PARASOUND JC 1+
JC 1+ er Parasound sin nye høyeffektive mono effektforsterker. Det å lage en forsterker som er i stand til å fremkalle den aller beste ytelsen fra de fineste høyttalerne, og samtidig overgå konkurentene med langt høyere pris, gjør JC 1+ til Parasounds mest ambisiøse product til nå. Parasound rekrutterte nok en gang et design team ledet av den legendariske lyddesigneren, John Curl. Mannen med initialene «JC» star bak selskapets kritikerroste og kjente JC 1, JC 2BP, JC 3+, JC 3 Jr.
Med en kraftleveranse på 450 watt RMS til 8 ohm, 850 watt RMS til 4 ohm, og 1.300 watt RMS ned til 2 ohm – sammen med en topp strømkapasitet på 180 ampere, fremkaller JC 1+ fantastisk ytelse fra de fleste høyttalerne. De første 25+ watt i ren klasse A vil virkelig få høyttalerne dine til å synge.
Go give these new over-achievers a listen and be prepared to be bowled over
The JC 1+ power amplifier is truly an achievement to the highest degree.
With JC 1+ amplifiers, the feeling of listening to a Steinway D in a real space was very satisfying.
Omtaler av Parasound Halo JC 1+
After several weeks auditioning the Parasound Halo JC 1+ monoblocks, I don’t really have anything to add to what Mikey wrote in 2003, other than to note that even with its significant increase in price, the improvement in its sound quality and the explosion in recent years in the prices of high-end, high-power amplifiers keep the JC 1+ competitive. This is a superb-sounding amplifier that will get the best from every loudspeaker with which it is partnered. Well done, Mr. Curl.

The Parasound JC 1+ Power Amplifiers are very high quality. One would expect that from the almost $17,000/pair price, but high price is no guarantee of quality for any product. It has to be verified. Proof of Performance for the Parasound has been verified. They are worth the price.

I’ve not heard any other monoblock entrant at or even close to this price that is able to recreate so many aspects of music with a more authentic voice. These amps are magnificent performers in nearly every regard. Honestly, I cannot think of a pair of monoblocks that offer a view anywhere near this close to the top of the heap for anywhere near their asking price. I can tell you that if I were shopping for a pair of monoblocks under $25,000, the Parasound Halo JC 1+ would be my first choice. Go give these new over-achievers a listen and be prepared to be bowled over by what you will hear. Most enthusiastically recommended. –
