Item: Parasound JC1 Monoblock Amps
Location: Sydney
Price: 6,500
Item Condition: Used
Reason for selling: Settling in with tubes amp
Payment Method: Pickup - Cash, Paypal, COD Only
Extra Info: PICKUP ONLY - NO SHIPPING. Second owner. I would like to sell these rather than being unused because I'm quite content with my tubes amp. Still have boxes available. Even though these are 400w / 8ohms each, Stereophile did a measurement test and the true numbers are somewhere around 568w/8ohms each! Very powerful solid state amps that can drive any speakers on planet earth (even Bose!). I used these to power my Dynaudio C2 and they power them without any sweat, even though Dynaudio C2 are famous for being difficult to drive. Happy to provide demo for serious buyers. The amp was designed by the famous John Curl, read up the story about this amp and you will be convinced that this is a serious piece of engineering and they did not skim with the components inside either. There are minor scuff marks on the chassis which is quite normal for amps at this age. 
The JC1 runs in pure Class-A up to 25 watts at eight ohms, with its bias set to high and ten watts into eight ohms with the bias set to low.

 

These amps are still being sold on hi-fi stores in Sydney for $9,000 EACH. So grab a massive bargain, it's a no brainer to get it at this price when you could have spent $18,000 for the pair.

Heard these with the matching preamp on a pair of Kef Blades, among the best showroom sounds ever heard. Detail, imaging, slam and mid voicing extremely good.

Fair enough. Know how you feel. GLWTS again... The next owner will definitely really enjoy them. Very powerful amp, great highs and bottom end! :)

Incredible end game amplification, mine are keepers, I cant imagine my system without those two big powerhouses sitting at the bottom. Absolute bargain to be had here, should not last the day. Would suit power hungry B&W, Dynaudio etc beautifully. My Lenehan ML5 Ref adore them. GLWTS

Ok, good to know. I don't know who takes any notice, haha. You must be going somewhere very special from here.

 

Who survives without music? Only those undeserving of life's blessings, I assume.

Love the feet shot. Why do feet seem to relate to Hi Fi?

Love these amps.

I should ask how old would these be? I am tempted.

 But no postage! If postage is possible I may PM an offer?

Hi Hazzzy I'm the second owner. It's been in my home for maybe 8 months-ish? Definitely less than a year. Maybe gambit1870 can chime in regarding the total age?

 

It's pick up only at this point unfortunately.
