buy the best amp you can find like the cary 805 or air tight 211 and see if they work with your speakers. If not, get rid of your speakers, they are broken. the amp is king.
Which amp matches best my JM Lab Mezzo Utopia ?
I have clearly a predisposition to single ended and Class A design. Push pull does not apply. The speakers are a demanding load though. They go down to 3.8 ohms.
