In my five or so years in this hobby - I have not really come across an experience to where I hear a system that just sounds completely -right. Just the same, there are a few components that really hit above my expectations..
The Totem Acoustic 'sttaf' definately has to make the list, as its the only piece of equipment I have kept, and will not get rid of. I have owned plenty of 'better' speakers, let alone hearing a whole boat load I havent owned. There is just a certain magic that this speaker has. In fact, the overwhelming thing about this speaker is its ability to not blow me away, yet still has surprises for each recording - making everything a unique experience!
Second, would be Vinnie's stock clari-t. I may not go so far as to claim its a giant 'killer' - but she certainly is a giant. This unit taught me what 6 watts of good clean power is capable of..even driving average efficiency speakers with aboslute ease. Great sound for a great price if it meets you needs.
Third, yet another class D amp - the Teac Legacy 700. For $99 (and even the $199 retail), it was just astounding. We've read enough about it here so I do not need to repeat myself. I put this amp against the big dogs and it held its own every single time.
