Kef 205/2

Good Morning All!

My setup consists of:

Kef 205/2
Mcintosh MC501's
Audio Research Ref 3
Fully Mod Primare CD31
PS Audio PPP (CD, Pre)
Shunyata Hydra 2 (Amps)
Nordost Quattro Fill CD to Pre
Nordost Red Dawn Pre to Amps
Nordost Red Dawn Bi-Wired Speaker cables
Analysis Plus Oval 9 Power Cords

My current issue with the above setup is that the Kef 205/2 produces very little bass comparing to my smaller system (in the same room with the same speakers positioning , etc) which consists of Dynaudio Focus 140 bookshelf, Cambridge Audio 740c and Meixing integrated tube amp (75w/ channel)! Due to the lack of bass, my main system seems to be brighter. I’ve tried to play the Kef on my smaller setup but the amp seems not to be to drive them.

Has anyone experience with the Kef205/2 or similar setup?
Can you please let me know how to improve the bass response?
I’ve tried with cables e.g. Chord Anthem, Cardas Golden Cross with mix result and ended with Nordost due to their high resolution. I do believe make differences but not substantially

Thanking you in advance for your advices

Thank You all for your responses
I don't think i have polarities issue as the speakers do produce bass but very little for the speakers size!
I'm thinking going down the path of lossing the Kef or having them mod. Do you have any comment in modding speakers?

Thank you all!
Do you mean phase is the + and - polarities?
I've checked the speaker wiring + and -
I've connected them to the correct polarities
However, i can't see connection inside the speakers
I'm so close to loosing the Kef now! I know i can add a sub but don't prefer as i've done that and there is no way it can blend in like how the woofer drivers blend in with the mid and high drivers

Don't get me wrong in saying no bass! There is bass but very little comparing to the Dyn Focus 140 bookshelf!
Bass is present with bass instrument but bass almosts non exist with string instruments

I purchase the Kef as demo. They're about 2 years old

Thank you all
I'll give it a go through upgrading cables. I have in mind the following
Acoustic Zen double barrels speaker cables
Acoustic Zen silver Ref ICs
Or
Purist Elementra
Or
Maybe Transparent

Anyone experience owith Grovers cables?

Pkoh70, with all plugs remove. Will it also reduce bass response? I tried with high freq plugs removed but ended up with replug due to loosing resolution!
What cables are you using on 207/2?
Thanks

I've recently had 2 dedicated circuits installed as the last cheaper option before swapping out cables!
Wow! I'm shock, the low and real extended bass are there now.
I re-did A/B test with the Dynaudio Focus 140. The Kefs are better this time, the bass is real extend and deep.
I couldn't believe how 2 dedicated circuits have made such a big difference!
However, I now wonder what more can do to take my system further:-).
I'm very tempting to replace:
1. The Bi-Wired Red Dawn SC's with the latest Grover Bi-Wired SC's
2. The Red Dawn IC's with Quattro Fil to make all IC's to be Quattro Fil
3. PS Audio PPP for CD, Pre with Shunyata Hydra 6 to make all conditioners to be Shunyata. May also swap power cords to Shunyata Python for amps, cd and 20amp Anaconda for pre. IMHO, Shunyata is better than PS Audio in conditioners and cables

Oh dear... the cost will be high. This is a very expensive hobby! But again...

Edorr,
I run Hydra 2 for my mono blocks and I feel Shunyata doesn't limit the flow of music, etc. I'll look into PS Power Cords for the ARC Ref 3 and Primare CD31 as they are connecting to the PS Audio PPP.
I think the same brand conditioner and cables may work better

Has anyone listen to Grover cables? Grover allows in home trial so i've given a go and placed the order for a 6 ft pair bi-wired SC's. According to Grover, the high and mid cables will have a mix of silver, copper and titan wires. The low section will have copper wires
