everything sounded great until the upgrade

I am afraid to upgrade, i dont need it, i dont want it, but i am also afraid to do it...

I already have a good synergy, for reason of S.Q./ price ratio , i cannot upgrade my 50 bucks top of the line Mission speakers nor my low cost dac marvel, then the amplifier?

I own 2 Sansui amplifier because i loved it so much...

Upgrade may be useless when you are in acoustic love.....

I am afraid to upgrade like someone afraid to lose his wife or trade her....

In spite of what most think , some minimal quality threshold being passed over by the gear, the electronical design change is less impactful on listening test than acoustic and psycho-acoustic change in the speakers/room relation...

A difference is not always or  so often than people think, a great acoustical improvement...

This is the information lacking in all audio threads...

With the empty bottle you can use a straw for the neck and experimenting with a primitive Helmholtz resonators...

I begin my first one like this...  😁😊

If you liked the sound of your modest system.....that bis all that counts.

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.
