Best "laid-back" speaker cable & interconnects for all Naim system?


Looking for suggestions on speaker cable and interconnects that are both laid-back and warm, but have excellent low bass response, depth and punch.

Just got a used Nait 5i (with NACA5’s) and have been listening over the past week. Rest of my gear is a Naim CD3.5 and Vandersteen 2C’s.

OMG, are these NACA5’s harsh and flat or what! Anyone else experience this? I think I have all mids and nothing in the highs and lows. No don’t get me wrong, there is some bass punch, but not like my previous Creek 5350SE and 4330SE.

To balance everything out, I either need to resell the Nait and get an integrated that is more laid-back with excellent low bass response and punch (like the 4330SE... yes, I miss her) or try and find the equivalent in speaker cables and interconnects? If that is even possible?

Here are several suggestions;
I know that Vandersteen recommends biwiring their speakers, so perhaps that would provide a more even frequency response.
 I don't know what your cable budget is, but Purist Audio cables are laid back with a smooth top end.
Also, are you using any room treatments? Absorbion and diffusion are necessary to remove any standing waves and smooth out the highs.

Last item; try posting this question on the Naim owners forum...

At one time NAIT's were unstable using other brands of speaker wire. Check with NAIM first!

He is using Naim cables. On the same amp the OP has I tried: AQ, Kimber, Tara, Synergistic, Harmonic and Cardas speaker cables. Its also interesting to note that when I tried AQ Cheetah and Panther (identical cables except one is silver and the other is copper), I couldn't tell the difference. It was the only time I couldn't hear a difference between copper and silver.

I didn't think it was relevant, but since you brought comparability, a while back I went to a Naim dealer to audition some new gear, and brought some of my components and a bunch of AQ cables because I didn't know what the dealer would have, and it was a long drive. The store owner asked if he could try some of my AQ cables, and of course I said OK. It was Saturday, and after the owner played around with my cables, he said he was picking up the line first thing Monday morning.

So given all that, I doubt there will be any compatibility issues. But I also stand by my original statement in that new cables won't be enough to fix the problem. 
5i owner's manual states naim cables sound best, but you can use a wide range of cables without causing damage to the amp.
