New Linear Parasound Halo JC1+ monoblocks, an even more improved new John Curl design

The good old linear Halo JC1’s monoblocks were released 2003 and were one of the best and could drive anything without a sweat, even the Wilson Alexia with 0.9ohm loading.
These new linear JC1+ monoblocks have some very good improvements, and even better drive ability than the old.
At $17k not exactly cheap, but probably better than any others amp around that pricing.
Enjoy.

Some serious current ability, peak output current is specified as 180amps!!!, to drive down to 2ohms without a sweat, as the distortion figures don’t change from 8 to 4 to 2ohms.
The JC 1+ is specified as being able to deliver
450W into 8 ohms (26.5dBW),
850W into 4 ohms (26.3dBW),
1300W into 2 ohms (25.1dBW), all at 0.15% distortion.

What about these. Apparently Underwood HiFi has a few monoblocks FS

Ampzilla 2000 is a 300 watt mono amp that is stable into 1 ohm loads. Reviews have been superb In the The Absolute Sound product of the year review they said: "The combo (of amps and preamp) is far from inexpensive though that figure does include two excellent phono preamps and a headphone amplifier. Reflect too, that there are competing electronics exceeding $100,000 that give you far less of everything." The entire circuit is fully balanced from input to output and includes a unique new unbalanced-to-balanced converter for single-ended inputs.
  • 8Ω: Minimum 300 watts, 20Hz-20kHz
  • 4Ω: Minimum 540 watts, 20Hz-20kHz
THD and IM Distortion: 4-16Ω less than .05% @ any power level up to rated at any frequency or combination of frequencies between 20Hz-20kHz List price $10,200.00 Sale $5,100.00/Pr in blue Ambrosia preamp
