Devilboy, I have owned two amps that sound very close to tubes:
Electrocompaniet AW180 and McIntosh Mc402.
I do not agre that Rowland, Nuforce, Krell or Symphonic Line sound like tubes. Those are good amps but they play clearly in the solid state league, Krell being the most forward-sounding.
Rowland and Nuforce class D amps lack upper treble "air" due to the mandatory Class D low-pass output filter, however that's not tube sound in my book.
Good luck with your search.
