Bass is not enough !!! Speaker problem? Speaker cable? Power Amp? PC of Power Amp?


The bass is not enough!!  Not sure which part is not good enough. Can anyone give any idea??

My system:
Speaker: Sonus Faber Amati (SC = Jorma Prime)
Power amp: Esoteric A80 mono blocks (IC = Transparent Opus MM )
Pre-amp: Esoteric C-02 (PC = Jorma Prime)

PC for Power Amp:
I had been using BMI Oceanic Statement。The sound was beautiful, but the bass was not low enough.
I changed to NBS Black Label II 。The bass was better, but still it was not good enough. However, the sound was not as good as BMI Oceanic Statement. So now I have changed back to BMI .

How I can improve the bass performance??
Amati's weak point is bass? Jorma Prime's bass is weak? 

Thanks!!

Bass is all about moving air, speaker placement and seating position.  If one of those factors are wrong, then bass suffers.  Period.

I use a separate amp and preamp to power my subs, It works great. The two systems are matched and the subs are time aligned, using a ruler, with my B&W's. I recently had to use a different preamp for a while, and my bass got really muddy, despite my amps' having once been described in a review as having "gargantuan bass".

One thing not mentioned-plug the power amp into the wall.
Corner traps from GIK or other-a must. Go for it here!
I have to have great bass also. Have moved my speakers, sometimes tenths of inches, sometimes feet. It really paid off.

Haven't measured, but suspect I get 20 hz or better, but it took some work.
Order the soundtrack for Homeboy, Eric Clapton. That will get you some bass and you can use it as a test when moving your stuff around as well as trapping the room.

Opera Lover...a lot of smoke and mirrors here.  You want dynamics, huge soundstage, low level detail and phenomenal powerful controlled bass? Do yourself a favor and try MIT.  I went through a similiar experience having spent oodles of $$$ and missing bass.  You will have impedance matched cables and sound that you could not think possible through a stereo!
