I fully understand. It seems YPAO in lower end models were of a different level quality wise. But I hear from others that 5200 has 64 bit R.S.C which does a good job till 30HZ though personally I haven't tried because GLM takes me to a different level. However I need to admit, that DIRAC via miniDSP for my SVS subs does an excellent job.
On the other hand the ESS Sabre Pro DAC in 5200 along with the XLR feeding Genelecs has converted my living room to a place better than the nearby cinema hall
. Earlier I used to have Yamaha RX-V775 - a lower end non-aventage model. The CX-A5200 (especially with XLR connections) takes me to a different planet sound wise - instrument separation being the highlight.
