    Parasound Debuts Flagship Halo JC 1+ 450-Watt Monoblock Amplifier designed by John Curl

    Awesome! $17,000/pair. Quite the price jump over the original.

    The first renditions were around $6,000/pair, right?

    If they gussied up the chassis and it had some other name on the faceplate besides Parasound, these amps would be selling for north of $100k.

    I’m kind of surprised there wasn’t much, if anything, done on the esthetics side.

    They look nice, like the originals, but for that $$ and a sort of niche item, seems odd. I’m not talking luxury audio 50lbs bling case work, just something to differentiate it a bit IMHO.

    Regardless I’m sure will be a great product.

    I owned the original JC1’s and have missed them nearly every day since moving on. These are definitely going to be on my shortlist when I am ready to get back in the amp game.

    Yeah, I’m also a former JC1 owner. Just great amps, though I had reliability problems with both pairs that I had. I understand that later production runs were better built. I’m looking forward to hearing the JC1+s, maybe in my system.

    Here’s a JC5 review ... I’m sure the JC1+ will be even better.

    Joe, you and I have talked about these amps many times. John Curl is a nice man. He called me about a year ago to help him pick a digital streaming device and talk about digital products in general. He’s a close friend of Rick who works with me in the store. The JC1’s were fantastic. I would expect these are great too.

    Re: Parasound Debuts Flagship Halo JC 1+ 450-Watt Monoblock Amplifier designed by John Curl

    Good to hear that there is a follow-up for these great amplifiers. I purchased mine about 10 years ago, at a retail price of about 12kEuro/pair here in the Netherlands. I costed me serious money (and listening to many high-end brands) before finding something really better than the original JC1’s. I still own them and they now drive the bass towers from my Von Schweikert VR10-mk2 system. If these JC1s + are better than the original version, for that money they are still amplifiers to consider in that price range.

    I wonder if the JC1+ will be a step-up from my Jeff Rowland 625 S2 amplifier?

    I answered my own question. I finally listened to the JC1+ amplifiers. To my ears they have outstanding bass control, but sound soft in the midrange and highend. I heard them on a pair of Raidho TD3.2 speakers. Maybe the results would be different in another system.

    I’d be curious to hear the 625 and JC1+ side by side on more conventional speakers. I really want to hear the Rowland in my system (not the Avantgarde). It’s definitely a wonderful amp.

    Yes, they were well broken-in. In the right system they would be hard to beat. If I already owned them I wouldn't sell them to purchase a Jeff Rowland 625 S2 amplifier. I own the Jeff Rowland 625 S2 amplifier and wouldn't sell it to purchase the JC1+. There would have to be a very significant difference between them for me to change and to my ears there isn't enough of a difference to change.

    I had a second listen to the JC1+ for several hours. The bass was still outstanding, but now the soundstage was a little more open. The midrange and highs were much more to my liking. It would be easy for me to just purchase them, but I'm concerned about the size of the JC1+ and once I have them home will I regret selling my 625 S2?

    That’s a great question. Not an easy answer. I’m sure the JC1+ run hotter and there are two of them as well.

    How does the treble compare? Is it as sweet and smooth as the 625 S2?

    I still think the JC1+ is on the dark side of neutral. I think the 625 S2 is neutral, revealing what's on the recording. I think the 625 S2 treble is slightly more extended. Yesterday and earlier today I told a couple of my friends that I ordered the JC1+, but I just told the dealer to hold off. I just finished listening to my system and I just don't know why I'm even considering changing anything.
    I'm driving Monitor Audio PL500 ii speakers in a 20'x26' room and sometimes I think I need more power, but can't spend $50K to go to the next level of amplification. I'm crazy!

    I totally understand, thank you for your thoughts. I’ve made regretful changes. I bet the PL500 are wonderful.

    From your description, the JC1+ seems like my kind of amp. Ugh!

    When in doubt, don’t.

    Good advice. I will take my time and make a decision based on what's best for my situation. I won't make a decision just on sound, unless I really think one is significantly better than the other. I will take into consideration money lost on my current amplifier, the size and heat generated by each amplifier, and the fact that I would have to purchase longer XLR cables if I purchase the JC1+.

    Thoughts on how the JC1+ compare with the Pass X260.8 monos (assuming lack of power is not the issue)?
    Speakers are the Focal Maestro Utopia III. Preamp: Audio Research REF6. Dac: Holo May L2.
