Heavy Duty Binding posts for Krell KSA 250

Isn't there a Canadian forum you can inflict yourself on? What about the canuckaudiomart a? Maybe you can go there and insult people.

Binding posts with screw-down installation on bare wire can't help being inferior. Just because it will be impossible to gain intimate contact with the wire. Soldering the tips of the wire strands will help but at the microscopic level, you will invariably confirm no contact at all, just arcing to greater or lesser degrees. You can tighten them with pliers and in a week they'll be so loose you can tighten further by hand. Zero consistency in listening tests. The ultimate post is no post at all. Hence, spades and bananas should be soldered to the wire while simultaneously being crimped. I use large channel lock pliers. Now since you do have intimate contact, I would dare wager you'd never hear the difference from one post to another.

Rrog, what specific model WBT posts did you try ? Did you properly crimp WBT copper sleeves to the ends of the wires with a WBT crimping tool before attaching the assembly to the posts with the set screws ? I have done a number of binding post upgrades to WBTs and never encountered loss of bass or other negative effects.

In the case of KSA-250/150, no soldering, set screws or wiring are used. The binding posts bolt directly to output "Buss" bars within the amplifier.

Not hard at all to change for any reasonable electronics technician, but not something I'd recommend to a non electronics person. Those KSA Series amps had very little if any bleeding of the power supply caps, even when unplugged for days these amps could knock you on your butt, or worse!

Gbart, you beat me to it! proper use of the WBT binding post type for set-screw to wire, should use the WBT crimp sleeves. I've used these and they work extremely well.
