Well I don't know much about how to interpret specs, but these are one of the speaker sets I tried with the WiiM Amp.

I normally use them with my Linn MDSM/4 DAC/amp, but they sounded pretty good with the WiiM Amp, taking away some of the glassy brittleness I thought it had.
I think you should maybe try the WiiM Amp from Amazon - their return policy is pretty good in my experience, so go for it if you can. If it doesn't work out, you can always return it but I suspect that once you hear it, you won't. Best wishes and good luck
