I had MF M6i (before built-in phono stage si model) and Revel F32 speakers sounded great with it. Also, if using the built-in DAC, I suggest buying a stand alone DAC. Built-in DAC is weak link and Ayre QB-9 sounded amazing with my MF M6i. IMO, Musical Fidelity is very good. M series much better than A series (M series replaced) and more w/ch achieve better sound with MF gear. If I did not swap SS for tubes, I probably would still have the MF M6i.
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")
