30 foot long Balanced Cables to Balanced/RCA Adapters into Amp's Stereo RCA inputs?

thanks everyone,

I finally understood a simple XLR/rca adapter defeats the advantage of using Balanced,

so, it's balanced for 35 lf

into this conversion box, which maintains the advantage of balanced for the long run.

I had to choose between 22 awg OFC

or 16 awg Pure Copper

considering the 35 ft length, I chose 16 awg pure copper.

I read somewhere that the % of purity between Pure and OFC is very slight, the difference in conductivity hard to measure actually; whereas I would think, the difference in conductivity 16 awg to 22 awg is definitely measurable at 35 lf.

interconnects; speaker wires (16 lf 13 awg/leg); speaker wire spades are all OFC

speakers are horns/15" woofers, 16 ohms from 1958, efficiency over 100; amp has 16 ohm taps.

cayin tube amp is 45 wpc, so volume should not be an issue, noise free and modification to frequency response the culprits to listen for.

under the floor there is no machinery, I will see if/how many electrical feeds to nearby wall outlets I cross. Original to 2 wall outlets BX; 1 new 15 amp sep ckt for the amp is ROMEX I presume

% of purity between Pure and OFC is very slight

Actually if they are being honest there isn't any at all. 'Pure' is a marketing term; OFC is what there is.

Ralph:

what choice would you have made, 22 awg or 16 awg?

Big Thinker.

1st, Two units? That is not in my DNA.

2nd, the lowest current price for BDP-105 is $950, that’s the one I bought for $900. The Darbee unit (even better video?) is another $100. typically.

These things hold their price well, I missed a very good price, $700, however I suspect it’s laser had done a LOT of work, mine barely used. The lasers go bad, I just had to return a BDP-83 with a failed laser.

3rd: IF I get superior audio from 35 lt, and superior video and audio in HT, that’s an accomplishment I would have denied myself if I didn’t try. How clever/brilliant I am!! LOL.

4th. I want to try it, learn, fail? back to it’s primary audio near the amp.

Conductivity of copper is a constant. What you want is resistance per unit of length. There are tables on line for that in terms of AWG. If it even matters. Yes, 16ga has a lower resistance per unit of length than 22ga.

I would have sourced the transformer from Jensen and installed it right at the amplifier input, saving several interconnection s in the signal path.
