Ludimagis is correct about the diferences, but I have one AA capitole mk2, I did not make the upgrade to SE version yet, but I listened to AA reference for some days and the AA capiloe mk2 was better in all aspect, besides has 2 or 3 kgs more, I listened with two friends the two AA, and all of us noted the diference , The AA capitole mk2 is fenomenal,I ask abou this diference to the AA seller and he said that after a period of burn the reference will be better, I did no understand this because the AAs were news , and if depend of burning the AA cmk2 was getting better too. All I can say is that AA capitole is the best cd player I listened, pristine and clear.
