loweride57: You hit the nail on DG. My digital front-end is not great, but should be okay for most recordings. I have Cary 303/200 with Burr Brown PCM1704 DAC and I also have two Audio research DACs, DAC2 and DAC3. DAC2 has Ultra Analog D20400 chip set and DAC3 has a crystal Semiconductor delta-sigma DAC with tubes.
But some of my DG recordings are ear-bleeding kind including one by Annie-Sophie Mutter "Carmen-Fantasie" with Levine conducting Weiner Phil. This is a modern recording with 4D Audio, whatever that is. If volin is not properly miked, then it can sound harsh including mass violins as well. However, Bruckner's 4th by Abbado and Wiener Phil and Mahler's #1 also by Abbado with BPO on DG sounds fantastic. I have accepted that not every recording is going to sound great. As long as I can get most of my recordings to sound good/great, I am fine. Thanks for the suggestions.
