No binding post/ Amp hardwired to speaker wire. Anyone tried it

I had my Eichmann binding post break and was in the market for new post. I have cardas on other amps but always thought all that copper has to effect sonic. I have a pair of speakers hard wired to external crossover with good results. So instead of ordering new post and waiting for them, I opened up amp and hard wired straight into amp. I was hoping for improvement but did not expect such a improved sound. Much bigger improvement than going direct into crossover. With this system the speakers are connected to crossovers with spades. I hear much more in the music or recording, things fade in and out more subtle and natural. Like you can hear how the guy in recording booth mastered the recording.
