As Al mentioned, your speakers aren't ideal for tubes. Why don't you change speakers first? You could look for some that are friendlier with tubes and then have a much less restricted assortment to choose from.
FWIW, I have b&w 804s and McIntosh MC275, so also like tubes.
Also include Linear Tube Audio in your list of amps.
