everything sounded great until the upgrade


In short: I loved the sound of my modest system, until I upgraded my amp. Now it  sounds pretty horrible. It went from a warm sweet embracing easy-to-listen sound to knives and forks trying to escape from a bathtub.

So...

1. I can just unplug this new amp (used) and sell it

Any other options? I could upgrade my speakers but I have no budget for that.

2. I could sell the speakers and use money to buy used ones that go with the amp. 

3. Lastly I could change the source, but was it the culprit - to begin with?

btw - the sound of the "new" amp is decent with my turntable, and terrible with my CD player.

(If I wrote brands and models it would throw the discussion into "A sucks, B is great")

The caps are dry there are sitting in jamicon caps, Chinese grap.

Take them out and put mundorf i did it last month and you dont know whats happend.

For shure that it is the problem the caps are super dry if you shake the amp maybe you can hear it.

@grislybutter    Why didn't you try the amp in your system before laying down your bread?

It's incredible how many people here buy upgrades without listening to them.  It's little use listening at the dealer in his system unless he can replicate yours or you take your kit in and set it up.  Even then the rooms are different.

No dealer of any worth will refuse to lend equipment to loyal customers.
