Please talk me out of buying the Avalon Eclipse

I am not sure about "most" but I can sure buy into optimism these days :)

$700 is really enticing.  If you have older Rowland or good tube gear it probably would be worth it--I would not drive them with Class D or a cheap amplifier.  The soundstaging of the Avalons is remarkable, and the original models were superbly built.

Well, I am still using my Eclipses I bought 33 years ago.  Still work fine, and still enjoy them.

Very inefficient: I have each of them biwired to a MC275 mk5.  You need a lot of power.

Yes, the bass can be a bit shy.  Using Anticables improved that significantly.  Currently I am in Mexico helping a friend get cancer treatment, so I cannot look at which flavor I have.  But you need one of the higher versions of AntiCables for the woofers.

Also I heard them with subwoofers.  Bass issues go away with the right ones.

If you can audition them to see that they are working fine, then you get an awful lot of speaker for $700.  From the comments, sorry to see that Avalon isn't the company it used to be.  Sounds like you need to make sure that they work before you buy them.

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?

@jmkrajnik so sorry about your friend. Wishing him/her smooth treatment. Thank you for taking time to respond.
