QLN Prestige 3

I forgot to add, the bass on the X2's is far more dynamic, fast, present than I would ever expect for such a small speaker. Anything positive you hear about bass on these X models I think you can take it as true. I am waiting on REL S510's to pair with it...

OP is your room treated? I’ve found that when you find a speaker fatiguing, it’s not always the speaker. Sometimes more detailed speakers are simply shining a light on your room deficiencies. If your room is well treated, feel free to ignore my post :)

QLN and fatiguing in the same sentence, this is a first. Would agree on the room treatments. Synergy is key and the Boulder may not be a good fit (I am shocked) 

I will have to give Borreson another chance, in a better setting, and with my music. 

I have 5 Stillpoint Aperture 2’s and a few bass traps.
