Best DAC

Hey Audiogon,

This is my first post here.  I've been doing quite a bit of research and am looking for a DAC for my system.

My laptop will be the source.  I already have an Audio Research pre-amp that I find to be the best for my listening preferences.  So, I really don't need the DAC to do anything besides convert... no pre-amp or headphone amp needed.

I would like the most neutral DAC possible, and am tempted to check out the Benchmark DAC1 USB or DAC2.  I also like the Bel Canto DAC2 for its simplicity.  I will probably be looking on the used market at anything under $1000.  Of course, the greater the value, the better.

Overall, I am looking for the most neutral DAC possible because I believe that my pre-amp, amp and speakers should be the components coloring the music.  I see people mentioning that the benchmarks are too "harsh" or "revealing" but I think that may be cleared up by the pre-amp.  We won't know until its in the system, but I want to make an educated purchase.

Any input is greatly appreciated.  Thank you
