Apex Pinnacle Headphone Amplifier and Preamplifier

John Crossett has posted a review of the Apex Pinnacle headphone amplifier and preamplifier ($10,000) at The Audio Beat. His conclusions:

If you’re looking for a headphone amp that will never restrict you in both your choice of headphones and connections while making the music you love come alive, then the Apex Pinnacle is made for you. Buying the Pinnacle because it's a great headphone amp or a great preamp would not be an act of spending money unwisely. But combine this functionality and, even at its rather hefty price, the Pinnacle represents good value.

The Apex Pinnacle is a product that not only meets but exceeds expectations — my expectations, for sure. If you have the scratch, you’ll likely not be disappointed. If you hear it, you'll likely not want to return it.
