What's the best and/or favorite piece of equipment you've owned? And do you still own it?

My Decware Rachel integrated. At low levels, that thing was sweet as hell. The midrange was to die for. I wish I had kept it instead of selling to upgrade. 

Original Rogers LS3/5a 15 ohm , purchased new in 1975.  Sold in mid 90s along with all my other equipment to raise cash to start a business.  Ted to see them go, but the business was the best decision I ever did.  I could buy them back, many times over, but, kind of like the high school sweetheart- reality probably not as good as the memories.

Linn LP-12. It still makes music.

Lafayette KT-550 tube power amp for one.  It was built in the 50s and still kicks the ass of most any amps I have ever heard even in stock form.  Other than that, the large Ohm Walsh I had in college playing dark side of the moon.  After that it is all the products I build.

Happy Listening.

My Sonus Faber Electa Amator speakers. They are the original ones, bought new in the 1990's, with the marble/walnut stands. If I can pick two, it would be my Stax headphones (currently 009s).
