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.

Im certainly not unhappy with the EVS 1200 (which I raved about prior to getting the Voyager), but I haven’t heard my recabled system with the Voyager to hear what, if any difference the recabling makes for it as well. wows of living on SS

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

Ric is spot on (as usual). A long long time ago I had Harry Pearsons personal pair of Genesis Vs. I tried a lot of amps, but the one that grabbed them by throat and made sing was Kinergetics KBA 75- class A amp, but man the electric meter spun and even in the winter it kept my house warm. Of course that was long before class D was around, let alone top flight designs. Sadly, I blew it up while swapping out power cords, so the Gen Vs went down the road. Many many speakers later, I got a pair of Emerald Physics 3.4s which are very efficient/amp friendly, and amazing. Alas, they are no longer made as they do everything very well, however hey do come up on the used market from time to time, or the 2. series which has the same 12", but augmented with either one or two 15" woofers

For around 3 years now (or is it 4?) I have owned Rics EVS 1200, dual mono (don’t know how it compares to the Hypex 1200. After a couple months with the EVS, I got a LSA 350 GaN Voyager, which I preferred as to my ears it sounded more continuous, at least until I replaced all my WW series 8 cables. Sadly, I managed to take out a GaN module and was glad I kept the EVS1200, which sounds considerably better after I replaced the WW cabling with Ali-E mostly Odin Gold cables, which I replaced one at a time (each upgrade easily improved the sound) with the speaker cables being the last, and boy, it tied everything together. Talk about saving money!
