Thank you all so very much for your expertise and experience in field. A lot of good suggestions.
I especially want to thank Verdant audio for their comments and post and taking the time to cover the topic. I really enjoy my Benchmark DAC3B and plan on keeping it and adding it to another system, in house. I believe the DAC 3B is neutral to my ears and detailed, and my R&R listening seems to meld well with it.
I guess I got SUCH an improvement when adding an outboard DAC and LA-4 pre amp to the system, I was hoping to maybe get another big jolt of improvement with a more expensive DAC???? Listening the other day to a sound demo for the weiss501 in comparison to something else. The 501 shined (wish it was just a DAC) really opened my eyes and ears, However, my wallet is another issue. Thanks Verdant! May be calling you Monday. Robert TN
