New Parasound Halo JC1+ monoblocks just released!!!

Total Harmonic Distortion THD has no real meaning anymore. And it hasn’t for 40 years. 

I bought a JC-5 a few months ago after auditioning the JC-1. I found the two amps to have a very similar sonic signature, but the JC-5 was slightly cleaner sounding. The speakers I was using were fairly easy to drive, so the added current capability of the JC-1 didn't come into play. Both amps could easily drive the speakers to high volumes. 

I've owned a dozen or so fairly high end SS amps from Levinson, Krell, Pass and Bryston over the years, and I'd say the JC-5 is easily in the same class or better.  However, the other SS amps are not recent models - mostly from the 80's and 90's. 

Based on my experience with the JC-5, I would expect the JC-1+ will be an outstanding amp, particularly for speakers that are more challenging to drive and need the high current capabilities.

Wondering if you asked the shop demo'er if the JC1's were in high or low bias mode, as I found high bias was much sweeter and transparent in the upper-mid/highs on the Wilson Alexia's, yet still retained the same hammer like impact and definition in the bass as low bias mode did.

Was in high bias mode, but fairly efficient speakers so maybe had less effect. 

I wonder if echohifi will be carrying these. Would be interested in bringing my modded JC1s for comparison with JC1+. I always found non-modded JC1s to be a bit dark with rolled off upper end. It is like listening to speakers with speaker grilles vs without when you compare non-modded JC1 to Empirical Audio modded JC1. I am not sure why Parasound advertise 25W of class A. Reading the Stereophile review the stock bias settings were significantly lower than recommended by John or Tony at Parasound. I don't push the recommended range on my set and I am in 55W and 58W of class A bias on my samples (assuming 8Ohm load). They do run hot though and in hot summer days that can be a problem (nice to have low bias mode when you need it). Last time I checked the bias settings I forgot to measure them in low bias mode, but they are probably half of power of high bias mode which is enough for many. I would be curious seeing how they measure. If I had a sample available I would have measured them on Audio Precision myself.
