I got a very slightly used Innuos zenith Mk 3 for $3500 here on Audiogon. I could not afford the $5500-7000 the new streamers I want were costing. It's really good. Innuos Sense software is really reliable so far. If you have a sensitive system that reveals when sources sound good or bad, don't cheap out of a streamer, especially if you have a decent DAC. My previous one was the Ifi Zen stream in my revealing system and there were definite sound deficits. I had to go upscale. I agree with the Impulse or Auralic brand suggestions here. Get the highest level you can afford.
