Golden Audio Aon 3 vs Aon 2

• 
  

 The speakers are by Golen Ear Technology. having a hard time deciding between the two. Is there much difference besides the bass being lower in the 3? Would both play an acoustic upright bass solo well? I’ve heard that the 2 has a little bit better imaging. Is this accurate. 

Which one do you prefer and why? I haven’t had a chance to listen to either one but I love the reviews of both that I read. I could use a little help in deciding. Thank you very much!
