Hello @ghasley @thyname @lalitk @snopro @wsrrsw , Happy Holidays!!!
So somethings about my Grimm MU1. Interesting how many say it is immune to different ethernet and or power cables. Also very interesting was in the M101 room at CAF. Lubomir was demonstrating the positive effects (improvement in sound) of inserting his 1.5m ethernet cable going into the streamer or DAC. But in his demonstration, he bypassed the Grimm to show off his cable. Why? Because the mu1 uses a generic internal ethernet cable. In a sense this generic cable 'undoes' the benefits of using an expensive ethernet cable into it.
So, you are thinking, (at least I was) can we replace the internal ethernet cable in the mu1? Lubomir liked this question and was already on to it. So I sent him my unit, and he replaced the stock cable with an identical length of his ethernet cable (M101).
I received it back last night and have only listened for about an hour. But, it is astonishing! The soundstage has opened, and I can now pinpoint locations of performers even better than before. The attack and dynamics are formidable, with great bass and yet still organic and smooth. For those who said the Grimm was too laid back and polite, say that no more with this modification. The highs are uber crisp. It is though the music jumps out at you.
The Grimm MU1 is indeed a great component.
