Re-wire of speakers to get more Warmth and resolve across the band

Thanks for the suggestions guys, I will call Eric at Tekton to get his input too.

I would leave internal wiring alone... Tekton know what they are doing and would never skip investing on the wire if it made a difference.  Just like all reputable speaker manufacturers.

If you want more warmth maybe think about going using a tube product somewhere in the system. If you can't do the power, get a tube preamp. Tubes make less of the higher ordered harmonics that contribute to brightness and so even though they may not have any less bandwidth, they tend to sound more relaxed.

Tubes are often known for a phenomena of 'warmth' which has to do with a bit of 2nd ordered harmonic distortion. Not all tube products do this- usually it occurs when the amp or preamp employs single-ended circuitry with little or no negative feedback.

Our ears perceive the 2nd order as warmth, as a musical quality. OTOH, our ears perceive the higher ordered harmonics (even in trace amounts) as harshness and brightness.

I do have a Norh 9.0. I  rewired them with siltech the improvement is huge....
