Thanks Thurston, I did indeed read that, and was/am looking for more impressions, especially after the LISST's have been burning in for a bit longer...(assuming that they might continue to burn-in for in excess of an hour), though, that they did improve significantly within an hour, that suggests there may be more there...still all ears here...
I heard no difference with them myself after burning in or warming up, I think they're pretty stable.
