Classe ssp-75 vs classe ssp-300 2ch battle

I want to know who has heard a ssp-75 and ssp-300 in 2ch mode which is more musical . I have a ssp-75 I find very musical I just upgraded my amplifier to a classe seven hundred s700 from a mca 3 . Classe s700 is balance connections. I know the ssp-300 is non balance . Who has heard these or any comparisons. Thx using 4 ohm lsi15
