High end Vintage SS amp vs the best Class D amps

[Mart68]

but your Sansui is still working after 50 years. Will the Topping have that sort of longevity?

I like to think so but I doubt it.

I have to say that class D killed my loved Sansui..

Was this comparison done with basic controls? Could you describe them?

Thanks!

You're damn right. I've just recapped It, good for 50 more years
And I can't compare the object...
This is why I'll always keep my old Sansui

Was this comparison done with basic controls? Could you describe them?

Yes, subjective comparaison with same input (Roon Qobuz Source > WiiM Pro > Sansui / Topping) and basic controls.
Basses are similar, but for the Middle and some Highs, the sound is really more detailed and rich.
Notes are more articulated, more dynamic... and 0 noise O__O

Voila

and basic controls.

What specifically were your "basic controls" and how were they implemented?
