long interconnects and short speaker cables

Gosh, no one ever thought of posing this question. Thanks for what promises to be a stimulating discussion.

I beleive what 9rw is letting you know is that if you do a search on this forum you will find plenty of discussion on this topic.
Also, if you look up 9rw's past threads you will see that, gosh, he has only asked questions nobody has covered before. At least not in the last week or so before he asked.

Agaffer: Oh really? Which thread specifically are you referring to?

You'll do well if you use 600 meter I/Cs with a pre impedance source that has 6 outputs per Ohm. On speakers use 6 speaker cables per foot. Your speakers should have treble.

The other option you might consider is using 600 speakers stacked so you only take up a foot of space and 6 pre-amps, each with thier own high impedance Ohm meters so they output a treble response. In this case, cables and length are a none issue.

BTW, meantime, till you get this all figured out, why don't sit back and just enjoy some MUSIC

Cheers!

gee robert, if i followed your advice i would miss the entertainment from your humerous and enlightening posts.

your comments are more amusing than david letterman's monologues.

can i enroll in your comedy classes ? maybe i'll find a new career as an audio comic.

keep it up, i'm so amused i'll sell my stereo and read your posts.

you'll have to promise a continuous stream of gems.

maybe you can post them on your website

Good grief, Charlie Brown, no one answered Mrtennis's question.

Do this: Find out your interconnects capacitance rating in pFd per foot. This will be a number around 10 to 250 pFd or so or maybe more if you have high capacitance cables.

Multiply this number by 19.7 and then put that number for C in this formula:

fc = 1/(3768)(C) This will give you the upper frequency limit with a 600 Ohm output impedance from the cables point of view. What you have downstream or upstream of this may impact the fc substantially more.

Of course, what it sounds like below that frequency point is another issue, but I assume you like the sound or you wouldn't be asking the question. But, your sound will drop off rapidly after that fc point.

In general, you are better off moving signals into a high impedance over distance than a low impedance over distance, so longer interconnects have an advantage over longer speaker cables. This is very general, though. What you may own may change this completely.
