i currently have a pico dac/amp and have hd800 on preorder. My concern is that the pico as an amp will not be able to fully power the hd800. I know the benchmark will probably have a better dac; but will the built in headphone amp be an improvement over the pico as an amp? I know many praise the dac on the benchmarks but feel the amp is not up to standards for phones like the hd650 and probably hd800. Can anyone comment. thanks
the hpa2 manages to drive my k1000's relatively well, on the cusp, delivering 7.5 watts at the k1ks 120ohms, i also went one step further and removed the relevant jumpers in the benchmark to have higher gain on the headphone stage (ie, no minus db figure present) dependant on what dac1 version you have the options may not be as good as the pre for gain settings
in other words, if it can drive my k1000s, it can drive the hd-800!
besides, thats the dac/amp sennheiser were demoing the 800s with at one showing
