I want to preface by saying that I’m quite happy with the Merlin’s, just looking for a change of pace. Love the midrange and soundstage provided by the TSM’s and I’m looking for something similar, but with just a bit more dynamics. I like that the M4’s are acoustic suspension like the Merlins as room constraints dictate close proximity to front wall. These will be augmented by a pair of REL T5X and driven by an Anthem STR integrated amp (yah, I know the whole Merlin and tubes argument). I’ll also add that I don’t have the ability to go and audition various speakers, I’m restricted to buying online, and preferably from a vendor that offers returns.
