I bought a new SONY STR VA555ES about a month ago. Then for an offer i cannot refuse, last week i bought an old demo unit DENON AVC 3800 which has been on display for a very long time but the machine works perfectly and I paired it with 3 Marantz MA6100 to drive the FL,C and FR speakers. My home theater was never been so good with this combination. Meantime the VA555ES was kept in its box. Again, 2 days ago I bought an old model DENON AVC A1 (but brand new in the box, never been used) for the same reason that i cannot refuse the offer. I am very satisfied with the performance of these 3 machines but now I must decide which one shall i retain? Any combination suggestion is most welcome. -VA555ES? -AVC 3800 with 3 marantz ma6100? -or AVC A1 with 3 marantz ma6100? I am 90% into movies 20% music. For me, the 3 machines are equal but i thought i would take into consideration any suggestion from those who have experience with these machines which one is really good before i decide what to do with the spare machines.
