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


My favorite piece(s)  are  (and I still own them) the Martin Logan Ethos lousdpeakers and Soudsmith Paua cartridge.  As far as speakers go, electrostats are my favorite and will replace them with another set of electrostats.  I'm currently eyeing MUR Audio SP1's.  These two pieces make my rig sound great.

There’s been tons and tons of fine equipment in my house over the years.

The one that was the best, had a great sound stage, great rear facing baffles that just pounded out the bass, and was quick. The 1992 Ducati 888sps. Simply the sound from those desmo valves, yes all four of was wonderful. People could hear the sound from miles around. Dancing and shaking to that tight, responsive Italian bass.

There will never be one like her. They stopped making her 1994, next came the 916 and no one was the same.

Drag a knee an elbow too!
I have owned a Basis 2800 Signature vacuum / Vector-3 for about 8 years now which is probably the longest period of time I have owned any audio component, however my latest aquisition is my true favorite; the ASL Wave 8 mono's I recently bought on eBay for $450.00. This is twice the price they cost when they were new and they are worth every cent! I was not even concerned that one of the amps arrived with a blown cathode resistor as I was already planning to completely gut them and rebuild them with all premium parts. $450.00 later, I now have a completely rebuilt pair of Wave 8 mono's ready for another 20 years of blissful listening. 

Sota star sapphire 1992 cocobolo Still beautiful. Audio research sp -9 Mk III ear opener to dynamics,stoundstaging and imaging. Other components have come and gone but these are my foundations to what I think music should sound like.

My Klipsch Epic CF 4 speakers. I've had many very nice speakers and they are more dynamic and transparent than any of the 19 I've owned, including Klipschorns. Fourteen years and counting
