Parasound Halo JC-1 for Thiel CS 5i

^I'll hazard a guess that it's not the 4 Ohm load that's the issue.

As I posted earlier: Krell.

dsper Hi, Well, here is the latest on the great experiment with the Parasound A21.

At 11 o’clock on the preamp while playing Fleetwood Mac "Rumors", the A21 one started to clip and went into protection mode.

I routinely run the W4S ST1000 at 2 o’clock with no problem.

The answer is 400 watts into 4 ohms is not going to cut it with the Thiel CS 5i’s.

Any other suggestions beside the Parasound JC1’s?

Input Sensitivities.

Parasound A21 =1v

WFS ST1000 =2.95v (yours)

WFS ST1000 mkII = 1.31v

These are the input voltages needed into to make each amp reach it’s maximum output (watts) before distorting or shutting down or blowing up.

Now you can look back at your 11 o’clock and 2 o’clock preamp statements and see what’s happening.

And as I said the A21 will drive them but the JC1’s are the real deal, as for the WFS it’s class D, ?

No I don’t, wish I could, in Australia they are over $18k. And to buy a s/h pair in the US is cheap enough, but shipping for me is a huge cost, and then I’d need to convert them to 240v, but this could be just a primary transformer tap change if lucky.

I have something similar two pairs of ME850’s (long out of production) but very similar topology to the JC1’s.

My reviewer friend Edgar Karmer for HiFi Australia, 6Moons, and who also owns Audio Esoterica magazine has a pair of JC1's, and they were the best thing (beside an ME1500 also out of production) we found from many to drive his Wilson Alexia’s with, which are also a bitch to drive.
