Phil, congrats on your ProAc purchase. I've owned Tablette 50 Signatures for 9 months and during that time have had them hooked up to a Simaudio Moon I-5, Electrocompaniet ECI-3 and now to Blue Circle Audio BC21/BC22 separates. For me the Tab 50s sound their best with the Blue Circle setup. By far.
I've heard other people say that ProAcs performed best when run with tube equipment, and my experience bears that out. With the Simaudio and Electrocompaniet, my ProAcs sounded thin or glassy at times, but having a tube preamp cured all that. Through the Blue Circle gear my Tab 50s reproduce female vocals and acoustic instruments with startling clarity and warmth. And boy-o-boy you'll love the way your 1.5s will image once you find the right amp. Wide, deep and very focused.
My suggestion would be to look into and try to audition Conrad Johnson, Rogue Audio and Audio Research gear for starters. The Threshold amp might work, but I would consider mating it to a tube preamp.
Good luck and let us know how it goes.
