That's the BFA for you, a type of touchproof terminal. In fairness to Cyrus, there's not much room to use anything else.
Your problem remains a bit of a mystery though.

Yeah. But just looked with a pocket lamp and after some reconnecting they seem to be clean...maybe you're right, I'll try this out. Now still there is a significant sound difference. By upper giving me fatigue after a few minutes , with lower it sounds simply right.
Ideally you want these cleaned with KONTAKT PRF and a brush. It evaporates without leaving residue. It's widely available in Germany I think.
Yes I have a kontakt spray...I thought about it too.

Vladimir said:Many ppl are staggered what improvement in clarity a new cable upgrade makes. The real upgrade sometimes actually is cleaning an oxidized connection by swapping the cables.
QuestForThe13thNote said:I think they are in parallel and the nail has been hit on the head in this thread. It’s nothing to do with which is better but it’s probably to do with oxidation of the speaker wires and cyrus pins. How long since you last removed? What cables? And predominantly which sets of plugs are used? These will all give a clue to which sound better, and a better connection can of course give a better sound!
Cyrus can be high end depending on which units you use. On my cyrus Mono x200 Signature power amps there are two sets of speaker terminals and it makes not a jot of difference to sound quality as they too are in parallel I think. I just use the top set. I have deltron plugs soldered onto chord epic reference cable.
I know it’s recommended that you use proprietary cleaners, as stated in this thread, to get a good connection. It could also be that if you’ve used the bottom ones and left the top ones the pins of the cyrus amp might be oxidised such the connection isn’t as good. It’s hard to get at them as they are enclosed in a red and black plastic sheaf, if you have the same ones as mine. The 8vs2 is an older model amp and this makes me think even more that it’s to do with this, as a newer amp means less oxidation and less issue in these regards. It could also be that your speaker cable needs restripping. Are you too using the cyrus plugs with screw connectors? Wouldn’t recommend these, get some 4mm soldered bfa plugs or deltron plugs. Hope helps.

Sadly not be because my old Cyrus only has one set of terminals. Surely they're just wired together though.
MajorFubar said:Shame that cleaning the sockets is such a faff, if that's all the problem has been. My Cyrus 2 uses good old fashioned banana sockets: easy as pie to clean with a cotton-bud and isopropyl.
stereoman said:And it seems now that the culprit has been found. I have yesterday turned the amp over to take a look inside a bit - in general crystal clean...but wait a sec, what have I found ? On both sides slight electrolyte leaking has stained both circuit board printings symetrically ! Took out my freshly bought 96% Isopropyl out and gave it a clean so almost no leakage stains are left now - and sound came back to life , came back to what it should have been like. I wonder why these good caps (made for Audio) leaked a bit...I mean no so gross nasty gunk but it seems like a tiny leakage from two caps spread evenly alongside printings, dried and left this nasty residues (brown layers) but untouched anything else in surround. Nonetheless electrolyte touched anothers two small capacitors. So Cyrus 8 users you can check this out too, just in case - if your machines are spotless clean inside or some caps are playing up a bit.
QuestForThe13thNote said:I remember the guy from cyrus yesterday talking about the fact the caps have a limited life. How old is your unit?

That would make sense - 8 up to 10 years old max. Sth like that. Does it sound like I should exchange them now ? Or simply leave as the leakage was not so huge...
