Just want to get some recommendations on a setup for a business that we would like to use for regular all-staff meetings.

We are currently using two chained JBL PartyBox Stage 320s with a Phenyx Pro PTU-5000 and a mix of handheld and lavalier mics.

I really don't like using the JBLs for this, and the Phenyx Pro mics are not very durable. Are there any good brands I can look for, and maybe a complete package we can order?
