If i had the money.....

I'd be ordering a set of the Parasound Halo JC-1 Monoblocks. I knew that these were going to be good, but i didn't know just HOW good. I've talked to a few people that have them and the "reviews" of these end users is just as strong as the recommendation that these amps receive in the February Stereophile.

Hard to imagine beating a product that was designed for optimum linearity / performance by an audio legend, laid out by an RF engineer in order to maintain consistent impedances throughout the entire circuit and then building the circuit with each part hand picked to "voice" the unit for optimum sonics by a "tweaker". The total approach to product building for $6K a pair !!! All of this with POWER to spare !!!

THD is predominantly all second harmonic i.e. not the typical odd order that most SS amps generate.

IMD of .0015 !!! Keep in mind that distortion typically goes up quite noticeably as power is raised and impedance lowered. This figure was taken at 4 ohms and at 600+ watts of output !!!

Output impedance of no higher than .06 ohms. This amp should keep the same "voice" and stability into just about any speaker. The power output verifies the stability and "robustness" of the circuit also....

Rated at 400 wpc @ 8 ohms

Power at clipping, broad band signal steady state:

8 ohms: 545 watts

Power at clipping, pulsed 1 KHz signal:

8 ohms: 586 watts

4 ohms: 1154 watts

2 ohms: 2255 watts

1 ohm: 4200 watts !!!

Any thougths / comments on this one ? Sean

From the literature it is Class A up to 25 watts and apparently there is an internal switch to bring it down to 10 watts if you do not want the heat. I think the JC-1s
are going to be the standard which all other solid state
amps will aspire for the price. I heard there will be a
matching preamp in the future. BTW, isn't the Blowtorch
preamp from the same set of designers?

Sean, as far as Spectral is concerned, I have NEVER had an oscillation. Neither the DMA50s nor the DMA200s have ever
had problems, oh I can blow fuses, but Spectral
stuff have tons of protection. And Sean, you can purchase
used a 200 watt DMA200 for under $2K! The thing is built like a tank and is absolutely drop dead gorgeous inside.
Personally I like it better than all Spectral amps
except the DMA360.
Idle is 800 watts, and it puts out the heat!
