The SHL5+ requires some power to wake up. If going tubes I would recommend a stronger amp with 35+ watts. I’ve tried 30 and under and it simply wasn’t enough. The MastersounD BoX and Triode TRV-88ser did well powering them. I don’t recommend Single ended amps with these unless it’s a beefy parallel Single ended one.
On on the other hand, the 30.2 absolutely sings with a modestly powered tube amp.
