Good amp for Tekton lore s speakers?

I'm a long time audiophile who is finally getting a decent system together. I have an old Yamaha a1000 av receiver I use for stereo only, and just bought Teton lore s speakers as a first step to overhauling my system. I listen in a large glass room with carpets (i cant change the glass or put up room improvements) to a wide variety of music, mostly from my macbook itunes and cds, from opera to reggae to folk. I am attracted to the idea of a warm sound from a tube amp but a bit put off by the costs and the low wattage. I like to hear detail and bass at a moderate to low volume, and I like bass to have a punch, not be mushy. Right now the sound is okay but the bass is lacking, I like the mids and clarity but don't like the forward sound, which can be harsh. Can anyone recommend the best way to spend about 1500 dollars? I am using thick copper Home Depot electric wires and monster interconnects. I have pondered a dac, but am focused on an amp, but am unsure if I should try a high wattage emotiva, a low wattage zen tube, peach tree audio all in one, or if there is something else out there. Many thanks for any ideas.
