Hi David. You're probably not going to read this, but in case you do, why did you downgrade your rating for this processor, the 5100, over the 5000, which you gave a perfect five stars? (In audio performance) What changed in your opinion? You seem less impressed with its two channel performance, over the previous model as well....why is that?

i have a yamaha cx-a5100 but have only the space for a 5.1 system. so in my room it's impossible to mount height speakers or upwards speakers on my excisting speakers. can i simulate the presence of height speakers( which i have not) with dts neural-x which the cxa51100 has ?
kind regards,
frans callebaut
