If it’s a particularly good price compared to other comparable designs and they are in good condition why not?
Disclaimer: Heard Avalons once. Similar size and look but do not know what model. Liked them but found the sound quite unique. A lean sound for the size with a very expressive upper midrange as I recall. Were it me I would want to hear before buying. Proper gear matching may be key. I’d be less concerned if DSP were in my toolbox
Did that do the trick?
