Why Don't We See More High Current Electronics?

Not sure how this thread deteriorated into a philosophical argument. Typical example of the audiophile niche market.

"High current" has faded as marketing buzz word. That's all. Still continues as a design philosophy. Don't make me name names. Doubling down, well that requires, along with adequate power supplies, a specific kind of circuit and feedback, which happens to be the new buzz word.

There's one brand, to remain nameless but with unusual sincerity, that only tests the amp into 4 ohm power resistors, and only at 1 kHz. They divide that by 2 for the rating into 8 ohms. They also claim stability into 2 ohms. It's a good brand and an impressive amp so I'm not disputing. Just saying that advertised ratings are not real-life, reactive loads.

Looking down the list for my interpretation of your electronic/price/weight criteria:

Sale pending: BAT VK500 (105 lbs), Threshold S500

Used: Belles 350A Reference

New: W4S ST-1000

Assumed you had some kind of passive. The 400 ohm Zout of the Cary should not be a concern even for an amp with 10Kohm Zin.

The 3.5 ohm minimum (4.25 - ultimateavmag) of the speakers isn't that critical either, unless it's coincides with a big phase angle, which it doesn't on those. In fact, they tend to be a little midbass heavy, peaking with the minimum impedance at about 90 Hz. Yes, they benefit from the bass control of a strong amp but, along with the titanium tweeter and some high frequency fluctuations (sibilance?), I think you're going the wrong way. Although, you could do much worse than the ones mentioned.

@Unsound... That's because I've been laid up and bored to tears after knee arthroscopy.
