To Dac or not to Dac?

Thinking of buying a benchmark dac and either using my marantz 8260 (I think the analog out will still output sacd to a different input on my pre)or my old sony 7000 dvd for a transport,not sure what setup is better?
Anyone that has the benchmark show an overall improvement
in resolution to justify the 1k price?
Any input on my toying would be helpful.
Yes.. I love my DAC1.. I used it with my Sony 7700 & there was a noticeable improvement.. Although the Benchmark is accurate, detailed, with great clarity.. I don't find it very musical.. It has been described as cold, analytical, boring, With a bit of grain in the highs.. What sound are you looking for?
