Lsim 707 and bi-amps
I have a pair of LSim 707 as speakers for Mcintosh MA7000 integrated amp,each LSim speaker has 4 poles for bi-wire but the McIntosh seem to has not poles for bi-wire,could I use another amp to try bi-amp system for the pair of speakers.

Just replace the stock jumpers with high quality speaker cable and be happy.could I use another amp to try bi-amp system for the pair of speakers.

That paticular Mc has plenty of power. I would just use it and not worry about biamping. For the record, I am a proponent of biamping but you are going to have to spend a lot of coin to get two amps that are better than what you have. Stick with the Mc and enjoy. That's a really sweet set-up.

The LSiM already have speaker wire for a jumper.. I wouldn't bother changing that out. Soldered connections and all.Full 5 channel set of Polk Audio

No.
Thank you very much. -
Thank you very much for every comment.

Curious...
its ~ 4" of ~ 8 AWG wire....short of soldering a solid core wire to the PCB to take the terminals(metals) out of play how could this be improved?2.2 Office Setup | LG 29UB55 21:9 UltraWide | HP Probook 630 G8 | Dell Latitude | Cabasse Stream Amp 100 | Boston Acoustics VS 240 | AUDIORAX Desk Stands | Mirage Omni S8 sub1 | Mirage Omni S8 Sub2 -
A lot of people feel using jumpers made from the same type of cables you are using for SC is ideal. Seems logical in theory. I made homemade jumpers before out of bulk 12 guage wire to replace the crap stock jumpers that came on my SRS 2s. It made an improvement. I then bought some jumpers from JW Audio having ran their ICs and SCs in the past with good success. It made a very noticable improvement over the homemade jumpers and absolutely destroyed the stock jumpers. I would love to try some Analysis Plus Oval 9 jumpers, as that is what I'm currently running for SCs and I am extrememly happy with them. They are not cheap though at $200 for a pair of jumpers, which is why I haven't tried them yet.
The stock jumpers on the LSiM series speakers are way better than any of the stock jumpers I've seen on any Polk speaker in memory, but there's always room for improvement. Now that I'm running the SRS 2s bi-amped and not using the JW Audio jumpers, I'm going to try them on my 703s and see if they make a difference. -

:idea: -
A $200 set of jumpers seems absurd. If one were that serious then addressing the crossovers, internal wiring, and taking the different metals out of play would seem to be the more extreme road to go down. Point-to-point soldered connections with no plated terminals involved.
There are a lot of internal connections vs. just the external!

Which is why I use a $30 set of jumpers and not the $200 pair. It all depends on how far you want to take it. To each their own. One day I would like to try the AP jumpers when my budget allows it or I find a really good deal on them. In my experience jumpers do make a difference.
-
Just curious.
If you're going to spend $200 on jumpers, why not just get the speaker cables bi-wire and dump the jumpers outright... -
That is another option, one that I am already doing. I am currently running a biamp setup on the SRS 2s. When I'm not running a biamp setup, I run two lengths of AP Oval 9s to the SRS 2s. The amp end on one set of cable is spades, while they are bananas on the other set of cables allowing me to run two sets of cables off the same set of posts on the amps. I've read where speaker cables that are made bi-wire (one set of terminations on amp end with two sets on speaker end) don't actually make as much a difference as actually running to seperate lengths of SCs. I ran the jumpers until I got two sets of identical SCs (except for the amp end terminations). Here is a link that explains biamping and biwiring in greater detail: www.vandersteen.com/2ce_signature_ii_manual.pdf
The JW Audio jumpers did(do) a good job for me especially at $30. There are times when I still run the jumpers and single lengths of SC just for simplicity. I change up configurations and experiment with set-ups quite a bit just for curiosity's sake. The tinkerer scientist in me can't stay still! Still though knowing what the JW jumpers did, I would like to try the AP jumpers when I can find a pair on the cheap.
Having said all of that, I didn't want to mention all of this to the OP to avoid confusion. Not that I thought the OP couldn't handle it, it's just a lot of stuff to take in if just starting out (not saying the OP is just starting out, just wanted to be on the cautious side in case that is the case).
