john07,
I just did a Google search for the Sunfire TG III. There was a review on audioholics.com.
Read the review and make your own conclusion.
Basically they did mention the Sherbourn and Outlaw 950 (shared platform and the Outlaw unit is discontinued ….mmm) as equal or slightly better products -especially for the price. Audioholics mentioned the Denon AVR-3803 was more flexible and better performer.
I have read from other gunsliners who purchased the 990 as a replacement to the AVR-3803 that there was no comparison. Better soundstage – presentation, steering in DD and DTS, etc.
I myself jumped from a Denon AVR-3300.
I have not heard the Sunfire TG III – but from hanging around in this forum – I would be surprised if you would be disappointed w/ the 990.
Good luck, keep us informed of your decision and welcome to the forum.
