Denon higher end integrates, Japan domestic market only...

Hello to all,

Denon offers 2 huge integrates only in Japan, anyone had experience with this units?

Oh by the way... trying to understand why they are huge and offers "only" 50W 8ohms / 100 4ohms

Almost sure that they are not Class A, and 100% certainty that not Class D, so... what about this amp’s technology? What the tech particularities that makes this amp provide this power specifications?

Appears that is some to do with this technology: Advanced UHC MOS single push-pull circuit.

Any thoughts?

Thanks!
