Is this a cheaper alternative to Devialet?
#5
From Nuprime first diagram in the provided link, class A and class D amps are clearly in series (like in other hybrid amps): not in parallel as in Devialet's ADH.
If the THD of Nuprime's class A inside their hybrid features a good THD of 0.0015% (yet without specified conditions) and so is the noise (-130 dB), the THD of the overall system raises to 0.005% (5x worse than Devialet) as well as SNR severely drops to an average 95dB: class D obviously downgrades class A's performances in IDA-8, whereas in the white paper of ADH, I read the contrary.
So from a technical point of view, you may only have a very little taste of Devialet.
