I know this will irk some people by my philistine approach, but bear with me   I currently have a Harmon Kardon 3480 and Celestion speakers for my main living room (apartment, not too big). Both were bought used and have given me good service, but the amount of wiring for what essentially amounts to me blasting a laptop or similar output (HDMI from television, or simply a phone playing low-bit MP3 files) is getting on my nerves. Simultaneously, the sound has "degraded"....
