Can anyone offer any suggestions for optimising the slam and weightiness of my Credos? Speaker placement has been tried but to no avail.
I'm a little curious as to the internal white wool and it's real purpose ( I'm really not one for blind experimentation ). How does the Credo differ from the SBL internally? How loose should those PIPS be? I would appreciate any suggestions as to what I could do to control things a bit until I can get my new spur/earth sorted and afford to upgrade to an 82/supercap (and pay for the divorce proceedings to boot if that happens too soon I might add!). Any Credo Swamis or Gurus out there? Anyone? TIA- Regards P.- CDS2/HI+72/180/XPS in a Base Res Control Cabinet going down from left to right -and no regrets at all!. |

Pierre:
The biggest thing I found was to get the spikes set perfectly. How easy that is depends upon the type of floor you have (wood or concrete). Try messing with the spikes to get the speakers dead upright and sitting perfectly on all four. Good luck, Martin |

The guy who sold me my credo's used to work for Naim and he suggested I try unscrewing the crossover from the cabinet and letting it hang on the wires to the drivers. I think someone at Naim suggested this to me as well. I tried it but my system was so far from optimised in terms of placement, source and supports at that time that I can't say I noticed a lot of difference. It also turned out that the runs of NAC5 he sold me were too short and badly soldered. Hmm.
Things are much better now - mostly due to the excellent service provided by Audio Excellence in Bristol ( Thank you Jason ). So I'll try it again. Costs nothing. David |

Hi Pierre:
I have Credos with the external cross-overs. As suggested above, you might try unscrewing the the x-overs from the cabinets and letting them hang by their wires BUT makes sure they don't hang against the cabinet. If they do, place a piece of unsued 1" diameter heatshrink as a spacer between x-over and cabinet, - the difference in my system is obvious. Regarding the PIPs, - I placed a small ball of Blu-Tak by the side of each PIP to stabilize the upper cabinet. This led to a reasonable uncrease in bass definition. Not earth shattering but worth while. Room placement of the Credo is a perilously tortuous subject. Mine are about 4' from the back wall and 3' from each side wall (my listening room is 26' x 13'). This 'mid-room' placement tidied up the bass a whole bunch in my room. The biggest changes (not necessarily improvements) I've found with the Credos have been wrought by putting them on various stands/plinths. Some people say M*n* work well but I ended up designing my own as my floor is "difficult". I was very surprised the large differences small changes here can make to the sound of the Credo. This is an area where you need to experiment as your set-up will almost certainly be different to mine as will your taste too (probably). Best Regards, |

To Martin C -Yes my spikes are bout as well set as I can get them. They're going through hessian backed wool then duralay underlay -the green eggboxy stuff- and finally direct onto a concrete screeded floor.
To David Scott- Could you please expand a little on why "things are much better now"? ie What did you do? To Mark Dunn - I will try what you have suggested as soon as I have completed reterminating all my ends with new Naim plugs today. Have you messed with the white wool or internals at all ? Thanks for your advice Regards P. |

quite simple. I bought an LP12/Basik/Valhalla and stuck my Akito on it, swapped the Goldring 1042 for a K9/K5 stylus - which seems more musical - probably matches the arm and 32.5 better, and got the speaker wire sorted out. All for about £260. I'm still fiddling about with speaker placement and I need to sort out some supports to replace the crap and crowded shelf I made myself.
But I've got no money! Do IKEA tables really work for LP12's? The floor's concrete. Cheers David |

Hi Pierre:
Re: >To Mark Dunn - I will try what you have suggested >as soon as I have completed reterminating all my >ends with new Naim plugs today. Have you messed No. Changing the wool would most probably result in cabinet resonance and unpredictable frequency response anomalies. I'm assuming (there's that word again) that Naim got the best compromise when stuffing the cabinets. Best Regards, |

The soldering job took a lot longer than I was hoping but boy what a difference - should have done it yonks ago- I am now a self taught Naim Plug Soldering Guru and I feel really proud!!!!!! (well actually I did have a few pointers from the head of Naims test dept but that really is another story)

I recently spoke to a dealer who says they've put sealing gaskets a la SBL in the gap, with the effect of controlling the bass in certain situations. Interesting, but I didn't get more details.
I have some which I shall shortly be upgrading from btw..... |

Hi Rico,
Could we "pry" those Naim soldering tips from you ? regards, dave |

I had asked Pierre to Share the info he got - I assume that the limp-dick response confirms he won't. So much for an interchange of ideas. best I can suggest is the antex website Introduction to soldering. Good luck, and mind yer fingers. Rico - musichead |

I have no experience with your speakers, but the single thing which has increased my systems slam in recent months has been the introduction of a M*n* rack under the sources and amps, and matching bases under my speakers.

Sorry Rico and Pierre,
Rico's right Pierre...cough it up, please. regards, dave *I usually don't whine but if someone doesn't fix this software soon I will clone a pair of humans and allow nature to evolve their offspring into computor programmers and fix this problem. Bet you my clones will get the job done quicker. |

I am sworn to secrecy.
Your nearest freindly dealer should have been trained by Naim so they might be able to sort y'all out. Business IS business after all Hey Rico - careful with those adjectives old boy. A soul more sensitive might take umbrage. Message to Chris Metcalfe - Chris I've just read your post again - when you say "upgrading from" do you mean the gaskets or the SBLs themselves? Regards P.

quote: Hmmm. Just as well I didn't call you a Humber then, or use the correct adjective. You might be forgetting that a large proportion of dealers appear averse to grappling with the complexities of a hot soldering iron, let alone A5 and Naim bananna plugs... jeez, some of them even prefer to sell you crimp-on plugs as better! From this angle, any sharing of knowledge/technique which assists punters in avoiding poor system configuration would have to be seen as A Good Thing. Your avoidance of this, and the manner is which you avoided it is limp-dick. Still, I like Jon's conspiracy theory! However, Paul is particularly polite and helpful, war and friendly, and often on the road, hence this is a little unlikely. Rico - musichead |

Maybe the stress of being friendly and considerate to us all - vile and base as some of us are - is so trying that a Jekyll and Hyde character has emerged, possibly to the extent that Pierre and Paul don't even know that they are the same person?
Perhaps the next stage will be a mysterious "ripper" figure bumping off Naimies who don't use NACA5 or prefer monster yank power amps / think the earth might be round-ish or even (whisper it) own a CD12? A police spokesperson had no comment. Shotgun under the bed time ? Johannas von Ribee |
