Best 2 Channel Integrated Used for under 750?

Personally, I would go for a tube integrated. In my experience, the overall musicality and enjoyment they will provide will be head and shoulders above any solid state or hybrid, in addition to being quite reliable and headache free.

Given your price range is $750, I suggest you look into Chinese companies such as Cayin, Consonance, Jolida, and Prima Luna. The Rogue Cronus is another to consider, but a few hundred more than you've stated your goal being.

The units put out by Outlaw Audio get rave reviews. I believe they are only available online. Check Stereophile's review.

Myryad Z140 is stellar for the price. The Audio Refinement Complete is also a great recommendation. Check out the Creek 5350SE as well - it is much better than the NAD 320BEE IMO.

Another to consider is the Onkyo 9555; excellent piece for the price.

What speakers are you using???

I just picked up (from here less than a week ago) a Jolida 102b and I'm just loving it.

But before making any recomendations I would need to know a bit about what you have and what you like.
