    HALO SMOKES!!! Parasound JC1 Monoblock Lab INCREDIBLE Measurements in Stereophile

    Parasound JC1 Monblock mfg specs:
    continuous 400W into 8 ohms and 800W into 4 ohms, short-term 1200 watts into 2 ohms; 1st 25 watts in Class A (option to reduce to 10 watts).
    17.75W x 7.7H x 20D, 81 lbs, retail $3000 each.

    Most amps that spec a doubling from 8 to 4 ohms don't do it in a lab test. For example a 300/600 turns into a 400/650 lab test...yes, the mfg beat his specs, but his amps don't double in my book.

    JC1 lab results. Class A up to 29W (where most listening would occur).
    Power at clippling (about 1% THD):
    586.5W into 8 ohms
    1154W into 4 ohms
    2255W into 2 ohms
    4200W into 1 ohm

    HALO SMOKES!!!! Double-down all the way down to 1 ohm!

    Egads!!!

    I guess Parasound isn't kidding when they say they want their new Halo line to compete with the big boys. And, Parasound amps sound wonderful to boot. Someone's gonna have to have a lot of dough to buy them though.

      Sound like amps of great beginnings. Any pictures floating around?

          Yowza! Read the review last night. If it's as good as advertised, it ought to be something special.

                Actually, one comment in the review was about not leaving a full 5 or 6 of these on all the time due to the higher room temperature and electric bills! Also, I think these babies are about 80 lbs. a piece! Oh, my aching back.

                  David,

                  5 or 6 of these can replace a fireplace for the winter During the summer, you can choose the 10W setting.

                  I hope I'm not the only one in utter amazement at these lab results. I thought the only amps capable of huge output and doubling down into 2, 1 ohm were the ultra expensive Boulder monoblocks.

                    Impressive literature on the site- I'll have to pick up the review.

                    But at 80 lb apeice, they're not exactly "small"- significantly heavier than my 70 lb. Aragon Palladiums- which are 125 watts class A at 8 ohms, and clip at over 600 watts at 4 ohms and 1100 watts at 2 ohms.

                    So who's going to pop for a pair of these puppies and let us know how good they are in the real world of music? :W

                    -Jon

                      RE the amp weight. My Proceeds weigh a 100 and 120 pounds respectively in the box (HPA-2 and AMP5). Oh my goodness getting them out of the box is trick one. Then you sit it in the floor and look at it for a while. Then your ready for phase 2 of actually getting it up to get in the rack. Oh my aching back.

                          Where does the 81 lbs come from ? The spec sheet says 64 lbs, which is plenty, but a lightweight compared to Lex's babies.

                            Not at 64lbs PER CHANNEL.

                              It came from Ricky's listing of the data sheet in the first post:
                              17.75W x 7.7H x 20D, 81 lbs, retail $3000 each.
                              UPDATE: I re-checked the printed article and yes, Ricky's listing of 81 lbs. each is correct.

                                The 81 lbs came from the Stereophile review, and does contradict the spec sheet. I guess someone will just have to buy a pair, measure them on a scale, and let us know for sure

                                  That explains it! :B

                                  They probably slipped bigger transformers into the review samples which explains why they weighed 81 lb(as opposed to the spec'd weight), , and why they doubled down into low impedance loads! :roll:

                                    I guess I am going to have to order 8 of them.

                                    Well they will put my current Parasounds to shame for sure!

                                          Uh Trev, if it's not too much trouble, could I "borrow" three of your 14? I'll treat them really nicely and you'll never know they are missing!

                                            Trev's a wild man... ya know, 14 of those babies will keep your igloo warm too! 'Course, you'll have to have the power company upgrade the transformer to your house!

                                            Maybe you could pull the burner out of your furnace and mount the amps inside, so you can heat the whole house with them! 8)

                                                If its power you need check out the Innersound Kilowatt Monoblock:

                                                8 ohms: 1,000 watts
                                                4 ohms: 2,000 watts

                                                At $13,995/pair they ain't cheap, but not sure you can get a better sounding amp. Go here to see it:

                                                  I agree that the "short bursts" do not qualify as continuous. However, the JC1 did do 550W continuous into 8 ohms ,easily beating the 400W spec. Perhaps, continuous is more like: 550 into 8, 1000 into 4, 1600 into 2. Still incredible.

                                                  Doug,

                                                  I think what's amazing about the JC1s is they ARE being compared directly compared straight-up to $10,000+ per pair amps like the Innersounds.
