Rich: not yet. Only the wood and metalwork to go (still). New baby will delay things a bit but at least all the peripheral jobs on the hifi done 
Harmonic: don't worry. Balance to SE the way you are doing it is unlikely to work well. The magic is in the receiver. Stick with RCA until your mods arrive.

Thanks. I will do this. I had already doubted the cables or the Neutrik EMC having an effect on sound after all.
why are you mixing Balanced Impedance with unbalanced?
If your Receiver is Balanced Impedance Input and you use a Balanced impedance cable for the connection, then you should be using a Balanced Impedance Source to feed that cable.
Look at Ap note an003 from Jensen.
section 2.4 - A simple Alternative
shows how to convert a single ended Source to Balanced Impedance. It uses three extra passive components and costs <£1 (plus the cost of the XLR socket).
And if you don't trust Jensen, then look at B.Putzeys Balanced volume control. He adopted the same topology for his Balanced Impedance Output.

My bad - The linked article explains it all. I guess I just wait for the boards to arrive and stop killing time with unnecessary mini projects. Regardless, I learned something. Again thanks for the article.

Rane Corp. is another good source for white papers written in reasonably plain English.
Re. fancy cables: 99.99999999 % (maybe with a few more nines) of cable folklore is marketing supported by the irrationalities of human cognition. The remaining bit is physics. Ohm's law is pretty well established now. I think we can regard it as fact. Same for transmission line theory. I wrote a few pages back about when and how transmission line theory applies in audio circuits.
There's a fine line between being open-minded and being gullible. I prefer claims and ideas to be supported by scientific evidence. Others are free to disagree.

There was once someone told me a certain type of RCA connector was the best he had tried. He gave me a pair, nothing exotic, the structure was the most straight forward I had seen with minimum bends in the ground path structure, core material and plating had good uniformity in copper content.
Just recently someone asked me to try out something for cars that will reduce fuels consumption. Having already tweaked my car for some 15% over the stock configuration with some acceleration improvement as well, I was skeptical. Never the less, I still agreed to give it a try expecting maybe 3~5% based on the description on how it works; surprisingly, it gave me another 12~15% saving. But it reduced acceleration capability. After studying the design, I figured out a possibly better method, currently under testing. Acceleration is even better on freeways and I am constantly passing other cars with less effort. This is an example of an open mind.
Basically, there are many things that the original manufacture will hide to protect his design efforts, but if you can make a reasonable judgement, about the possibilities and listen to what customers are saying, the possibly you can figure out a better way. I listen and ask questions when I do not quite understand reviews on my stuff, and try to sit in during review sessions whenever possible.

I know it...
Can't stay away. It was good to be without reliable internet (not to mention having to walk to an office to connect) for two weeks. Life's good. Arrived back in Cow Town a few hours ago.Congratulations!
BTW: Re. cables: I realized that my post on cables and RF parameters was in the LM3886 DR build thread: http://www.diyaudio.com/forums/chip-amps/295665-neurochrome-lm3886dr-build-13.html#post5106556

Tom, are you ready for Modulus-D? Best in class, done right, with lowest THD Class D amplifier.
I think it would be a great addition to your amps family.
It is really hard to find good quality well build Class D amp. The only one I would buy without doubts would be one from neurochrome
What do you think, Tom?
Cheers,

I'd be surprised if the Ncore doesn't currently represent the state of the art in class D ampliiers. I used a pair of Ncore 400s for my main amplifiers for a couple of years and was very happy with them. Then I made a pair of bridged Mod 86 amps. They are even better than the Ncores.
