Actually Tvad, it was Tweakmenow who roped you guys back in after you posted your room acoustics recommendations.
I'm a little surprised that Sempaul's using a Monster lc did not at least raise some eyebrows. He already has a line conditioner, but it seems that he realizes he can do better.
I lost sight in that Sempaul stated he is hoping another line conditioner would bring him greater 2-ch warmth.
Proper line conditioning can give the perception that warmth has been added and that's in 2 ways, 1. Bass can become more pronounced and well-defined and without bloat, thus balancing the overall presentation and sounding as though 'warmth' was added.
Another way is proper line conditioning will clean the noisy AC and drop the noise-floor substantially, so that even the slightest nuances become quite evident and also by eliminating what appears to be a digital-like hash or time-smear like grain in the highs inducing negative sibilance and general ear fatigue and replacing those shortcomings with extremely pristine presentation.
So perhaps in that sense proper line conditioning will add warmth also.
On the other hand, proper line conditioning will never suppress offending frequencies as some to many very popular name brands do. Rather proper line conditioning gives you the full monty and in a very pristine musical way.
-IMO
