Parasound Halo JC-1 monoblock amplifier


Does anyone have any information on this amp?
Does it run hot?
How will it match up with a VTL 2.5 tube pre-amp?
Are there any particular characteristics to its sounds...i.e, warm, transparent, etc?

Thanks in advance.

The Parasound JC-1 monoblocks are wonderful! I use them in conjunction with a Tube Research Labs modified Marantz SA-14 SACD/CD player, Aesthetix Calypso tube preamplifier and a pair of Wilson-Benesch Discovery loudspeakers.

The JC-1 solid state amplifier combines the warmth/sweetness of tubes along with the bass control of solid state. Stereophile measured this amplifier outputting 4200Watts into a 1 ohm load so it is a brute.

They sound best in high-bias mode which generates a fair amount of heat. If you have a large room, this will not be a problem. With a smaller room it may be an issue. In my room 12.5X16.5, the temperature got quite warm, especially in summer. You can reduce heat generation by keeping the amplifiers in low-bias mode and only switch to high-bias mode for serious listening. I ended up moving the amplifiers to a basement shelf, directly underneath the preamplifier (on the main floor) which solved any heat generation issues. However I know of others who absolutely loved the amplifiers but couldn't handle the heat generation and ended up selling.

The amplifiers are special, so make an attempt to accommodate them.
