I had a similar experience when I bought my Revel Ultima Salon 2’s. I used a 5 channel Sunfire Cinema Grand Signature series (425 wpc high current) amp. I bi-amp them with excellent results.
I own 4 of these amps and I would consider parting with one of them. Mine are in exceptional condition so I would need a couple of bucks more then $1500 but we could probably work something out.
