I listened to the Apollo in a showroom with a Rega Brio 3 int. amp., Rega R3's, and Chord Company interconnects and speaker cable and it sounded amazing. I just heard it again today because I am considering switching out my speakers for new ones and I was once again equally impressed. The last time I listened to the Apollo, they did an Apollo vs. Naim CD player (I think the least expensive Naim CD player, but still more than the Apollo) comparison and I actually liked the Apollo much better. I do not know if it had something to do with synergy, but it sounded stunning. I am going to get the Apollo as soon as I can afford it.
