Thanks for the feedback and some explanation, I do have the same challenge that many have in that I need to drive hundreds of miles and take a day off of work to find an audio store where I can listen to some quality DAC's and even then I am quite limited. An education really helps to not be steered the wrong way by an overzealous sales person.
One other thing I saw today, Border Patrol, good reviews and nice price point (at least my price point being of modest income). They say they use a R2R DAC chip. This seems to be somewhere in the middle, is it a hybrid design?
Being an older guy with Tinnitus, I tend to listen at lower levels and anything I buy cannot have a sharp top-end as it sets off the tinnitus pretty bad and then I am out of business for a day or 2. I know the overall design is what wins the day, but in general would this fact guide me more towards a R2R or a delta-sigma DAC?
Again, thanks for taking the time to educate me.
