Need help picking a streaming integrated amp

Perfect unit if it sounds good. Thanks for the tip.

Several options depending on budget.  Since you're open to Naim, that'll give you plenty of choices.  These are ones I know of:

At low end of budget, Yamaha R-N803 - $700ish.

Bluesound Powernode 2i - $900 (I have the previous model Powernode 2).

Marantz pm7000n - $1,000.  I'm about to take delivery on this to replace my Powernode 2.

The NAD's mentioned above, I think under $2k.

Hegel H90 at $2k, or Rost at $3k.

NAD M10 at $2.7k.  NAD coming out also with an improved version of this soon.

Upcoming PS Audio Strata - $3k.  Probably available mid summer.

And the Naim family you mention.

That's what I know of in the budget envelope appropriate for the speakers you have (there are many other cheaper options but I wouldn't recommend them, especially if you are open to Naim level quality and don't need to skimp).

Note:  all of these are all-in-ones, so-call super integrateds.  If you are open to two-box solutions, there are many more possibilities, and I'm sure there are super-integrateds that I missed as well.  

many thanks for very good info

Preowned Devialet 120... very good/excellent built-in phono, stream via Audirvana (or equivalent) on a Mac or PC over network (Ethernet or WiFi) directly to Devialet. Impressive functionality and sound quality in a true one-box solution.
