@cannata i assume you must reside in Europe?
If so , Spectral must cost close to Ch precision?
However , I’d urged you consider listening to the new SV amps from Spectral.
The 300Sv stereo amp is so clean pure and low distortion.
The Sv monoblocks most likely take this even further.
A full “ SV “ Spectral system is quite special indeed.
But , I’ve never heard Ch so I can’t comment on the differences between the brands.
