So just how much vinyl do YOU own?

At one point, well over 1,000.  My three sons, who are in their 30's are into vinyl big-time, so I have given most of the LPs to them.  Have kept:  Beatles re-mastered, McCartney Archive Collection, America, Beach Boys, Chicago, CSNY (collectively and individually), ELO, George Harrison, Billy Joel, Elton John, John Lennon, Tom Petty, Pilot, Todd Rundren, James Taylor, They Might Be Giants, Brian Wilson, and Frank Zappa.  Literally, everything done by all of those artists. 

I estimate about 15,000.  Includes many genres rock, jazz, blues, country, classical, folk, pop etc. I've been collecting for over 60 years.  Most are in very good to near mint condition, as I used to record new records on my reel to reel or cassette tape recorders and then put the LP away. Now I am just playing the records whenever I want.  I have two playback systems in my basement listening room and one system in my living room.  I have restored several turntables that I rotate in the basement systems including Thorens TD124, Thorens TD124 II, Garrard 301 and 401, Linn sondek LP12 with all the upgrades.  I use several tonearms and carts of various vintages.  The same is true of my electronics and speakers.  It all depends on what I'm listening to.  I've modified my old JBL L100 speakers with three way monitor quality crossovers same for my JBL L7's they sound great for rock.  My Tannoy Berkeley 15" HPD385A speakers sound great for jazz and classical.  I use Revel Salons, ALTEC Lansing 604-8g 15" drivers and crossovers as well.  They all sound great and Its all fun.

Well, I now own 20 more records than I did this morning! Stopped in one of my LRS's and they had the dollar bin on sale - 10 for $1. Spent $2 and walked out with 20 LPs. Now comes the hard part. Cleaning, listening, culling. 

Sticking to plan, I need to remove at least as many records as I picked up. So, hopefully I'll keep a few and trade the rest for better records.

As far as bargain bin buys at LRS I fear there is little hope for you or myself!

I cant even go out of state for work without coming back with more albums!

Not a lot considering I've been collecting since hearing "Sunshine of Your Love" when in the 7th grade. Had a decade of not purchasing in the 80's due to raising a family and work priority. I'm sitting at +/- 6K LPs and 2K CDs. Though I hope to live another 40 years, the media and equipment are distributed in my will. 
Keep spinning and streaming folks.
