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

If you like the Marantz house sound, a touch warm and emotionally connecting but with detail, there is a Marantz PM 8005 integrated amplifier for $800 (it lists for $1,200). It is made in their reference factory in Japan and sounds great. It does not have a DAC, but the Marantz SA 8005 is a nice DAC + SACD/CD player. One is available on Audiogon now for a good price as well. I own both models and think they sound great.

Schiit recently released the Modius dac for $200.  I've had a few of their dacs and they really make great sounding gear.  I've had the Modi 3, Modi Uber, Bifrost Multibit among others.  I'm waiting for my Modius to arrive.
Any dac advices ?? I need a better one comparing to in-built dac in marantz pm6006
Thank you for valuable advice, lastly what DAC should i prefer to maintain the sound i have now
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
The Exposure amplifiers are considered very good. I would probably look for a 2010S2 as it would have more life left in it.  
A Yaqin tube integrated around 40-50wpc.can be had for your budget & with your speakers probably blow your mind...
