Just got the metrum. a little background:
using a rotel 971 before getting a benchmark DAC1. i connected the output from cdplayer as well as output of benchmark to my amp so that i could switch and do A/B comparison. Sold the DAC1. the 971 dac did a better job. better in terms translating the soul of the music that one can feel more connected and enjoy the music. benchmark had more details but sounded dead. A/B comparison made me stick to rotel as the music were more involving. (when working and listening, rotel makes me want to stop and increase vol to enjoy some songs. benchmark makes me want to decrease the music as they distract)
when i got the metrum, i did the same. signal fed from cd, no upsampling etc. with rotel, i tend to skip songs that are faster and with more instruments as after awhile they sounded clustered. For metrum, i listen to them all and enjoyed the different instruments in the music. separation was improved and music remains coherent. When it comes to vocals, i couldnt stop listening to them. For metrum, many occasions i just want to sit back and enjoy the music without doing any work (you may consider this 1 weakness of metrum, makes you lazy.) when playing with my kids in the living room, i could also leave the metrum playing and dont find the music noisy.
simply said, the metrum make music feel like music, for the purpose of enjoyment...the w4s usb spif converter is on the way...wonder what will happen when 192khz files are fed to it.
love the metrum.
