New computer has been installed, and will not be recording. As the good old PCI-slot is being phased out and my new pc is lacking one also.
However I decided my trusty 2001 P4, with PCI, in which the card was installed at first, will be put to use for this purpose only. As it runs XP it is not hooked up to any network.
Luckily I also purchaased an S.M.S.L. Sanskrit DAC. Pure for listenig of course. But with what pleasure! Over SPDIF optical with its own power supply (which is a subject to future upgrade..). Keeping the pc-buzz out as much as possible. It does run over USB, audio only, no power issues, but I choose to keep my pc and audio set electrically separated. Both systems have their own surge-protected line conditioners.
I can really recommend these tiny chi-fi boxes. Especially for that price. Bought mine for 100 euros, all new and with warranty. From a nice fellow too.
Will update on how/if the old system comes back online and performs with my old Onkyo receiver attached... And find out how (bad) my old Kenwood Midiset recordplayer souds.
