Lalitk- you don’t know what you are talking about. I would take ps audio equipment over most of what you own.
If you want the true sound, get it at the source, before the recording. The amps that rock/blues/jazz groups use for example are fairly cheap, like the Fender tube amps or Marshall amps.
If you ever wish to recreate the sound of a rock/blies/jazz concert, it would cost much to get the exact amps and speakers that the band uses.
