Not sure what to think or do...

A few months ago, a 4 month old Parasound JC5 exploded and took out a speaker.  They were pair of JBL towers and they sounded fantastic with the JC5.  Parasound warranty replaced the amp with a new open box after determining I was not at fault.  Speakers were long out of warranty so I ended up taking the loss and purchasing new speakers.  I got a new set of Wharfdale Elysian 2.  They look great but everything sounds terrible with the new speakers and the new JC5.  Both the new amp and speakers have about 30 hours on them.  I dont think it is the speakers because I tried with a 8 year old A23 Parasound amp and they seems to sound a little better.  So either things havent broken/burned in yet or I just got some bad equipment.  I hear people tell me it takes 100s of hours, etc, but Im worried and dont expect that big of a change over time.  This has been a bad experience for me and I feel like giving up on the audio hobby.  $6k on speakers, $6k on an amp yet the acoustic panels on my Sony tv also sound just as good so Im confused.
