Onkyo make solid and very good 2 channel kit. I've not heard the model you mention but Dad uses a lower range Onkyo CD player and it is excellent. My only real concern is whether it is actually worth paying all that extra for the higher range models these days. Perhaps better to buy a decent entry level disc spinner and an external DAC that will give you more flexibility if/when you explore streaming.
SACD is niche. It is still reasonably healthy in the classical world but releases are few and far between in rock/pop music and I've generally found SACD drives are noisier than standard red book drives.
