Well, I would just take the analog output from the computer and feed it into an amplifier and hook the amplifier to the speakers. Just get a cable that has the 3.5mm stereo plug on one end and RCAs on the other.
Most computers have Realtek AC93 codecs, which are 16-bit, either on the motherboard or soundcard, and it works just fine. I feed mine to Audioengine A2 speakers, which are pretty good, and have also tried feeding it to my expensive electronics and speakers, and it is surprisingly good. It's not as good as my $6000 Ayre C5xe/mp SACD player, but then not much is.
It really depends more on how good the CD/DVD drive is in the computer, if that is your upload mechanism. Other sources obviously vary in quality also.
I have a Theta DS Pro Basic 3 DAC, which cost over $2000, and the sound using it is not really much different from what comes right out of that little 3.5 mm stereo jack on the computer. The Theta is a little better; not much.
I have a $25,000 high-end system in my living room at one house, so I am not someone who is easy to please.
To drive those speakers, I strongly recommend what I am using in my big system; the Bryston 3B-SST amplifier, which runs about $4000 now. I am using it in my big system with an Audio Research LS-26 preamp and Vandersteen 3A speakers and subs, and the sound is to die for. No compromises there whatsoever. Another great amplifier is the Musical Fidelity M3i for $1500; very very good for the price.
If you REALLY want a great DAC, you could do worse than a Theta DS Pro Basic 3 or 2, which cost $1500-2500 new, but can be found for under $700 used sometimes.
All this chat about the Vienna Haydn Grand is kind of dumb, since the OP likes them and is going to use them. If you ask me, they are very good-sounding; every bit the equal of the Sierra 1, which I have listened to a LOT (at a friend's house), and find reasonably good-sounding but IMO somewhat overpriced. at $900, they are only the equal of the PSB Image B6 and other speakers in the $500-600 range.
Audio Research makes an excellent tube integrated amplifier for $4500, if someone is into tube power amps.

Now i am running this with Nuforce Usb DAC2....i thought it deserve a better upgrade and it was time for me to upgrade the DAC..
So right now i am in middle of either buying Peachtree Decco2 or Music hall 25.3...
Also what kinda amp you guys refer for this speakers...right now i am getting Marantz MA 500 Mono amp...
so this is the current setup...
PC->Nuforce Usb2 DAC->Marant sr6005 (as amp) -> Vienna acoustics Haydn
PC->peachtree decco2 or musica hall 25.3 ->Marantz ma500 (2X)-> Vienna acoustics Haydn
much more future i might be moving towards Yaqin Tube amplifier...(cheapest one to start the tube world in )..in that respect i was thinking to keep 25.3 and change the tubes and then i have preamp as tube and then add yaqin as amplifier later too..
Any recommendation or suggestion you guys suggest....
