The KI Ruby has a very good blend of a sweet tube like sound but with tons of current on demand .the Ruby is grossly underrated in power it says 100 wpc
in fact it is 170wpc into 8 ohms and almost 280 into 4.
i have been into audio over 40+ years the mstched parts quality is very high
and the active preamp ,with seperate power supplies and seperate power for linesr microprocessor volume that is out of the circuit once done adjusting
and excellent analog section the 2 dual mono N core amp modulesare direct coupled to the a Loudspeaker terminals ,and all connections Copper.
And copper clad chassis for extra magnetic isolation ,it has exceptional build quality and made in Japan ,not China ,Ken Isawada had just retired after 40 years
with Marantz,passed away several months later ,RIP Ken.
this was his final effort , the KI 10 is 2 x more powerful still , please note upgrade the 2 fuses and good power cord for a noticable increase in resolution .
since it is a bit warm if you want a bit less buy the Hifi tuning supreme fuses
and buy next size up for stock fuses can vary over 15% , and to have a fuse pop on start up is $$,
