I am assuming that his slightly lower efficiency speakers such as the Jazz Modules (92 dB, $4500) are not efficient enough.
That would depend on the size of the room and how loud the OP listens. I have a small room, listen to the same type of music as the OP (sans the opera), and at levels that don't exceed 90 SPL very often. I have an 8 watt SET amp that drives the Jazz Module nicely and auditioned a 10 watt solid state amp that had no problem driving them either. So a 13 watt EAR, which will play more like 8 or 9 watts with the 12 ohm Jazz Module should do fine. IMO, I think Duke understates the efficiency of his speakers. I much prefer the Jazz Module to the Planetarium series too, but that's just me.
The Tonian Lab speakers are phenomenal as well. I have the TL-D1 ($2500 these days) which is pretty much an entry level model. I can only imagine how good the upper end models sound. They do produce a lot of detail though and are extremely transparent. Not everyone's cup of tea in that respect. I doubt Tony or his speakers will be at RMAF. However, I did ask him once about a home audition and he offered 7 days with only shipping charges as my risk. If you contact Duke at Audiokinesis he will work with you as well to see if he can get you a home audition. He personally drove two pairs of speakers to my home and allowed me to listen to them before buying.
