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

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............

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

Would it be those audio boards (CEC Wellfloat anti-vibration platform and BDR Carbon Fiber board) take away the bass?
If they are, the impact to source or the power amp is higher?

Would it be the spike bases (strong in anti-vibration) create the problem?

 

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???

Thank for All.

The Digital AES/EBU pair are  Wireworld Platinum Starlight 7. (My mistake of always mixing up Wireworld cable names)

Not sure how to describe the bass region.
In pop music, the drums are not punchy enough. 
The big bass (like those played by Ben Wolfe) is not deep enough.

Thanks.

Tomorrow I am going to try removing wellfloat board from the source.
If the improvement is there, I am going to remove all wellfloat board and BDR carbon fiber board.

I am also going to try removing spike base or TACO board or both from the speakers to see whether it is the problem.

I hope the above could improve (regardless bog or small), or....

I have been using the Amati for a year. Previous it was Cremona, which I could not experience good bass.

The bass I need is just simple as , drum is a drum in pop music, big bass is big bass in jazz....I do not need those bass at the level which makes my heart beat jump with them. 

I have never experienced satisfaction of performance of my systems ever since, so it has been upgraded gradually of pre-amp, speakers and all cables and speakers. (Only components no change are source, DAC, and Amp.)

Until now, after putting in Platinun Startlight to Source -> DAC, Zero Gold to DAC -> Pre,  Opus MM to Pre->Amp, I am more happier than before, EXCEPT the bass.


I have been wondering whenever I visit audio shop, there normal system performs quite well in bass (and other aspects.)
No need to sit in the optimal listening position, just entering the door, I can be immediately attracted by the music. From far away, from behind the listening position, the bass (and other aspects) are very good.

Normal system, normal cables, except some good ceiling panels. Some of them even have big glass shelf next to the system! The systems are just in a corner of the space, not in a dedicated audio room, etc etc; BUT they perform well in many aspects. The importance is the music attract me right after I enter the shops...So I am still wondering what has happened to my system.


Believe me, those systems and the rooms, in audio shops I am talking about are normal (you know what I mean of "normal") compared with many of our systems in the forum.

TODAY,
I removed wellfloat anti-vibration broads from source and DAC, the bass has obvious improvement, and lost nothing from other aspects.
I removed wellfloat and carbon fiber board from Pre and Amp, additional bass improvement.
I am  happier than before of the system now.

The next, I will try taking out the spike base, or taking out the audio board, under the speakers, tomorrow.

Cannot wait.  I tried
- taking away spike base and resting speakers on TAOC board, No improvement
- removing TAOC board, placing spike base on carpet. Addtional improvement of bass.


Now, all wellfloat board, BDR carbon board, TAOC boards are removed from the system, the BASS is back! Also, more details are heard.


That means in my system, all these boards kill the frequencies.

(My wife likes music and is a concert goer, but does not know anything of hifi. She gave a comment that the system is much much better with more details and good bass.)

Why there are so many such boards in my system in first place? They were there since several generations of upgrade. I kept using them and thought they were helpful............my knowledge was/is so weak!

Thanks ALL for the advise. All suggestions/ideas helped.

The focus of the topic was to find out/address issues of the bass problem, in the current set up.  Changing gears should be considered if nothing we can do about the current set up.

As previously reported, after removing all the BDR carbon boards from source, DAC, the bass was improved a lot.
Removing such boards from Pre and power, it was further improved.
Lastly, removing TAOC boards from the speakers, additional improvement was found.

Now, the system had good bass, with more details, and I am very happy.

In brief, I might say such boards have killed the bass in my system. (Your system might be different)
