Marantz pm6006 upgrade?


I'm looking for a new amplifier, reason why i bought this marantz was the built-in dac but now i am considering an external dac + amplifier.

I am considering Exposure amps (1010 or 2010). Can you suggest any amps (im okay with used ones) better than this one under 750 dollars. 

My speakers are Cabasse antigua mc170, preferred music genres: jazz, alternative rock, pop

A Yaqin tube integrated around 40-50wpc.can be had for your budget & with your speakers probably blow your mind...
The Exposure amplifiers are considered very good. I would probably look for a 2010S2 as it would have more life left in it.  
Ah, it's an integrated. I was not aware of an amp with built in DAC

Run to Underwood HiFi. He has a couple new W4S integrates at outstanding prices
