The best? Best at what? Everything in HIFI is an exercise in compromise if you get my drift.
You have a million and one options. From Audiolabs, to the mentioned linn stuff, AVI etc etc.
Really depends what aspects of playback are important to you. Then I may also suggest you look at some good valve amps.
The old preconception of Tube amplification sounding warm, muddled and 'nice' ... forget it. Bad and/or cheap valve gear may sound like that, so do certain types of the breed such as some of the hopelessly underpowered 300B's. There are technical reasons for that but find a good one, and you could find audio heaven and in the process dont feel like upgrading for a long time! Good examples of the genre sound more dynamic, explosive and alive than most SS alternatives! Do yourself a favour and, if you can, listen to a couple. You might never look back. If you need pointers, let me know.
