Problems resolved: Learned alot: The dealer loaned me the MF integrated A5 amp they had in the showroom to try at home- what a world of difference! I have the sound that first brought me to the A5. The sound opened up, the fog lifted and the bass notes rather than rumbling became actual notes. The music is much more compelling, something I could not say playing it through the rotel set up. I paid a price for the lesson of thinking I could mix and match without researching first. I will keep both systems side by side, since I like having the rotel changer (I know, shame on me!) for when I need continuous party or dinner music and reserve using the MF for blissfull critical listening. thx for all the observations,and advice from this generous group.
