Not sure what to think or do...

The system is either wrong, as in something is out of phase, or just hosed.

If it does it sound pretty darn good, then time will not fix it.

If you think it is your home, then drag it all to another person’s house or garage and then try it there.

They look great but everything sounds terrible with the new speakers and the new JC5.

They should sound good.

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.

Yeah I hear that all the time…
But every piece of gear I have hooked up sounds pretty darn good right away.

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.

Selling it all would be an option.
If it is not the speakers, then getting some amps to demo would be wise.
But it could be that the speakers… (Dunno)

It could also be something like wires reversed, or some issue with the crossovers.

You probably need a UMIK and REW or other way to measure things.
Or an experienced shop that can help.
Or disposing of it all.

The last thing you need now is a bunch of people saying you need thousands of dollars worth or power conditioning, or power cables, or multi k$ ICs and speaker cables.

Speakers don't need hundreds of hours to reach peak performance. Do you have another pair of speakers on hand to check the Parasound amp? If there is nothing wrong it should reach optimum temperature in several hours. After that leave it on 24/7. That's what I do with my preamp/amp/DAC. I listen every day so I want the electronics running warm. 

@jasonbourne52 
Does it change much from the first time you turned it on, until a while later?

Most of my experience has shown it to be subtle, and sometimes to point of not being able to notice a difference.

What an asinine statement.

@ozzy62 - I have not heard those speakers, but assuming that if the amp is working correctly, then maybe there is some credence to Larry’s comment ?

If the OP had, or had not, heard the speakers before buying them… then it could/couldn’t be the speakers.

They sort of need to run their amp on some known speakers,
Or their speakers on a known amp… in order to detangle the mess of not knowing what is at play here.

Ideally they do this in another person’s come, so the AC cable and power conditioning crown, and room treatment brigade, do not derail the OP down another rabbit hole of cost and pate-rubbing.

Did you demo the speakers or buy them based on specs or good reviews? I you did and they sounded good on whatever amp you demoed them on, I’d look at the amp. Otherwise if you didn’t hear them before purchase, speakers, including good ones, can sound very different and perhaps you really need the sound your JBLs gave you.

No, it was solely based on video and written reviews plus the looks (which I adore). I think there is something wrong or things haven’t burnt in enough but a lower cost A23 amp which is many years old to me sounds better than the JC5 on these speakers. The JC5 is more authoritative but overall the sound on the A23 sounds better and more normal. I do not have any other good amp at the same level as a JC5 to compare.

Women wear lipstick and nice dresses, and the keeper rate is about 50%.
That is after the ones that were discarded before marriage.

I would only put looks up the list as something to avoid the haus-boss getting upset over.
(Feng Shei, and that stuff.)

It could be that the flowery prose was more figurative than literal.
