Be consistent with brand?

I will read equipment brochures and some will say they use Cardas, Straightwire, or whatever brand throughout their internal wiring. Therefore, put simply, unless you have taken apart and rewired every component in your system with your wire of choice, you are not being entirely consistant with brand along the signal path.

I had Transparent re-wire all of my stuff. It was really expensive but well worth the effort and cost. I am thinking of upgrading to internal "opus" line next. Should be around 15k per component.

Sugarbrie, I have done essentially what you describe. My phono, preamp, speakers and amplifiers do contain the same wire I choose for speaker cable and interconnect. There are hundreds of feet of wire in every stereo system that remains unaccessible to the end user. Examples are chokes, transformers, wire wound resistors, discrete volume controls, coils, printed circuit boards and other wire based products. Once the input and output wires have been replaced, and the wire in the speakers, along with the cables we are discussing, it is about as far as it can go to being entirely consistent with brand.
That being said, I am totally pleased with the results of a single "wire product" system.

NoMoney and Albertporter. I've heard of people upgrading cheap internal wires; you guys take it to a new height. I am very impressed.

If I went with all one wire. Because of budget I would probably go with Siltech ST-18G3. I would probably still keep the Nordost SPM as the Preamp Poweramp link. I bought the SPM used at less than 50% list. Could not afford a whole system of SPM, but is a keeper because it is better than any other cable I have.
