I can tell from the recording you posted that your amps and speakers are pretty solid. Everything was clear.
I heard a 1,200$ set of dynes being run off a JL HD amp passive. My system had more detail because of my deck and processor, not because of my speakers/amps.
It sounded great, but the musical detail wasn't there.
I can loan you my eclipse cd7200 and you can tell me if you see an improvement. I wouldn't charge you a dime for the loan or shipping LMK.
Anyway, not my thread to jack, you have an amp or two to sell. Good luck again!
Does my girlfriend still have this
