If you had to narrow your choices to 4 - 5 speakers

The OP asked for recommendations of speakers he can listen to at Axpona. Many of the suggestions aren’t going to be at Axpona. Here’s a link to a list of Axpona exhibitors: https://axpona.com/exhibitors/

Listen to the RAAL SR1b with the VM-1a amp at the show (headphones that sound like 2-channel). Then compare that to million-dollar 2-channel systems at the show. Hopefully, RAAL will have a VM-1a to demo. They seem to sellout each batch.

Throw the solid state amp in the trash(ebay) Get a carver crimson or raven.  And a pair of cliptch lescalda. Enjoy 😉. 

Thanks again for all the suggestions but @smatsui is correct I'm looking to hear speakers at Axpona and usually buy new, just a personal preference.
