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!!

Thanks for all the advice.

I will check the speaker phase as the first step.

Seems my room is normal.

Seems the Source should be good?

Would it be the spike base, or Wellfloat anti-vibration platform, or even the Power Supply?

 

Here is my full system set up

Speaker: SF Amati (Spike base = Silent Mount, Audio Board = TAOC SCB-CS

| - SC = Jorma Prime

|

Amp: Esoteric A80 (Audio Board = BDR The Source carbon fiber)

| - PC = BMI Oceanic Statement (no power supply)

| - IC = Transparent Opus MM

|

Pre: Esoteric C-02 (Audio Board = CEC Wellfloat anti-vibration platform)

| - PC = Jorma Prime (Power supply = combak reimyo als-777)

| - IC = Tara Labs Zero Gold

|

DAC: Esoteric D-01 (Audio Board = CEC Wellfloat anti-vibration platform)

| - PC = Jorma Prime (Power supply = Kojo Aray MK II)

| - Digital = Wireworld Platinum Eclipse 7

|

Transport: Esoteric P-01 (Audio Board = CEC Wellfloat anti-vibration platform)

| - PC = Transparent PLMM2X (Power supply = Kojo Aray MK II)

 

All equipment/cables: 2nd hand

Audio Rack: TAOC MS MKII (Spike base = Silent Mount)

Speaker position:  away from wall = 0.5M, distance between speakers = 2M

Room size: 5M (wide) x 6M (depth), thin carpet flooring

 

Thanks............

Two other things come to mind - fluctuating voltage and power amp/ speakers mismatch.
In the daytime voltage over here drops and my rig sounds like a big boombox, and forget the bass. Later in the evening on some days and with some recordings I can get too much bass.

Checked the Polarity is OK. Nothing is strange of this part.

The power supply in my area is stable and I am using good power supply unit. Day-time and Night-time are the same in system performance.

For Power Amp/Speaker mis-match, how to find it out?

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.
