Be consistent with brand?

I do not have the same cables either brand or model. To keep it short, I find all components react to cables differently. I have the best cable (which is the most important in my opinion) on the Preamp Power Amp link. This interconnect affects the sound of the whole system. The other cables are chosen around this. The same goes with the speaker cables. IMHO, different speakers sound better with different cables, so I see no reason to stick to the same brand.

For more details. I have a Nordost SPM as my Pre-Power link. Siltech to the CD Player and Tuner. Van Den Hul to the Turntable. Music & Sound Black to Tape Deck. MIT T2 BiWire Speaker Cable. A smaller system in the Den has Cambridge Audio Studio Reference to Tuner, Music and Sound Grey to DAC. LAT Digital Cable to CD/Transport. Store Brand Bi-Wire Speaker cables. DVD Player also has Cambridge Audio Studio Reference. Subwoofer has Tributaries to low pass connection. A couple Vansevers Power Cords.

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.

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.
