wouldnt directly know but had a lot of sony amps over the last 30 yrs, enough to notice the drop in build quality of the es products. my hunch (educated) is that the sony isnt even in the same league as the nak. no experience of digital amps but know enough to trust nelson pass over the computer boffins. would strongly recommend you forget the "surround" idea if you are a music lover.if you can afford to retire nakki then suggest you look at a passlabs x150 http://www.passlabs.com/amplifiers/x150.htm ps, i'll buy nakki if you want her to have a nice cosy home n some new cappies..... kind regards, ian
Sony STR-DA9000ES -- how good an amplifier?
It looks like the Sony STR-DA9000ES is available from a number of reputable sources for a bargain price ($2300 when it lists for $4500). Is Sony replacing this model?
Also, it's rated for 200wpc and apparently uses class-D digital amplification that I'm not familiar with. However there's a recent, very positive review in The Perfect Vision.
Here's the question: I don't currently have a surround system (it's in progress) but just bought a pair of B&W Nautilus 801's for the fronts. I'm curious: is there any hope of driving these speakers with this amp? My current amp (Nakamichi PA7, also 200wpc but a reasonably good current source) is pretty long in the tooth but actually does a decent job (the speakers aren't even broken in yet but sound wonderful). Is "digital amplification" just out of the question here? Since I don't have surrounds yet, does it make sense to use four channels of this 7 channel beast to biamp the 801s or is the power supply the limiting factor?
I guess the alternative is one of the multichannel Parasound/Adcom/B&K amps but I really like the feature set of the Sony STR-DA9000ES (DVI switching!) at this price. I just want to know if I'm way off base by considering it.
