What has been your most satisfying component?


I don't think I have seen this question asked so here it goes. Many of us tend to buy and sell looking for the ideal, the holy grail, what works best in the current system, or whatever.
What component (or components)have stood the test of time in your system? I've been through quite a few but some have stayed despite having bought their replacements and subsequently selling them. I'll share once we get a few posts to get things going.

good thread. since 1984 i've had 3 pairs of b&w 802's (most recently matrix s3's), so there must be something there i find appealing....the mainstay has been the mac c22 II. my second favorite pre of all time(next to the marantz 7), and its not going anywhere.
I have two. The audio refinement complete. I've managed to own it five different times. I've sold and rebought. I think I'm sticking with it now. Even if I choose to go with another amplifier.

The second one is a mint condition 1978 Yamaha T-1 tuner. I bought it about six years ago and is the only piece of gear I've ever had for more than a year. I don't see it going anywhere. I have owned a couple other tuners, but the T-1 stays around.
Micro Seiki MR-711 turntable with MA-202L 10" tonearm. I've done the Linn, Thorens, VPI, SOTA, Ariston thing, as well as some of the better direct-drives, Denon DP-6000, etc. But this is the table for me, the day that it came, I put my DDX-1000 with Grace 714 arm up for sale.
Audio Research LS-3 preamp...
solid, transparent, performs well w/ SS or tube gear.
The JRDG Consonance preamp w/phono- for approximately $3500 with the line-stage upgrade and sorbothane treatment which came a bit later (stereophile never acknowleged the new mod even though they gave a very favorable review to the original preamp). a very quiet/great sounding AND inexpensive mm/mc phono stage ($300) which i never felt the need to replace, was included. AND, with the new line-stage module ($450) there was easily a 25% improvement in the transparency of the piece. even after experimenting with some fancier preamps much later on, there was improvement in some areas, but the Consonance still sounded great. i see these going for $1000 on audiogon and i just have to smile a little- this was THE FIRST REMOTE CONTROL PREAMP ON THE HI-END MARKET, and the remote is still one of the best i've seen (200 volume steps, one at a time or 10 at a time), a big chunk of metal with phase, record out switching, mono, virtually everything is on there. inside the preamp you can set input and output impedence, plus a whole lot more YOURSELF without tools or solder. IMHO it's pretty special.
