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!
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

I can't necessarily agree with Thesoundhouse claiming your 501's are speaker dependent. I have a pair and have owned Thiel 3.6 and Eggleston Andra II's and the bass has been plentiful and balanced. I have heard them in Brick and Mortar salons with other speakers also. Be careful and check that out yourself.

Good advice above though, spend time with speaker placement, wall reinforcement, and finding bass nodes.

I owned the Focus 140 a while back, and it has a slightly "punchy" elevated upper bass that makes it sound like it goes deeper than it does. Assuming that your KEFs are placed well, you might be hearing bass from them that's actually deeper but more linear--and it might sound leaner than the 140s for that fact. Also, why not try swapping the + and - on one woofer just to see if the bass gets better or worse. That would answer the question about the internal wiring being off.
