[QUOTE="pwatts, post: 752332, member: 146"] Very interesting feedback from a technology perspective. Audiomat seems to focus on using exotic components, using Clarity caps even for PSU bypassing, and a discrete output stage. Otherwise there is polymer electrolytics, Dale resistors and zero surface mount parts. A bit of image searching to find the PCB bottom showed the Audiomat 2.7 using PCM1794A indeed, not even in dual-mono and without any proper power supply decoupling. PCM1794A is one of those DAC's that is easy to get to sound reasonably good, but for truly exceptional results it takes a lot of skill, experimentation and some luck. ESS DAC's on the other hand, despite the high cost and excellent measurements can sound downright meh if implemented without proper care. There is a new version out, the ES9028 (and 9038), but the differences are not expected to be night and day. Got a sample on the way to evaluate in a test board. The new AKM DAC's are the exciting bit. Reports have it that they go as good as Delta-Sigma allows and with less need for elaborate surrounding design. [/QUOTE]
