"Also, consider moving your amp next to your speaker and using long interconnects to your preamp. A better sounding alternative."
I've never understood this advice. So, sending a line level voltage (typically a volt or two at most) for 20 feet is going to sound better than sending a speaker level voltage (at least 10, if not 50 volts depending on volume) the same distance? It would seem the smaller the voltage, the more delicate and thus more difficult to propagate over distance.
I've never bought it, despite being common audiophile 'wisdom'. Explain.
