Emotiva amp
I haven't seen any measurements posted for the LPA-1, but the specs on their other amps have been accurate.
My LPA-1 has no problem driving my 4 ohm Onix Ref speakers with 2 amp channels powering my distributed house audio system. The amp barely gets warm, unlike my Yamaha receiver.
There are coming out with a couple new models including an LPA-2 (w/ 7 channels) and a 200 Watt x 5 XPA-5 amp.
