Absolutely! I have the Orion’s also - "Maggies on Steroids!"
But... the OP seemed to be asking for smaller speakers that "disappear."
And... although I love my Orion’s... they are quite a bit larger and more difficult to manage, than the LRS+ or Harbeths. And... I do believe the LRS+ does a fair job of competing with the Orions... maybe... with the exception of the dynamics and drive of the lower mids and bass and the size of the soundstage.
The LRS+ is just amazing at producing not only the accuracy and transparency of the sound, but also the imaging and soundstage, with those ESL 57 or Harbeth mids - which is all you need for "all things acoustic." If I want a bit more dynamics and drive... I’ll add some Rels to the mix of my LRS+. But for most of my jazz, blues, country and classical - I don’t miss it a bit!
And... the bonus is... the LRS+, which rivals most any other speaker - is only $1,000!
