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

• My favorits are Jadis JA30 monos from 1997. Latest ”uppgrade” are new power tubes KT120 from Shungyang, very pleased and closest you can get to NOS.
  
• Also have KT88 from Shungyang but changed to KT120 for it’s bigger ”soundstage”. 
• I also have to thank (deceased) Bobby Palkovic for his strong dedication and belief in Merlin speaker. I have VSM-X with uppgrades on filter and internal cabling, recently I added a 10 nF from Duelund on treble and mid/woofer section, it opened the top on each f-range spot-on.

My fave pieces are a pair of B&W 805Ss connected to a Creek 4330 integrated. I've had the Creek for over twenty years and I haven't heard anything like it since, even the (optional) phono stage is mega, quite an achievement for its size and price. The B&Ws are newer, about 10 years old and I can't see parting with them either. I compared them with a pair of KEF LS50s a while back (based on all the gee whiz reviews) and IMHO the B&Ws handily blew them away!  

Krell KAV 300r. It has a great tuner, and adds just the right bass to the speakers paired with it. For me it’s a keeper.

Sansui AU-717 Integrated Anplifier.  Still use it in my utility room, powerful and smooth sounding.  A little bright, but you can turn down the treble dial....remember those!

Also, still have my NAD 3080 Integrated Amplifier from 1980!  Never been recapped, yet it can still drive my old pair of Infinity RS-1.5’s into oblivion, with their 12” Dual Watkins Woofers.  Who needs subs?

Ok then Sansui AU 7700....

Any qualities he have it in some relatively high degree....

Versatile and more powerful than his official watts  measure and beautiful....

So good that i cannot part with it..... Way more costly to beat it....
