Very good points.
@OP,
The issue of the bass you are experiencing may be due to your equipment, room treatment/ or lack of, as well as cabling, not to mention speaker placement.
Rather than chase a shadow, I suggest PM'ing Johnny Rutan (audioconnection). He knows his stuff and can save you a lot of wasted time.
Yup, he is a dealer, but he won't try to sell you something, only give great free advice.
Of course, you can also post your system here, as well, but you'll get a lot of mixed information that will probably keep you as bewildered as you are now.
My 2 cents:
Trust me, trust Johnny. Of course, you can do a search here on Audiogon to confirm.
