Music Used (Genre/Selections): Anything loud.
System Goals/Comments: I picked up this Denon wayyyy back in 2007 mostly by accident. I didn't know anything about it other than it was big, heavy, silver, and seemed to be pretty decent since it was just an integrated pre/main amp. I brought it home and used it for 4 years till I got my Motorola monoblocks; which by that time it was developing the dreaded input and relay issues.

When my monoblocks decided to blow tubes "for the last time"; I examined the Denon and found one channel seemed completely dead. I assumed all those old caps had finally failed and that my dead channel was an electrical problem. When I finally decided to power the thing on enough and risk blowing the output transistors....I was very happy to find that it had no major electrical problems....my dead channel was due to a dirty output relay and completely failed input selectors. I bypassed input selectors and cleaned the relay. While I plan to recap it soon...right now that tank is humming away...gladly providing me that pure analog sound that made me get serious in to gear in the first place.

In Steptember 2019, a nearby lightning strike destroyed most of my stuff....except the Denon, Sansui, and tube gear. A cheap DAC made an attempt to replace the SMSL M8 before just dropping the money on an SMSL SU8.
