I must say, I have thoroughly enjoyed my Energy Reference Connoisseur Series-based system for over ten years now. Very nice dynamic sound quality for, both, music and movie/TV soundtracks. Most everyone who happens to hear music on my system always comment how nice and clean it sounds- all types of music. Have provided a lot of enjoyment for the cost.
These were the original release Reference Connoisseur Series product (circa- 2006), manufactured in China. The overall quality of the design and fabrication of the Reference Connoisseur product was very good, and has proven itself over a significant span of time. The driver components all look good- the rubber surround materials have maintained very well. The cherry veneer wood cabinet finishes all still look like-new, beautiful. As well as the materials used on the front grills.
I've yet to experience any "show-stopper" failure on these speakers. The only "noticeable" issue so far is the blue light auto-ON/OFF indicator has stopped functioning on the S8.3 subwoofer unit (which, apparently, has been a well-known problem or frailty). While this does'nt effect the operation of the sub, I wish I could get this part replaced. I love the blue light (although many did'nt really care for it
These speakers have been part of maybe three different systems, powered by various receivers and amplifiers (including- NAD C272 amp (150W per/chan); Yamaha RXV-1600 & RXV-2700 receiver's (120W per/chan & 140W per/chan respectively); Parasound A51 amp (250W per/chan). Have performed very well.
