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

As much as I love listening to audio, when it comes to physical possessions I'm 'way more emotionally attached to my musical instruments and to my record collection. That being said, I guess I got to say that my favorite component is my PrimaLuna Integrated.  Not only does it give me lovely, immersive sound, when something gets noisy it's fun to turn it upside down, take off the bottom and squirt Deoxit on the offending knob.  The 'Luna is so wonderfully straightforward and un-tweaky.  Then again, I've suddenly developed an unmistakable yen to audition a Grandinote Shinai.

The company/name may be so long-ago and forgotten I couldn't find it on google (or is my memory faulty?), but the Transistronics Integrated I had prior to my Kenwood KW40 was definitely the worst piece of equipment I ever had. It was my first step-up from the fine-sounding Heathkit mono amp preamp combo I got from my dad. Did I get it from my uncle? In any case, gritty, dirty, trebly. I was a happy kid when Dad sprung for that Kenwood after we heard it at the hi-fi show.
