#39 NAD C 658: $2,299.00 Upscale Audio eBay
Pros: It is a full streaming preamp with Ethernet, Wi-Fi, Bluetooth with aptX HD, two optical and two coaxial inputs, analog RCA inputs and an MM phono stage. Dirac Live room correction, stereo subwoofer outputs and XLR preamp outputs make it a flexible hub for a speaker system.
Cons: Audio Science Review measured only 90 dB SINAD, so sensitive in-ear monitors may reveal hiss or noise. NAD doesn’t publish a 32 ohm power figure for the headphone jack, and the SMSL M10 rates higher for far less.
