I think you may want to give that idea further thought. The 95 does not have any video features that are not in the 93. As for audio, the 93 and 95 are identical doing HDMI digital audio. Most of the people who buy the 95 have very expensive analog electronics that they do not want to replace. You aren't in that situation, so it makes sense to exchange the 95 for the 93. Based on what you've written, there is zero advantage in keeping the 95.
Given the type of speaker cables used on your Bose, you may not be able to easily use the Bose speakers with a new AVR. From what I could see in the V20 manual, the speaker wire seemed to have some type of Bose terminator on each end.
Tip: For HDMI cables check out "monoprice" which is linked at the top of each page here at AVS. Go with their 28 AWG high speed HDMI cables like those listed at the link below. Monster cables provide nothing extre to justify their price.
