Finally, The Class D Holy Grail?

[fas42]

What has been optimised is the global negative feedback to produce the excellent distortion figures, in conventional testing. Whether that translates to anomaly free sound in real world situations is the question mark; just saying " The module places no particular demands on the power supply quality." is a nice selling point, but I would want someone to try comparing using an excellent PS with a really crappy one, and tell me that they could hear zero difference in the SQ.

I'm certain that a well done implementation of the module in a finished component will produce sound second to none - now, just have to wait for a value for money unit with those qualities to come on the market ...

Didn't anyone else notice the high THD at its rated power? Output Power 450W @ 1% THD, 4Ω, yet they claim it sets a standard for power amplifiers of any class...

That's not very impressive from my perspective.

 

 

Standard way of spec'ing, for engineers' benefit - it tells them how much power it can deliver at the onset of clipping, 1% means that you've reached the limit of the design.

 

The distortion just prior to that level tells the story - this is exactly how a good design should behave,

Hello Everyone from a newbie of this Forum,

The problem with these Class D amps is... due to the same Hypex Module ..could be  the same sonic result .. Channel Island , Bel Canto , Molla Mola Kaluga , Nord , Merrill... etc..etc.. between them .. or am I missing something with my question?

 

The basic rule for audio is, or should be, is that the closer one gets to optimum sound, the more the tiniest thing can make all the difference - the slightest variation in the implementation, the way a manufacturer builds in a module, could have a huge impact on the subjective SQ - there is a lot added by the "boxer", .

 

IOW, using a high performance core to a component increases the pressure to make sure every other part matches up to that quality - if one wants to get the best from the overall ... it doesn't get easier, it gets harder!
