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

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.

And they sound amazing with my Apogee Duetta Signatures.

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

I have a pair of the Zillas (from Walter) in house right now. Very good amps. Apparently Bongiorno was better than Curl back in the day on amps, the reverse for preamps. They are arc welders.

That said, I am curious on the JC1+ as in JA's latest Classe review he said the + is the more tube like amplifier. I don't think the original JC1 was known to be particularly tube like. Problem is $17k for amps built in Taiwan is a struggle for me when the originals were half that.
