Correct method of hooking up Sonus Faber speakers?

Try both ways to determine yourself......it doesn't cost anything and it can be done in seconds.

Just go with the way that sounds better. It won't hurt anything. A set of quality jumper cables would probably be a good investment. If you call The Cable Company they should have some several options. Also, a good local dealer may make some up for you. John at Audio Connection made me some really nice jumpers using Kimber when I bought my speakers.

I used to use two separate runs of Tara Labs Space and Time speaker cables without jumpers. I have switched to using the jumpers with a single run of heavy Tara Labs RSC Prime Bi-Wire cables. I don't remember reading the SF recommendation of using the upper terminals, but after reading your post I moved the banana plugs to the upper terminals. I have doubts that it will make a difference, but I'll give it a try.

At least for my SF Evolutions I connect the speaker cables to the bottom terminal using the jumpers. I believe that was recommended per the manual.

You might want to try the new Nordost Jumpers. You can order them in any configuration you want... and at $150 they're a bargain.

Thanks for the observations and advice re hooking up the Sonus Fabers. I'll try both top and bottom and judge for myself as a couple posts have suggested. Oddly enough, I'm looking to tame the top a little. Older SF models seemed to be more relaxed than the Olympicas present so far.

Just to add to the possibilities, some members here have reported in the past that best results were obtained (with various speakers, probably not SF's) by connecting the two conductors in the cable on a diagonal. That is, either the + wire to the top and the - wire to the bottom, or vice versa. (I don't think which diagonal is used would make any difference).

Doing that would result in low frequency currents and high frequency currents each having to go through one jumper during their round-trip from the amp to the speaker and back. While by connecting both conductors to either the top or the bottom one of those currents would be going through two jumpers, and the other through none.

Personally, however, I suspect that the effects of any of these alternatives on the brightness issue will be minor or negligible in comparison to speaker breakin if that may still be ongoing, or other factors such as speaker placement and toe-in, room acoustics, amplifier/speaker synergy, etc. Assuming, of course, that throughout the comparisons good contact integrity and tight connections are maintained, and that the equipment is in an equal state of warmup when the various connection arrangements are tried.

Good luck. Regards,
