After 4 years the Tetra 406's continue to amaze me!
I have been known to 'occasionally' change up some of the components on our equipment rack, alternating between tubes and solid state amplifiers, CD players and a multitude of turntables and phono stages .... (man, that was an understatement - Barb)
The only thing I NEVER change are the 406's.

I love my 406's!
We have an old house, and the rooms are not large. With the 406's we get killer sound without having 2 monster monoliths taking up half of our living room (don't ask)
And ... they're sexy.
If I were stranded on a desert island I would get along quite well as long as I had my 406's ... a copy of Miles Davis' 'Bitches Brew', John Lee Hooker's 'It Serves You Right to Suffer', Pat Metheny's 'One Quiet Night', ANY Marcus Miller and Aerosmiths 'Honkin' on Bobo'.
