Integrated amp recommendation

Try Sony TA-A1ES. A lot of amp for the money. Can be had for 1K used.

These are great suggestions, thank you! I am researching and looking primarily on the second-hand market, with mixed results in terms of availability. Am a little nervous about that, just had an unhappy experience on Reverb.com.

I have had a few god amps in my 6 decades of pursuing this hobby. Would suggest you consider spending about $1500 and evaluate Rotel Ai4 Integrated amp. Good DAC and phono stage with a large number of other features. Sounds Good. 

I personally use a Peachtree Nova 300-Bluesound Node 2i - I use the Nova's DAC-; Pro ject CD transport and Harbeth 30.1 monitors in a very small square room. Night mare(!) but after much stress it sounds pretty good for such a modest system. They are giving these Peachtrees away but they are a good value. Lots of power for the money (class D but think of the environment). I play this thing all day. If I was to change and spend more money I would just change out another integrated with DAC. MacIntosh or Luxman or Hi Fi Rose (no DAC tho). Good luck, perhaps spend more now on Integrated unit.

OP, I just listed a Cambridge CXA81 on USAudiomart for $850.  Would be ideal for you.  Use coax out from you Node2i to use the Cambridge DAC.  You won't be disappointed.
