagic with a Cayin 50T tube CDP as transport. I did not like it at all. I have mentioned it elsewhere. The sound was not open at all, as if some veil was put on the speakers. The accompanying equipments were all reasonable, so cannot blame it on them. They were Quad 99 pre and 909 power amps, Epos M12.2 speakers, XLO interconnects and coaxial cable, Ecosse speaker cables. I have already said that the CD transport was very reasonable too.
Of course, the above is my personal view. May be that particular unit had some problem or was not broken in properly, whatever. But, moser, if you want to buy it, please audition it seriously before you make your decision. On the basis of my audition, I would not buy it for 20K or more.
There is a news that Musical Fidelity has come out with a DAC called V-DAC for USD 299. Initial impressions are very good. See the site
The Little DAC That Could | AV Guide and also follow the discussion at the end of the report. People are mentioning yet another cheaper DAC from PS Audio (Perfectwave DAC).
