Parasound Halo JC3+ Incoming

Straight out of the box it sounds excellent. Significantly more detail (inner?) then the previous preamp. Full, tight and controlled bass, more so than its predecessor. Excellent cohesion. I would not say it is a "huge" improvement over the iPhono though, more an evolution. Big compliment for the $499 iPhono then? Or I need to give the JC3+ a lot more time?

I do have a question: My MIMC Star's "Resistive Minimum Load" stated on the bottom of its box is 470 Ω. The JC3+ has two options for MC carts: Fixed 47k Ω or Variable 50-550 Ω. The JC3+ manual says "Fixed 47k is the load that Grado and SoundSmith recommend for their Moving Iron cartridges." Does 470 Ω = 47k Ω?

Update: Cymbals and acoustic guitars on Rumors sound amazing, best I've ever heard it. The biggest improvement I'm hearing so far is in detail. A lot more detail.

No, 47k ohm ≠ 470 ohm. I'd start by adjusting the variable load to 550 ohms and listening to it there for a while. I suspect it should sound fine there and it's close enough to 470 ohms that you may not need to keep fiddling to achieve that last nth degree of sonic performance. (But you will anyway, of course! :mrgreen: )

Changed the resistance to 550 ohm and have been playing for a few hours now. This thing sounds incredible. All I can say is that the music sounds more like real music than I've ever heard. Beautiful long decays on held electric guitar notes and cymbal crashes. Incredibly full and tight bass. Incredible detail. The music is liquid and flowing.

Glad to hear that you are happy with the new premap! What made you decide on the jc3+ vs a chinook , lehman decade, or even the liberrty phono premap?

Great question, as I considered all of those. In the end it was Stereophile's Recommended Components Class A rating and Michael Fremer's review, in particular this sentence from the penultimate paragraph: "In real world priced systems it’s likely to max-out vinyl performance and keep you locked in to listening for years to come."

I'd love to do a side by side comparison to my graham slee accession but I live in the audio desert of NE Ohio where I can't find a dealer close by to audition. I'm sure the Jc is better but how much better is the question

It is no surprise at all that the JC3 is a superb preamp. For you younger cats out there, you may not realize it but the designer of the JC3 (John Curl) designed one of the most Iconic lines of phono preamps the world has never heard, the legendary Vendetta Research line...Still to this day among the finest and quietest head amps and phono stages ever made...I am using an SCP-1 in my system..No words..It still just smokes everything else I have tried..It is utterly silent while handling a .18mv output MC....It excels at all of the attributes we want in the amplification chain...Congrats on your purchase! :D

Thanks and yes I had read about John Curl's background and that was a contributing factor to my decision too.

As to trialing the JC3+, Audio Advisor (where I bought mine) does have a 30-day return policy. You just have to pay return shipping. Given that they pay shipping to you, this may be a good option.
