Hi D,

I never finished the Teflon tape on the twin or single 26ga runs. Time constraints and loss of patience in those days.

Imbalance #1:
Short run to one speaker vs the other. I was able to reduce this to just under .5 db. by using two 26ga runs

Imbalance #2:
In bi-amping, I find that the Magwire (1 or 2 strand) is picky about mixing with other wires. If I wanted more punch in the lower panels, I would use other thicker cables for these (but keep the tweeters with 26ga only). I was never totally happy doing this. There were both objective and subjective observations to this effect. Net result; I returned to "all panels at thin Magwire" when the music mix did not call for extreme dynamics to be enjoyable. Remebember how I kept breaking them? That was the switching.

One of the things that the MultiMags did (when using the same type of bundle for the high and low panels) is bring a more cohesive presentation.

It all became clearer during the Razoring tweak tests with the P-Frames (and now Stick Braces). The Razoring tweaks do a great job of holding detail and texture in the mids. It made clear that even mixing the old plain 26ga for the tweeter with MultiMag842T for the lows was not the best. Luckily, MM842T for both panels does the job. It does not take away from what 26ga alone did for the tweeter before.

I may have not mentioned this: when the A21 was here for the Razoring Tweaks, I ran it with various cable sets. When I heard it with MM842T I was blown away by the sound in all respects.

Monstrous solidity of the 3D landscape was one of them.

Then, at one point, I bi-amped with the A21 doing just the tweeters and staying at volumes that kept it within class A. Oh boy!
