What do you like most about the Emotiva ERC-3 compared to others and what have you compared it to.
First, I assume your questions is directed to me. Whether that is true or not, please allow me to provide an answer. In addition to its low cost and high quality (both of which are my opinion and subjective), I believe it offers better "value" than any competitor (if just redbook CD playback/transport is the objective).
Watch and listen to this:

Then, do some Internet searches and read what owners have to say. Frankly, I've had so many other players (none costing more than $2500) in my day that it doesn't interest me to discuss comparisons.
