I do not know the Levinson sound well, other than a long audition at a retail store. They were incredible driving Thiel 3.7’s with Transparent Reference cables. I was there evaluating the Thiels and the presentation all together was outstanding.
I believe the 601’s are slightly different from the more traditional Mcintosh sound which is warm, full-bodied, generous midrange, sweet top end, plenty of detail but not the last word in resolution. I prefer that presentation with the right ancillary eq. The 601’s have a little more speed, air, and transparancy than my 501’s for example. And I have also heard the 611’s may take that even further.
