Well contrary to my original scepticism, mainly caused by this idea of " signal grounding" which I find more than questionable for reasons already stated, I can now happily report that these things work. I was simply too impatient. They need much time to settle in. There was not much change in the soundstage, probably because this is one element the Lamms are truly exceptional in, but there was a definite improvement in one of the for me most important aspects of music reproduction: Bloom and air around instruments! I truly hope, returning from a live event and sitting in front of my rig, it will drive me a tad less up the wall from now on or wanting to smash it all up. The life of this music lover and -alas- also audiophile has become a little less hard. That said, i think I'll give the Poseidons a try.
Good to hear the Entreq has settled in and have to admire how you stuck with it and are now getting the benefits. Mike AD
