New Linear Parasound Halo JC1+ monoblocks, an even more improved new John Curl design
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. |
Hypex NC1200 amp module does 1200 watts into 2 ohmsPlease please! show "independent" testing of the rms wattage’s for 8ohm, 4ohm, and 2ohm loading, that will show, instead of this smoke screen you’ve thrown up. Here are just from 8ohm to 4ohm hardly doubling Then for something else, there’s the phase shift down into the audio band. https://ibb.co/Wp8qnKp |
vmk The ML 33H’s were a good wattage doubler, and should drive even the Wilson Alexia’s 0.9ohm without stress being able to do: 300w-8ohms 500w-40hms 900w-2ohms I think it would have more come down to the character sound of the amp you liked. Do you listen to the Halo JC1’s in "high bias mode"??? As they definitely sound their best to me in that, as in low bias to me they sound a touch dry, but then you feed them with a tube pre. All the big early ML’s I’ve heard and worked on, have a dark’ish sound and a little soft in put you through the wall dynamics. Save for one, the mighty ML2 monoblocks, but they are only 25w Class-A total. But 50w-4ohms 100w-2ohms 400w-1ohm still able to drive the Alexia’s to a certain volume effortlessly. Cheers George |
Not knowing this amp because of lack test measurements, the best thing I think Bongiorno did was the old Sumo Nine and later Nine-Plus ss circlotron type Class-A amps.(needed the input opamp changed to something better, also the output transistors all 20 of them if you wanted to go all out) https://6moons.com/audioreviews/thorens/sumo.gif No independent testing done on The Ampzilla 2000, yes the manufacturer gives the 8ohm-300w and 4ohm-540w, but no 2ohm figures. I've said this before a few times now, it's fine to say an amp is "stable" into 2ohms, it does not mean it can "drive" it, just means it won't oscillate and blow up. But so is a little 1980's Nad 3020 30w integrated stable into 2ohms, but that doesn't mean it can "drive" 2ohms. This is what counts, for "driving" 2ohms. (almost doubling wattage) Independent test on 8 4 and 2ohms from the original Parasound Halo JC1 Stereophile. all at 0.15% 450W into 8 ohms 850W into 4 ohms 1300W into 2 ohms Halo JC1 is a current powerhouse 1khz dynamic tone bursts, it can do 586.5W - 8ohm 1154W - 4 ohms 2255W - 2 ohms!! and no less than 4200W into 1 ohm!!!!!!!!!!! This is what you call able to "drive" 2ohms and be stable! Cheers George |
even Alexia 2 that seem to be your often touted punish load speaker don’t need anything near 180amperes of power, even for peaks. 0.9ohms epdr is almost a dead short, there is no "don’t need anything like" that’s why they sound sooo good into the Alexia’s compared to limp d**k class-d, mosfet or tubes into them. Yes better was the Gryphon Antillion with even more current, by a small margin, but way too expensive. We’ve done the a/b on the Alexia’s I do not like or appreciate the understated brushed metal chassis that Parasound is known for. Every "glitz queen" has his own idea of what’s beautiful, I like the industrial way they look without handles, but that’s not the reason for their sound. Nor do I feel comfortable paying for anything assembled in the far east for these prices.Each to his own, my new Volvo T5 is also, and a joy to drive and goes and handles like it’s on rails. And if the JC1+'s were built in the US they'd be double the $$ Cheers George |
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 Cheers George |
