Given the choice of a tube or hybrid integrated amp, I'd agree with Peter_s and recommend trying a tube integrated amp. Your speakers are sufficiently sensitive to be driven by a 40 wpc tube amp, provided the room is small to medium size.
You might look at a used PrimaLuna Prologue 2 or Rogue Cronus and see what you think. However, neither of these amps is going to be particularly colored. They are going to sound more neutral than otherwise. I have owned a Rogue Cronus, and I have heard he PrimaLuna at CES.
If you buy used, you resell it without taking a big depreciation hit.
