I have owned the Motion 60XT for two years now and wanted to let the folks at Martin Logan, and everyone researching this excellent speaker, just how happy I am with it. My system is solely a 2-channel audio system. I have a Rogue Audio RP-5 pre-amp, Marantz SA-11S3 SACD player and ADCOM GFA550 power amp. While the other components each bring high level of sonics to the system, adding the Martin Logans to the mix was the biggest transformation in sound improvement without a doubt. The sound quality is superb. Yes, all the bases are covered-soundstage, clarity, timbre, dynamics, and so on. Most importantly, there is a real musicality and a sense of 'being there'. On superbly recorded/engineered recordings the sound is breathtaking. I have the SACD version of Dave Brubeck's Time Out. Each time I play it I just smile. You'd swear they were playing there in my living room. Piano, sax, upright bass, drums all reproduced expertly. I recommend anyone interested in the Motion 60XTs to read David Martson's review of it from 2016 for the Absolute Sound which is here on this website. Again, I wish to thank the everyone at Martin Logan for designing and producing such an excellent speaker, one that makes it possible for more of us to enjoy what high-end music reproduction is all about. One final note, the quality and craftsmanship is outstanding, including excellent speaker terminations. Happy listening!
