No one actually knows how to lculate what speaker cable they need

The SN is at the bottom of the amp, so I managed to have 2 SN. Do you need the SN on all the amps.

Thanks. The data was passed to Mr. Rodolphe at Goldmund.
I assume that they will replay tomorrow or Mon. 
Its is 6 pm now in Swiss, 7pm here in Israel.
Sorry for the delay...

My two cents on spades ending for speaker cables:

They tend to get lose after some time. A continuous maintenance of fastening the binding posts is required. Banana plugs are way better.

For those who try to implement a thick cable (4 gauge or thicker), the spades that can fit the cable are too large to fit the binding posts. You may lose on that contact between the spade and the binding post some of what you gain from a thicker cable.

For me, if an amp or speaker is not fitted for a banana plug, I'll would avoid it!

b4icu,

I'm just demonstrating how poorly you understand what you claim to be an expert on. You're over there claiming one particular spec is the end all of describing amplifier behavior and you're prescribing ridiculous solutions based on it. I just want to be sure nobody takes you seriously or considers you an expert on audio.

We will see when the first guys here will return after giving it a shot and share with us their impression. A little patient and we are there.

I've seen what happened with some friends who listened, didn't doubted me for a minute, and ended up very happy.
