I'm not specifically concerned about upgrading, but I'm getting a new sound card since my STX kind of died on me (I'm getting a free replacement), so I was just curious if there is any real advantage to going with the more traditional DAC setup. From what I have read, I don't really think so, but I haven't explored much outside of "sound card" form factor.
I like my headphones most of the time, but I tend to use my speakers for playing music when I'm not at the computer or when I'm watching videos/shows.
At this point you might want to get a high end DAC or a professional sound card like RME or Lynx, RME does make the Babyface which in my opinion produces excellent quality sound, look it up.
There are quite a few on Craigslist right now, or you could buy new with the excellent warranty.
RME: Babyface
You will have to take a dive in learning how to set up TotalMix FX and carefully read the manual.
Its the best USB audio solution out there , after that you could look up all the DACs, good ones start at about $1000.00, top end up to $10,000..your choice
I have both the RME Babyface and the RME HDSPe AIO, I also like the responsiveness if Daniel Fuchs on the forum he is one of the owners and they are always updating their drivers.
I also have the Xonar Essence STX, its nice but I couldn't get the latency I was looking for, down to 32 samples
I have the HD 650 and my Stax Lambda's, the setup is 100% honest, crap in.. crap out.. gold in gold out.. in other words the top notch 24 bit Flac files come out sounding superb, junk like a Led Zepplin recording sounds exactly like it was made, pure trash. So then another issue arises, now you will start getting picky about how well something was recorded:thumb:
Good luck
