Currently, I am running a 105 BR player through my Onkyo Processor to feed my 1080 Plasma, using audio leads for stereo/multichannel and HDMI for movies. But I am intending over the next few months to update to a 4K system. Currently, I am considering either a Marantz Processor or an Arcam 390 feeding my P7 amp. Both of these systems have good onboard DACS etc. I am also in my mid-50s and starting to have a hearing deficiency due to old age. I can still appreciate a good sound though, or at least my interpretation of a good sound!1 So would the extra cost of the 205 be worthwhile, or would Ibe better off buying the 203 and connecting that to my new AV amp/processor to do the decoding for me? I am thinking that I may be better saving my pennies and buy the 203 and perhaps buy the Arcam 390 instead (after auditioning of course) I hope this makes sense?
