If you're considering an integrated + power amp, then also consider a better integrated amp utilising your whole amp budget, integrated + power is not always better. Likewise, If you did get an integrated amp consider using your whole cable budget on a better single run of wire instead of twin runs of a cheaper wire.
Hence when you're testing speakers on the end of all this then don't limit yourself only to bi-wirabe models. Sometimes manufacturers make them single-wirable because that is how they will perform best. Often manufacturers will only include bi-wire terminals because the market demands it, even though it is to the slight detriment of the speaker's overall sound quality (obviously that's not always the case).
I find the naim supernait integrated is a great choice for use with a streaming system, especially one where the front end is something like a Sonos or Squeezebox where the limiting factor is the internal DAC, as then SN has a built-in DAC. I use mine with Neat Momentum 3i speakers.
To my earlier point, I went from a Cambridge DAC-magic/Arcam A32/Arcam P35 amp (so an integrated + power, just like you're considering) to the Naim Supernait and the latter is vastly better at a similar price. That's not to say that will always be the case, and you may find different, but it's worth keeping your options open.
