H20 Revisited

Rumadian, what are you doing for a source, and what PCs, ICs, and SCs are you using? The choices are crucial to good sound.

Muralman,

Like any other good component, the better situation you can give the Signature 100, the better it will sound.

That said, I honestly feel that this particular amplifier requires super high end sources, interconnects, speaker cable, what have you - to sound pretty darned good.

Agree with Rumadian on the Sig 100- the extended listen in my system was amazing. Only gripe would be a slight midrange coolness that can be easily tailored with a tube pre. The low level detail and dynamics are still unmatched in my system. The most musical enjoyment I have had for late night listening including my tubes. Im going to pick one up

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.
