Avalon Isis or Sonus Faber Liliam

Hi, I am familiar with these speakers (albeit not in A/B audition). What would you like to know?
They are alike in that they both offer a competent, consistent, and pleasant musical experience and different in some ways -- not least in that the Avalons cost quite a bit more. No doubt you are aware of this.
What music do you listen to, what musical qualities are you looking for; presumably you have enough room to place them in (both take up considerable real estate) and the prerequisite amplification to drive them...

2 great speakers with 2 different sounds its up to you i like the Avalon had another model years ago and i loved them.Good luck.

Thanks for your reply.

Presently I have a pair of Avalon Isis and would like to possibly make a change to another manufacturer as I have had them for 4 years. I might be ready for a change. I have had experience with Sonus Faber and wonder if their larger speakers sound as good as the current Avalon. I mostly listen to jazz and want good mid-range with tight bass response, no boom. Sound should be natural and non- fatiguing.
