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!!

I feel it's not the room that is the most important, but how the air volume of the room and your ears are pressurized by the speakers. Speaker placement is everything. I invite you to see my website - myspeakersetup.com, read ALL the articles, then contact me for the true answer to your difficulties. You can have the best gear available, but if the speakers aren't where they BELONG, you have no chance.

I second the questions about what source(s) you are using. In particular because the rather low 10 Kohm input impedance that is specified for your preamp will definitely roll off the deep bass if driven by the many tube-based source components (and perhaps also some solid state components) which have output coupling capacitors that have been chosen with the expectation that preamps having higher input impedances will be used.

How far is the speaker from the front wall?   Moving them closer might help the bass.

Although I agree with the above posts I have to ask if your speakers are phased in correctly?
Even if the + and - are the same on both speakers they still might be out of phase. I'm not knowledgable enough to (as many others are) to explain why but I know it can happen and could be an easy fix.

yep if wired out of phase no bass there will be with any wires or sources.
