Dear Dan: The Andrew Dunlavy Audio Labs SC-IVa speakers are almost full range and only a subwoofer system could beat it in the bass regard.
The differences in the quality sound perception ( everything else the same ) between a full range system and one like the Doug one is huge ( I'm not saying that the Dou system was not a good one, I'm sure it is. ) not only in the low bass reproduction but all over the frequency range including sounstage. That last one or one and a half music octave makes a huge difference and those differences are for the better. When you hear it you can't live with out it and ( like Andrew ) when you have it you can discern better on the music and this fact has a very simple reason: who could have better music perception: one person that the only music that he heard is " live music " or a person that the only music that he heard is through an audio system?, now: who could have better music perception ( all things the same ), one person that heard always music through a full range system than other person that heard always through a non full range system?
Doug knows that one of my old " feelings " ( good feelings ) about his system always was and still is the limited bass frequency range response that had his 803's, but today I know that he can't do almost nothing about because its place space limitations.
About the 47K it is difficult for sure to know where is the problem but at least in the Andrew CAT ( btw, in my Essential 3150 I never had that kind of problem ) the problem does not exist and that's why I " feel " that the problem is in the Doug unit and yes Dan we usually hear a brightness at 47K but I think that was not the problem from what Doug and Andrew posted. What is sure is that the Andrew O is incompatible with the Doug unit at 47K .
Regards and enjoy the music.
Raul.
