If you want to hear what you WP7’s are truly capable of you need an amp with some power, real power. I have WP’s and although my Cary tube amp sounds wonderful on them, they can’t touch what my Pass X250 does. Your Wilson’s can really move if you have the right amp. Also the Wilson’s do not hold anything back so your source components better be great or the Wilson’s will sound harsh. If you’re only looking to stream maybe look at a PS Audio S300 amp, Bluesound Node as a streamer only through a RME ADI 2fs DAC using as both a DAC and Preamp. Should be able to pull this together under $3K keeping it as separates you can upgrade components out or add a dedicated preamp if you feel the need later.
Not heard a Hegel H190 but that could possibly be a contender. You have some serious speakers so if you don’t get it right you’ll know it.
