I haven't heard the 871 but heard the 861 and I thought is very similar in sound on SACD, but I vote for the 301 on Redbook. I guess it would come down to, do you need the DVD-DVD/A or you after the Sacd/Redbook for playback. Either piece will justify the means whether you are looking for multi use or just two channel. In My opinion of course. McIntosh makes some great stuff.
