Before you buy another transport, you might try using the monarchy DIP - you can buy it with a money back guarantee from audio advisor or pick up used ones here for about $125. It made a big difference in my digital front (marantz cd63 and theta processor)
Transport Help
Now I've done it. I went and picked a used Aragon D2A which has imporved the sound but now I'm told my Rotel 970 is not the best as a transport. So now I'm looking for a good used transport for around $500. Any recommendations? Is there a difference in newer technology? Should a guy strech the budget to get something that much better? Any help is appreciated.
