My Thiel 3.6 speakers and Mark Levinson 23.5 amplifier. I really didn't feel the need to change since this combination came together. I have changed few items such preamps and DACs, but Thiel/Levinson continued to amaze me whether it is a brand new recording or a less than perfect mono recording from nearly a century ago. This combination made it very hard for me to leave my listening chair once the music starts playing. Both designs are achievements in near optimal balance in engineering and art.
