I am in the process of deciding what new converters to upgrade to. It is not quite as easy to compare such items as it is to compare, say two mics. Since it will be somewhat difficult to arrange a "shootout", I'd like to prepare beforehand as best I can.
What should I be listening for? Distortion? Noise? Transient response?
The reviews often speak of "widened stereo field", "warmer mids" and other such subjective phrases. While I'm sure that some of this comes down to taste, there must also be some objective improvements in the more expensive units.
Any advice would be appreciated.
