True, but with reservations. Class D requires different answers as to how to
bring out their best. Cost is less important than type. In fact, some very costly
components can do a lot of harm to the music. I have had my H2O amps for
years, and have learned a lot. If you please, here are some of my findings.
1) fully shielded power cords. Money does talk here.
2) simple interconnects. I use Speltz ICs. That way I can keep them long, and
my SCs short. I have mono amps. There may be better, but they will follow
the same principle of simpleness.
3) Naked SCs. I have found DIY ribbon SCs to be the best, and they cost so
little. Insulated SCs emit a very audible haze to the music. I interpret this to
random capacitance injection. The thicker the insulation, the more distortion,
regardless of price. Don't even think of hose through a box SCs.
4) If you are using a digital source, no over-sampler player (the vast majority)
will come close to the performance of a fine non over-sampler. The
superiority of even the cheapest NOS player over the most vaunted SACD
player will amaze. Digital filters do horrible things to music.
These same class D winners will make little to no difference to any
conventional amp usage.
