I just ordered a Barefaced Big Twin II and was wondering which Class D amp I should pair it up with. I do currently have a TH500 but am looking for a backup or to have the TH500 as a backup. The Barefaced Club has many pages and plenty people commenting daily so feel free to comment here and help me with this decision, please. Aguilar is also coming out in April with the AG700 that I can't wait to hear. I have listed most of the amps that I found to be in the $1,000.00 and under range which is about where I would want to stay. I am also open for suggestions of some that I may have left off. Thanks in advance for all of your comments and choices.
