ATI 2007 or ATI 1807


I am contemplating on one of the above. I have a small listening HT room
10ft x 10ft and I am presently using a Yamaha AVR RXA-3010 in a 9.2 set up.
I am planning to hold on to the Yamaha for now and use it as a pre-amp and buy a ATI 1807 or a 2007 for better dynamics and so on..
It their a huge improvement in sound quality with the ATI 2007 to justify the extra cost over the 1807?
I would be most grateful for any advice please.

My speakers are easy to drive. I am presently using Monitor Audio GX200'S and GXC350 for centre.
Thank you for all you most helpful replies..so far. Please keep them coming..

Thanks Bob.
Can anybody confirm please?
Is the only difference between the ATI 2007 & 1807, Twenty watts of extra horsepower and balanced connections?
Many thanks,
Morgan.
The 2007 is fully balanced from input to output.The 1807 is not. The circuitry is fully balanced, not just the inputs. That cuts down on noise with the unit itself. So, the difference is more than just balanced connections. That said, I have never compared the 2007 to the 1807, but I am happy with my 1807.

I agree with Bob on the general characteristics of the sound, at least for the 1807.
Thank you Dtc for your response.
As I am off today, Monday- I called Jeff in ATI Sales. Yes, he confirmed that, yes Dtc that you are correct indeed. He said the amplifier is fully balanced, not just the balanced connections and that all of this contributes to less noise and the longevity of the amplifier. He said a little bit more...all good it seems. Some of it just flew over my head, as it was technical stuff I did not fully understand, but it sounded marvellous!
Finally, he did say- "but I cannot guarantee that you can hear all of these differences"
Looks like I will opt a 1807, but it is a tough decision. I always lie to buy the best..
Anybody out there with a 2007?
Thank you all who contributed to my question.
