I'm wondering if anyone has played with bi-wiring T2+'s vs. just plain single wire and if any differences were noticeable? I'm starting to lean heavily on taking the plunge, and my current speaker manufacturer (Vandersteen) absolutely insists on bi-wiring theirs, but I'd rather not if there was little noticeable difference. My main interest at this point is clarity, and I have noticed that in comparing the Stealth-8's to the Vandy 3's (20 years young) there was definitely more inner detail on the 8's, and I am presuming/hoping the same would be true for the AMT-topped T2+'s. No lack of good power behind the curtain (Emotiva MPS-2).

Even though you do have clean power, you may experience an improvement going to the Emotiva PA-1 or XPA-1 gen 2 amps.
For bi-wiring, I say why not. I doubt you'd hear much difference. My speakers are bi-wired and I can't say I can reliably tell a difference though at times I feel that the sounds "flows" dynamically a little easier, but it could very well be imagination, that's how small it is.

My Paradigm 7's came with separate terminals for "bi'ing"; so I bi-wired them. I could hear absolutely ~NO~ difference, so when I re-wired them I did not bi-wire them, and again could hear no difference. I did use 12 guage wire, which was probably overkill. www.amazon.ca/gp/product/B003L18SFYSincerely /b |

Don't buy extra speaker cables to bi-wire, but if you have some laying around taking up space, try bi wiring out. I doubt you will hear a difference. I tried bi wiring my Revel Salon Ultra 2 speakers and I didn't care for the result, so I just put the jumper back and left the double wiring in place for what was effectively a wire gauge increase. (Caution that all speaker wires should be identical brand and length)

I've tried bi-wiring before, and have never heard a difference. Yes before I tried it, the Physics classes I had in college told me that electrically these two ways of wiring were equivalent and that I shouldn't hear a difference, thus the outcome was what I had expected. I do however think that experimenting is part of the fun in this hobby, so give it a go, listen and form your own opinion!!!  |

Bi wiring or Bi amplification OR standard one channel two wired connection....the goal should always be to deliver all necessary power to the speaker (or section of) to avoid under power issues rather than looking for sonic nirvana.
This subject has been one for decades that has been great for opening the wallet with (in most cases) no benefit whatsoever.

(Caution that all speaker wires should be identical brand and length) I agree except your last part regarding length and brand. As long as the resistance is in the ball park, neither of those make a difference. Bill |

Experimenting is definitely a good idea to see if it sounds good to you. I notice a difference when I remove the jumper pieces and replace them with a little piece of speaker wire. There is a little more openness with the tweeter when speaker cables are plugged in the bottom terminals. When plugged in the top terminals not sure if there is a difference in the bottom but it's not hurting anything so that's how I leave it . I do this on any bi-terminal speaker. Monoprice has speaker wire that has a solid core surrounded by regular strands which in the reviews people swear they hear an increase low frequency's, sounds like fun to try ! I did the same thing, but not for the same reasons. My mains have toggle switches that bridge the sections and I wanted to bypass them. (thin wired and the toggle itself). Bill |

As has been said by many before me, "bi-wire = buy more wire." If you don't mind the cost, sure, experiment and play around. You might like the looks of it. Perhaps even the sound. That's part of the joy of this hobby. But there is no scientific reason why it will make any difference whatsoever unless you are starting with grossly under-sized wire gauge.

Big Dan (who should have a LOT of experience listening to the T2s) claims that for speaker wire lengths of greater than 12' biwiring provides audible improvements. Take his opinions for what you think they're worth. I, personally, am inclined to agree, at least on this issue.

To open up another can of worms......I have 2 PA-1's just sitting unused....I was thinking of using them to power the upper end of my ERT 8.3's. I'm currently using an old XPA-2 Gen1 with the jumper installed to power them. Saturday's can be boring when you wake up and it's 7* outside, Lol

More power to you...…(or them). Bill |

I had them powering the ERT's......then went back to the XPA-2. I bought the PA-1's based on some guy's review....you might know him. Plus they were on sale and I had a few adult beverages as I recall....Hahaha. |

I'm currently running my T2s with the PA1s, and have impressed a variety of visitors with the results...

I'm currently using an old XPA-2 Gen1 with the jumper installed to power them. Saturday's can be boring when you wake up and it's 7* outside, Lol Since you opened the can of worms I'm going to go fishing. MY experience with the PA-1 would lead me to advise you to do the opposite. I would use the PA-1 to power your woofers and the XPA-2 for your mid and tweeter. Why you ask? I have been bi-amping my Chario Sovran speakers for ten years now. First using 4 amp blades in the MPS-1. Then 2 amp blades from the MPS-1 and 2 Jolida JD 502p amps specifically designed as mono blocks. I finally figured I was not using the MPS-1 wisely so it is now gone. I bought 2 PA-1 amps to power the woofers but thought lets see how this amp sounds full range to my speakers. Hated it. It made my mid and tweeter sound terrible. But it brought my woofers to life. So I'm now using the PA-1 for my woofers and the Jolida JD 502p's for my mids and tweeters and love my system's sound. I have seen several posts that praise the PA-1 amps. For ME in MY system they will only ever be used to power my woofers. Mark |
