Conclusions
Forced to sum up the Rega Apollo's sound in a sentence or two, I would write: This player has a sonic brilliance—a clarity of detail and of musical line, allied with a spatially up-front presentation—that enhances musical engagement. The Apollo doesn't gladly suffer bright or timbrally threadbare CDs—something I dimly recall being even truer of the original Apollo—but with most discs I tried, it provided enjoyable, involving, nonfatiguing sound.My thoughts on value are even more concise. As with other Rega products—their entry-level tonearms come to mind—few other audio components of my experience, and no other contemporary CD players, offer so much music for so little money. Unless your system has an egregiously bright sound, you can't go wrong with the Rega Apollo. And if your heart is set on spending $10,000, go ahead and buy nine of these and spread the love. Robustly recommended.
