    Now that the order has been placed, we'll likely have a ton of questions on construction. And I have a few of my own.

    On my den and beach rigs, I have been using MIT Shotgun3 speaker cables and Canare 4s11 Dreadnought cables, Neutrik Speakon at both ends. Recently, I bought some used MIT Terminator 4 cables, thinking they might be a better match on the Dreadnought with the S3's for speakers. My questions:
    • How likely is it that the Terminator 4's will be an improvement over Canare 4s11?
    • Should I leave the network boxes in place?
    • If yes, should they go on the DN side?
    • Are there any particular challenges converting from spades/bananas to Speakon connectors?
    Thanks for any help,
    Craig

    Aren't Terminator 4's unidirectional?

    I used the speakons with the faston terminals so I had the capability of soldering on the female ends.

    ^^^^I just went through the chore of using MIT T4's for my dreadnaught speakon interconnects. To me it was worth the hassle and it was indeed quite the chore as my T4's are bi-wires. The MIT wires are a struggle to work with and you'll need time, patience and a soldering iron to tip the ends. You'll have remove the spades or banana's and you'll just be using the MIT wire. At the advice of f1nut I didn't use the network boxes. I believe this was an upgrade over the Sonic Impact wire I was using. Was it night and day? No it wasn't but it was an upgrade and every bit helps imo. As far as the T4's being an upgrade over the Canares I can vouch for that being an upgrade as well. I upgraded from Canare speaker wire to the T4's quite a while back and that is how I started down the road to an all MIT path. I went from the terminator series to the shotgun series and this is why I had an extra set of T4's waiting to be used for something. The dreadnaught itself is where the big sound upgrade is though. That one is impossible to overlook and will transform your rig.

    @vcwatkins, @F1nut
    Craig, hope you don't mind me jumping in on your questions...I have similar questions for my 1.2tl's. I'm using MIT Shotgun S1 bi-wire on my speakers and EXP1's as the IC for my current dreadnought (purchased during the B-Stock sale several years ago). Going to setup the new dreadnought with Neutrik connections vs. the Cardas binding posts in use on the 2 I have.

    Jesse, I think I remember you worked w/MIT to build your own IC from bulk cable, so, in addition to Craig's questions...
    • The MIT's are directional...which direction for the wire from the dreadnought to the IC connection on the speaker? (amp to speaker vs. speaker to amp, printed on the cable)
    • Thoughts on potential benefit of doubling up 2 EXP pairs on each run?
    • Should I eliminate the "secret sauce" box on the cable and run straight wire?
    • Thoughts on Canare vs. MIT wire?
    • Or....should I source new wire from MIT of = caliber to the Shotgun S1's, perhaps the EXP's are the same?
    Current system is PS Audio:
    1. BHK Signature Preamp
    2. BHK 250 power amp
    3. Directstream DAC
    IC's are all MIT balanced S3.3's. Additionally, I'd like to redo the 1.2's internal wiring harnesses at some point.

    Appreciate any insight you guys might have.

    John

    Thanks guys! I was able to find a thread where F1 was selling Terminator cable for Dreadnought use to confirm what you've said above.
    F1nut wrote: »
    I have a quantity of MIT bi-wire speaker cable available for making custom AI-1/Dreadnaught cables. This is labeled MIT Terminator 2 Bi-Wire and comes with a light gray Techflex type braided sleeve outer cover. This is bulk cable, there are no network boxes (can't be used with the AI-1/Dreadnaught anyway) and is not terminated allowing you to choose your preferred method. The wire and the wiring configuration are exactly the same as the Shotgun cables, which in bulk from MIT is $50.00 a foot. This will be considerably less.
    So it sounds like the Terminator 4 might be a very good match for the Shotgun3 and the boxes definitely come off, as you guys advised above. My wire looks to be the same biwire (purchased here)

    I'll give it a spin in the next week or so and will TRY to be patient, hehe. One of my cases is binding post, so I may terminate just one end with Neutrik for the speakers and keep the amp end bananas for the binding post Dreadnought.

    Thanks a million for the swell advice!

    ^^^^^Your intended pair is the same model I used vcwatkins. One thing I forgot to mention is you're going to need to hog the hole out on the Neutrik as the bi-wired T4's are a bit too large. I very carefully used a step drill and went up 3 notches. This was more than I wanted to do but 2 steps wasn't quite enough. Good luck to you

    @pitdogg2. Right now I'm only using aq type 4 and wireworld jumpers. I am down for anything! I will change speaker cables eventually.

    Gotcha, thanks. I thought it looked like it would be a difficult fit. Ordering a couple extra Neutriks, hehe.

    Wow, how cool is this! I've been tuned out for a bit, buried in construction at the house I bought a year ago. Glad to see another group buy going strong! And glad I'm not running it!!! The last one I did went off the rails.....

    Though, sadly there is apparently a current issue with a long term member here that was also somewhat involved in that discussion. But on the positive side that member has a strong support group of 'Polkies' here on the forum. I'm not involved in it but am always glad to see 'common sense' solidarity among the many members here.

    It’s good to see y’all. The past year has been a wild ride. We bought the house and then decided to re-do the entire thing! So 3 bathrooms, a kitchen, 4 bedrooms, a living room and dining room later, I’m here to say hi! Haven’t been very focused on audio with all that’s been going on. But the interior work is just about done, now is the fun part - the pool and the landscaping!

    Just for kicks I went back through that mess of a group buy thread. It gets interesting again on page 12 when he pipes back in. I forgot about the whole part where he called AL directly and tried to muscle his way into the group but through back channels. And then he accused me of only being in it for the air miles. All $52 worth. And that led me to a Githens donation as a result. Definitely an entertaining read!

    I miss George Grand. In fact, that’s worthy of a new thread....

    Good to see you Neil. Yeah, that was head-shaking stuff handled superbly by you. The guy's immodest self-destruction is pretty hilarious in retrospect (also illustrates the shift in admin since that time IMO).

    I hope you'll return often. You are responsible for several positive steps in my audio journey.

    Wow Neil I had forgotten how much of a jerk that guy was and yes indeed you did handle it superbly. Thanks to that group purchase that you handled so well for us I've been able to use and enjoy monoblocks on my 1.2s ever since. It's been a few years since that group buy but my ears still thank you.
