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.

No smoke screen....just the published numbers. I mean, who cares if it only does 1100 watts into 2 ohms at 1% distortion? Still plenty of power for 95% plus of the high end speakers. The only thing that matters is how it sounds and will it drive a particular speaker to the levels you want.

Your audio phase shift measurement for the IceEdge module means nothing (already pointed out time and time again) and it is not even for this particular amp module. You are confused. This is the Hypex NC 1200 module....not the IceEdge 1200AS1/2 module that I am referring to. What you quoted above was for the IceEdge module.

Please people, listen for yourself!.....do not trust anyone’s opinion about anything....including mine.

By the way, I measured 1000 watts into 2 ohms with the mono IceEdge 1200AS1 module (The mono modules are the ones I used in my amps). The stereo module (1200AS2) puts out less power into low impedances as there is just one power supply for both channels.
BTW, You can buy mono block amps using these same NC1200 modules, same Hypex 1200 watt supply and Weiss op amps from VTV for $3000 the pair ($2600 with best Sparko Labs input op amp). Not as good of output wiring and output connections, nor chassis nor linear power supply for op amps. Still, a wonderful value. These modules are the same as what Mola Mola uses in their $17K mono blocks. The Mola Mola uses Bruno Putzeys discrete input stage while the VTV and Apollon use the Weiss discrete input stage.

If you want the stock op amp buffer built into the NC1200.....then a pair is $1800.....Dang! Even with the stock op amp it sounds really good. The Atsah amps sold 6 years ago for $9K using the stock input buffer.

Doesn’t matter what is said here above about Class-D by some that have vested interests in them.
There is no way in the world it can compete against these Parasound Halo JC1 or the JC1+ when driving speakers such as the Wilson Alexia many of the higher end B&W’s, fact!

If you have speakers like that then it makes sense that you MIGHT have to spend tons of money on big monster amps.  There are incredible sounding speakers that don't need 83 lb. back breakers and bank breakers to power them.  Most of us audiophiles (95%) don't have speakers that require that kind of current or super low impedance drive.....super fact!  If you own speakers that need tons of current and are super super hard to drive then you limit yourself to buying some seriously expensive heavy amps to power them.  Think before you buy your next pair of speakers.  If you can get a pair of speakers just as transparent for the same money (or less) and they are much easier to drive....then you have way more choices of amps and you don't need to spend as much money.....fact.

Check out Spatial X3 speakers.....powered 15 inch woofer and 97db sensitive, 8 ohm and you are only driving 100hz on up.  Very transparent!

Check out Tekton Moab, Encore and Ulfberht......high 90s sensitivity and 4 ohms.  Super transparent!....14 tweeters in parallel acting as midranges down to 400hz.

Check out GR Research....many open baffle kits using planar, cones, open baffle servo woofers..incredible sound.....way easy to drive.

Check out Li Speakers.....Chinese full range drivers that are 90 plus db to drive, super inexpensive and very transparent. 

I am sure the Parasound amps are very very nice.  But, do you need them?  Do you really need 180 amps peak!  Are you going on tour with the Who?  Are you filling a stadium with sound?  Are your speakers really that demanding?  Do you play that loud?  Remember, a speaker rated at 90db needs one watt at one meter....maybe 5 at your listening position.....so 100db at your seat requires 50 watts....and 110db requires 500 watts (all assuming nothing less than 3 ohms).  How loud do you listen?  However, if your speaker is 2 ohm or less then you need way more power for any given level.  Super low impedance speakers just don't make sense (unless you already own them and cannot let them go)  FACT! 

The NC1200 has tons of power and there are very very few speakers that they could not play super loud.  If you have never heard this module drive low impedance speakers than you know nothing of their capability (1200 watts at 2 ohms is plenty!).  This is not an "I think" game.  This is an "I know" game.  The only way you know anything in audio is to listen.  Words are just words.  Truth is discerned by the ear.


If you have speakers like that then it makes sense that you MIGHT have to spend tons of money on big monster amps.


Glad you’ve seen the light.
No one should make out class-d’s can drive 3ohm and below, with -phase angle like the Alexia’s, B&W’s etc Like they can be driven by Parasound’s, Gryphon’s etc. And like many other linear amps known for current ability can.
And there are many speakers just like that.
