Parasound Halo JC-1 for Thiel CS 5i

Thanks for the responses and Happy New Year!

Another fan of Thiel loudspeakers here as well. These things "crave" high-current in order to really open up nicely!

You might want to check with Parasound regarding 2 ohm loads. I believe the JC-1 is spec'd for 4 ohm loads minimum.

I am driving B&W 803Ds with a pair of JC-1s, and they have a minimum impedance of about 3 ohms. No problem with those, but 2 ohms is quite a bit lower.

I don't think the JC1's will have any problems with a 2 Ohm impedance swing.

"With continuous drive, the Parasound clipped at 545W into 8 ohms (27.4dBW)—way above the specified 400W. ("Clipping" is defined, as usual, as the power level where the measured THD figure reaches 1%, and is shown in fig.7 as the horizontal magenta line.) With a low-duty-cycle 1kHz toneburst more representative of music, the Halo was a powerhouse. Its clipping power increased by 0.3dB into 8 ohms, reaching 586.5W at 1% THD (27.7dBW, fig.7, black trace), with 1154W available into 4 ohms (27.6dBW, blue), 2255W into 2 ohms (27.5W, green), and no less than 4.2kW into 1 ohm (27.2dBW, magenta). The latter is equivalent to an output current of 64.7A!"
