Hi RM
Tumatanda narin ako ng untiunti dito sa hobby na ito.
For the wires, I agree with Jojo that, electrically, the sizes are more than adequate to handle the power that the amp will deliver within the limits of your speaker. If you want to experiment on wires, from my experience, the replacement should be made on the quality and/or construction of the wire material. Just changing the size or gage is still 50/50 chance or no change at all. The objective is less resistance so that you get uncolored or undistorted signal (no more, no less). For me I do not agree in tuning your speakers from the wires, otherwise it gets very complicated. Of course, if you find that the wires are substandard or of bad quality, change it by all means. Wires should not contribute any effect or should not enhance or degrade the sound. As long as the wires are protected from EMI, RFI and other unwanted artifacts plus you have good wire material and construction.....ok ka na.
Haaaay wires pa lang ito......hehehehe. Ika nga nila, "Kaya nga hobby eh"
And siya nga pala...What's important in audio is the synergy or what they call matching of all the components from the source to the speakers including the wires and cables. One may work in one's system and may may not work in another. It really subjective because each person have different ears and different way of hearing. It may may be good sound to one but not to another. What's important is you enjoy the music and not enjoy the components ---- OR Listen to the music and not listen to the components......
I also implied I probably (or might) replace some x'over parts (see the difference). I was just stunned by how tiny the wires were, so I think I had to rewire.
