"High Current"

I listen with my ears, and I dont really often care about the mathmatical conclusions but I have a friend who argued with me that Current cannot increase without wattage increasing as a result. I understand the simple formula is Voltage x Current = Wattage or something to that effect, it's been awhile since I openned a book.

How then can an amplifier from say a company like SimAudio which has a nortriously high current intergrated in the i-5 be only rated at 70 watts per channel?

Is it the differences which the current, voltage and wattage measured that makes the overall impact or can you really have an Ultra High current amp at a very modest Wattage output?

Gregm,

The Krell Class A "Full Power Balanced" cx-series "double-down"
all the way to 2 ohms.

Take the "baby" of that line-the FPB-300cx: 300 wpc at 8 ohms,
600 wpc at 4 ohms, and 1200 wpc at 2 ohms. See:

Sean,

I really have to disagree with your remarks on the Krell
FPB-300cx. [ Are you sure you are familiar with the "cx"
variant?]

I have access to some pretty sophisticated test equipment -
with pico-second resolution - and the Krell 300cx matches
its factory specs - even with heafty reactive loads.
