I can't say whether it's the best as I haven't directly compared with others you have lsited, but I'm listening to the Triode TRV-35SE as I write this and am really enjoying it. This unit has EH 6CA7s and NOS front end tubes which are a welcome improvement over the stock compliment.
As always, it will also depend on the interaction and synergy between your speakers and the amplifier you choose.
Good luck!
