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!!

Your room is close to a square pattern and that can be a problem. Are the speakers placed along the long or short wall? How far away from the walls are the speakers? How far is the listening seat from the speakers? You have excellent gear, I don’t think that is the problem. Also, are you using balanced interconnects (XLR terminations)? In some gear the + & - poles are reversed. If so, you might try using single ended (RCA) interconnects as an experiment to see if you can recover more bass and reveal if your interconnects are wired out of phase.

What are the recordings you're actually playing?
You can also try amp with larger power. My Aerial 10t go down to 20's hz with 300wpc/8ohm;500wpc/4ohm.

Opera-

While i have not auditioned the Esoteric components, I have demo'ed their spinners. You certainly have excellent speakers + associated cabling. Per haps, it is your pre&power amp combo?

Keep me posted & Happy Listening!

Second note;

Cabling is my passion and fave aspect of our wonderful hobby.

You may want to convert to an all Jorma or OPUS system!

I have always wanted to demo Jorma cables/cords.
Conversely, I have heard the OPUS system (PC & IC) several times with several different gear combos- it never disappointed. At this price point and performance grade, it should never disappoint!

The system is at the short wall.

Speakers to the wall is 0.5M
Have moved myself to different distances, and the bass is still the same; not enough.

All cables are XLR, except Pre-to-Amp is using RCA. (Do not think + & - poles are reversed. Checked.)

I played Japanese “Diamond Dust”, by Umi matsutoya (I played many CDs. The bass is not enough)

Esoteric C-02 Pre + A-80 mono power should be OK???
