I have a built in advantage: no wife. And a Husband who is sympathetic, and a collector of movies. Music to a lesser degree.
Collection takes up 2 full rooms and part of three others. A TREASURE HUNT!!
Where should I begin?
DVD-V and BluRay videos/concerts: lots still sealed
Most ridiculous example of sealed product in my collection: Movie Box - Genesis 1981 - 2007 5 DVD-V 5.1 Bought first week of release. I bought the other Genesis/CD/SACD/DVD-V boxes and listened to/watched each disc at least a couple times. I've revisited the other boxes in the last couple weeks. I believe this is the only box set by anyone still sealed. This one is long overdue.
Sealed product that won't be opened by me: several duplicates of CD & SACD.
I haven't listed VHS, Beta, LD or DVD-V and BluRay movies. There at least a couple that I've never viewed on each format. Mostly bequeathed not viewed.
DVD-V equivalents of BD in some super deluxe boxes. BD's in those were played.
CD's: a few dozen. although I estimate 20,000 RBCD's, I have listened to the majority of them at least once. A few thousand likely need a second spin. breaks my heart.
2 ch & mono LP's: perhaps 100, mostly LP's I was bequeathed
BDA, DVD-A, DTS CD, Dolby Surround CD, DVD-V 5.1 albums and SACD multi, 2ch & mono: NONE, though I've not played most of the 2ch mixes on 5.1, alternate mixes of album, or CD layers of hybrids.
Quad LP's: none
Q8's: perhaps 100 that I was bequeathed, many doubles I already own.
2ch prerecorded reels: perhaps a dozen
78's & 45's: none
Elcaset, Tefifon, Playtape and Edison cylinders: none I know of lol!!
MD: Boz Scaggs Hits! I play Japan version or US version on CD often
Assorted pre-recorded cassettes & 2ch 8 tracks: a few dozen I was bequeathed
BTW; bequeathed infers that I was given these by friends, often posthumously. I have never asked anyone to do that. Even a line in their wills! Everyone who knows me understands IT's MY JONES!
