Welcome to AudioCircle, Brad!
There are a lot of integrated amps with built in DAC, phono preamp and network streaming, like Marantz, Denon, Cambridge Audio, etc. There seems to be two categories: $700, 50W; and $2000, 100W+. The more expensive models will generally sound better and not just because more power, they can afford to make better circuit design. But you have to judge for yourself whether it is worth $2000 with $1200 speakers. Remember you are getting DAC, preamp, and phono pre all in one box, so the more expensive amps are still pretty good price compared to buying separate budget hifi components and cables to connect them.
Buy them from somewhere where you can easily return for refund, like Amazon or Crutchfield. Buy a few at the same time and compare.
Your speakers are advertised as 87dB - 8ohms, but
they dip below 4 ohms in the bass. Fortunately, where they dip to 3.7 ohms minimum, the electrical phase is not negative. So you should be able to use one of the integrated amps in the $700 category which say 4 ohm load. But I'm quite sure that the amps in the $2k category will sound better, especially at dynamic peaks. If you listen loudly or to classical music, or worst of all to loud classical music, then I'd make sure the amp can make >=100w into 4 ohms with less than 0.1% THD. If you listen at moderate normal easy volume levels to popular genre music (compressed) like classic rock, jazz, etc, then 50W should suffice.
