My favourite that I own now, is the Daedalus Audio Da-RMa speakers. I travelled o the UK to the Rocky Mountain show in Denver in 2009 and bought them from Lou, as a retirement present to myself. I still worked for 5 more years but a great present, that I am keeping for ever.
The favourite item from the past is the Koetsu Rosewood Signature cartridge I bought second hand, used for 3 years, retipped and sold for about what I paid for it. Later I used a Koetsu Onyx, but I didn't like it as much
