I agree with others that have suggested playing it for a couple of weeks to let everything settle in.( Both the amp,and your ears). There is always the possibility that it just isn’t a great match for you. Sometimes we buy things that don’t work right for our tastes,and that’s when our pride or ego step in,and we demand that it works, Maybe if I replace speakers,cables,source,things will sound better. Music and good sound reproduction is a great pastime. Enjoy it,and don’t stress out about it. Worse case,flip it and try something else.
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")
