Although I liked the AVP-9080, it really showed it's shortcomings once I got the Sony TA-E9000ES. The Sony was more detailed and open, with much more flexibility than the Newcastle as far as setting crossover frequencies and delay settings. As far as DSP modes goes, the Sony has almost too many choices. Like many others, I don't care about church, hall, stadium modes because most manufacturers do them so poorly. The Cinema EX modes and Virtual 6.1 of the Sony were my favorites depending on the movie being played. As I recall, the Newcastle had less options, but was also less configurable.
I tried a Lexicon MC-1 recently and it outperformed the Sony significantly, but not as dramatically as the Sony over the Newcastle. Specifically, the Lex had better channel steering and gave a more
being there presentation which I preferred. Everyone in the family noticed except my wife... ole stone ears.
The other thing that the Newcastle lacked was auto-DTS recognition. I got tired of having to switch to DTS on the pre-amp when playing a DTS soundtrack - and you couldn't do it from the remote. For music, the Sony is much better as well. In 2-ch mode, the TA-E9000ES is invisible, but exhibits a slight hiss in multi-ch.
I just ordered my 990 tonight. I hope it is as quiet as I've read. I'm looking forward to moving up to 7-ch and lowering my noise floor even futher.
Not owning the 990 myself yet, I hesitate to give advice. With that disclaimer in place, I not be the least bit surprised that the 990 would be a significant upgrade over the Newcastle. Pull the trigger. I did!
