First of all, I wanna thank you all for your effort.
After all, I have decided to stick with an Integrated Amplifier and go up a notch in my budget and manage to narrow down to 3 int. amps :
Cambridge Audio CXA60 $749
Yamaha A-S701 $799
Cambridge Audio CXA80 $999
I have a couple more questions as well:
1. What sets the Cambridge Audio CXA80 apart from the CXA60 and Yamaha A-S701? Is it the features or sound quality or something else?
2. In your opinion, (since sound could be a subjective matter), what is the best $1000 integrated amplifier?
I have absolutely no problems going a bit beyond the $1000 mark if it is really worth it, so any suggestions will be much help to me!
1. The CXA80 has the asynchronous USB input that could be useful if you play music from a PC but want to use the CXA80's build in DAC. This amp does not have DSD capability that nowadays even a low cost external usb dac has. So if you are not concerned with the asynchronous input, go with the CXA60.
I was impressed with the Yamaha A-S series integrated amps, until I search and found some bench test results on the older A-S500, 2000, and 3000. Their test results seemed worse than their AVR's, I had to re-read them a few times as I found that hard to believe.
2. Based on historic test results I have seen, the NAD ones are better, but you can stretch a little beyond $1,000 then the Anthem 225 is hard to beat.

Specs and test data aside, and subjectively, integrated and separates are definitely more attractive if they offer all of the features you need. Objectively, based on specs and bench test data, the higher mid range AVRs do offer better value due to economy of scale. Talking from experience, I am 100% sure most people would fail a simple blind (no need to be double blinded) tests on the integrated amps you mentioned so far, and the results will be the same if you add a $1000 (less if on sale) AVR to the mix.
As often cited on this forum, if you want better sound quality, look to speakers, room acoustics, and perhaps most importantly the source media.
