I would like to know if any one of you evaluated the ES7100 and ES9000 side by side. I am considering purchasing one or the other but not sure if the 9000 is worth the extra $1200 (best price I found on the web was $2300). The 9000 was released at the end of 2004 so does the 7100 has more advanced or newer technology? I appreciate your feedback.

You can read Sony's white paper here........

In therory at least the 7100 should ou perform the 9000 sonically. In actual practice that may not be the case.
A review in the The Absolute Sound magazine the reviewer thought the 7100 was at least the equal to the 9000 in sound quality terms. That review can be read here......

I was reading over on the Oade Bros website that the iLink interface on the DA7100ES was so accurate that it measured .08 Femtoseconds of jitter! That is the same amount of time that it takes light to traverse 80 Sodium atoms!
If you plan on using iLink this would be an important consideration.

Thank you so much for your feedback. I am still curious what makes the ES9000 twice as expensive as the ES7100. If you have any additional information I would appreciate you sharing it.

Generally the first production run of a new high tech product is the most expensive. Manufacturers of mass market products then start to look for ways to achieve the same performance by using less expensive parts.
The 7100 has a different power supply than the 9000 for a start.
Eventually the economies of scale takes place. The larger the number of a particular a part is made, the less it costs to make. Computer processors would be a good example.
I have not seen the 7100 in the flesh but I have seen the 9000. As awesome as the 7100 is I suspect that it's not quite built to the same standards as the 9000.
The 7100 is made in Malaysia. If the 9000 was built in Japan that would certainly contribute also. 9000ES owners, where is your receiver built??

GabeT- The sound of either the DA9000ES or DA7100ES will be greatly influenced by the Digital front end and speakers that you use with it. What plans do you have in regards to outfitting your new Sony Digital Receiver?

When it was first available in October of 2003 (date of service manual first release), the STR-DA9000ES was (and still is IMO) the best build of the new line of digital receivers. If you were to compare it inside and out with the STR-DA5000ES or STR-DA7100ES, this would be immediately obvious. The output transistors and heat sinks are far more rugged, as is the toroidal power supply. There is also increased I/O flexibility. Granted, it doesn't have some of the features now available in the STR-DA7100ES, but you should expect that since the STR-DA7100ES is nearly two years newer (June, 2005, service manual first release). In that two year period, several major problems with the digital line were identified and corrected. The S-Master process was improved (higher resolution).
I would expect the STR-DA7000ES build to be slightly above that of the STR-DA5000ES but still noticeably lower than that of the STR-DA9000ES.
