Umm, no. I am neither a noob or a shill. The person who quoted it may be but I am not.

from blog of Paul McGowan of PS Audio:

My friend and fellow audio designer Jeff Rowland came by to say hi the other day. Jeff’s always a welcome guest as he and I manage to nearly always be on parallel paths when it comes to product designs. I found Jeff and friend Tim Jerome in our listening room playing music on the new amp we’re working on developing. I’ve written before that this new amplifier is a stunning breakthrough in audio reproduction and to date I haven’t heard anything close.

The amp technology I am referring to is, as many of you guessed, based on the new Hypex class D technology and sure to form Jeff had independently made the same decision and was on a parallel path to building his own version.


Stuck in the middle | PS Audio

meanwhile it looks like Theta postponed the launch of their Hypex-based amp. so it looks like we found one of the mysterious names to use NCOREs.

Is it possible not one of the Hypex fans owns a scope? I asked several times about the amplitude of the output waveform in the absence of signal. Some people queried my motives for such knowledge while others promised to measure at first opportunity. Nothing so far...

I am asking something extremely simple. Hook a scope to the output, set sweep to free running oscillator frequency range (500kHz?) and get a reading of the amplitude.

You described your phono preamp getting upset if you power up your Class D amp. I did not fully understand what You ment by "even when it is not used" part. Did You meen that even if your amp (the Class D one) is not connected to any equipment (sources or speakers) powering up messes with your phono preamp?

Exactly that. There is a subtle change in phono pre noise and a not so subtle collapse of sounstage, change in tonality, reduction in microdynamics...
