I am trying to make a decision between the 2 of these receivers, however, I find it quite difficult in deciding which way to go. I may be able to still get my hands on either of these within the next few days, so I need some down to earth advice as soon as possible. Sony DA4es suggested list price in Canada: $1499.00 DA5es lists for $1599.00 However, I know that I would be able to negotiate a better price with cash purchase etc. Someone told me that I may be able to get the Da4es for about $1000-$1100 canadian. The DA5es for about $1200-$1250...inclusive of all taxes. I have read a lot of difference of opinions about these 2 receivers etc. Humming from the 4es and so forth. 5es unable to play certain DVD's properly without a firmware update etc. I have already downloaded the firmware update, just to be prepared. Well, experts, what is your opinion(s) Thanks in advance for your input to this topic.
