Best Home HIFi you’ve listened to

Gents/Gals: 

A general question on a “Total System” that YOU have heard at a buddies or acquaintance home. ( not a one night stand at audio show or retailer)
 

Is there a best system you have heard, that you consider darn near the best you can achieve ?  Or just the best sounding home system that a friend has, and you have spent some wonderful time with ?

or Maybe yours ? 

What kind of system was it ?  Components, etc 

Is there truly nirvana at a home
