Definitely, you become accustomed to the quality of your system.

Nothing like listening to a system making some of your favourite music sound awful to appreciate your system.
I never seem to find the time to listen to my hi-fi. It's a bit elderly but it's still half decent...
Nakamichi Cassette Deck 2
Rotel RCD 865 (One of the early bitstream players - won numerous awards)
Cyrus Two Amp + PSX
Cyrus 780 Speakers.
Can't remember what cables + the stands are.
My Dad has a slightly older Nakamichi and an early Rega Planar 3 which virtually never get used.
