Exhibit A: ARC D-130 binding post. (I think the OEM was Vampire...)

I am not a gorilla tightener. I have 2 torque wrenches and a torquing screwdriver. If I see a torque spec, I follow it.

The problem with these basterd posts is the hole for bare wire. It removes way too much metal, and just who is using a bare wire termination on a power amp?

My routine was to hand tighten and with a wrench maybe an additional 1/10 max. of a turn. Now I'm looking at $60-80 for Cardas replacements, which, BTW, don't appear to have that stupid hole.

I don't know about sound quality, but I'm advising extreme caution if your speaker terminals have a bare wire hole.

"It removes way too much metal, and just who is using a bare wire termination on a power amp?"

I use 6 gauge wire (Telcoflex), with bare (tinned) end at the speakers (bananas at the amp), the terminals can accommodate them......

(After some experimentation over the years, I've found that the heavier the speaker cable, the better. Even with flea-powered amplification.)

Wow, that sucks! I remember back in the 90s, all the dealers use some type of wrench to tighten speaker cables. I used one on my Pass Aleph Os amp, and it twisted the whole thing, and snap the internal connection. Apparently, the nut behind the faceplate was not tightened enough. I was lucky because it was a easy fix by soldering the internal wire back to the contact and tighten the nut behind the faceplate. But ever since, I would just use my hand instead...
