    You are so right. I’ve got two phono preamps to connect “out” to the amp and more. I finally can put together a one brand loom of interconnects.

    Thanks Nate. I wanted to if a novice like me could turn out great sound cables that looked pretty decent.

    Gee, this cool-aid tastes good! Just ordered the parts for interconnects. Hurry up and wait now. :)

    Good on you Mark. Can't wait till you join the party. Don't worry, this ain't the Jonestown kind of cool aid. ;)

    24 AWG , IMHO, is almost useless an AWG ...way too small. I NEVER suggested that to you !! A tutorial is needed , as I previously mentioned.

    Except for my tonearm, the smallest connecting wire I use is 20 AWG, and its under two inches in length, between my amp's Vampire RCA Input jack and the grid pin of my SET amp's input tube.

    You NEED to have a certain amount of wire in the system, to gain energy TRANSFER efficiency, which people like Jeff Day, and folks in audio and on this Forum, totally overlook.

    Tutorial : Here are some very good rules of thumb, IMHO, to guide you :

    1) Amp to crossover needs to be double or triple - in parallel 12 AWG ( m22759/11 ) for each polarity . Doubled-up 12 AWG.... is 9 AWG, dudes !!

    2) Crossover to each woofer MUST be doubled - up in parallel 12 AWG ( 9 AWG ) to each polarity !!! m22759/11 12.

    3) Crossover to each tweeter can be as small as 16 AWG, and / or 14 AWG. m22759/11 16 .

    4) All lengths should be multiples or divisor's of Robert W. Fulton's Lab-derived " basic " audio length, which is 57 1/8th inches.

    5) Any old wire type won't do, in ALL my suggestions above, its m22759/11, for various good reasons, already thought out and experimented with!!

    A picture is worth a 1,000 words, or in this case, a schematic - see below.

    All these wire decisions, and component / speaker evaluations you try to make are useless if you don't get the basic amounts of wire, between components, remotely correct , which, from what I see up here, no one does !! Wide band optimized energy transfer efficiency is the key !!

    What I suggest, regarding wiring here in this post, and schematic, is basically I believe, what my friend Dennis Fraker used in 2016 at RMAF, when he got " best room and sound at the show " by Stereophile Magazine. Its what " I " use at home on my A7-800 VOTTs, and have been, for several years now.

    Have fun, I do !!

    Audionut Next Round Is On Me

    I’ll finally be putting my Duelund speaker wires to work this weekend. They will be feeding my jbl 4333a’s some solid state mcintosh power. Impressions to follow! I want to place an interconnect order but may put that on hold till I finish the altecs. (Audio ADD at its best!)

    Have my first set of interconnects made. Yeah I like them. There was a definite upgrade in SQ. Good stuff!

    going to make mine soonish. did you leave the signal and drain wires straight or weave them together? i think jeff did the latter but can't remember. did you try shielding and/or tech flex?

    opa1 Moderator Staff Member

    I left them straight. Also used the flex cover. They look just like @MikeT. cables.

  16. Resurrecting this thread. I am considering ordering two pair of Duelund interconnects (I have no DIY skills). Are the Duelund RCA plugs worth the extra money over the Switchcraft RCA plugs? Thanks!

    I’m my opinion...no.

    Btw, Welcome to the Haven!

    I like the Switchcraft too. :)
  19. Thank you everyone. This is very helpful information. I'm going to try two pair in my system.
