Hi Everyone

I have been reading this forum for some time. It's great to see so many nice people in our hobby!
I have been listening to Quad ESL 57 for many years now. I don't think I will part with them any time soon but I am thinking of getting a new set of speakers. I love the musical tonality of the Quads and I want to get more dynamics, energy, maybe more air and soundstage. I might be wrong but I think that open baffle speakers sound closer to the Quads than boxed speakers. In my quest, I went to a local dealer and I did not like the sound in any of their very expensive rooms. It was hard to tell if it was an electronic piano or not! They had mostly BW and KEF. I heard Caladans on a show and I thought they were a touch sharp for my taste. I realize that all that could be due to other equipment, source, room, and many other factors. However, I am sensitive for the sharpness in HF. I don't have an opportunity to listen to any of the GR speakers and to be honest, I think they will sound different in my setup anyways. I listen mostly to classical music and Jazz. Most of my stack is tube. I listen mostly to CD and SACD (I love my Sony SCD-1) and sometimes vinyl and DAC.
Long story short, I would like to build GR Research speakers. My room is pretty small 13x17 with windows and a french door. I do use quite a bit of acoustic treatment. I have been thinking of NX-Otica or X-Static but I am afraid they might be too big for my room. I am open to other options. Can I please ask for your advice.
