I wrote so as I interpreted Peng's last message in a way that if my concern is not spl ( which is by the way important for me), but the sound quality, it will be better to look elsewhere among home audio brands. If my interpretation is correct, I hesitate to own an amp with huge power but without hifi grade sonic qualities. ( and I would like to mention that I found such interpretation, if correct, contradictory with Peng's previous statement regarding placebo effect and there would be no difference to be noticed in blind test among crown and quite more pricy other home audio brands). I used the term of audiophile just for people to more easily visualize such criterion that I am talking about as we often come across with such criterion in hifi/audiophile discussions, forums like this forum. For instance for me, I am basically focused on clarity, detail, ability of speakers to produce frequencies from highest to lowest within its physical/technical limits, good sepetation of instruments, true representation of instrument sounds, good staging giving the feeling that speakers does not exist. I am not favoring any home audio equipment over pa equipments unless there is a ground you may inform me about in this regard. As I mentioned, I tried various home audio brands and did not find them sufficient either from quantative perspective ( i.e. inadequate output/ driving capacity like luxman, teac, nad the latter two of which were also not satisfying in terms of sound quality by the way), nor from qualitative criterion perspective (like cary's which was loud but not sounding well.)
