I was quite surprised about what I was hearing. The rest of my system is very resolving and my ears are very picky. I had grown accustomed to the synergy between the Kharmas and the 220 tube wpc of the Wolcotts, thinking that only another megabuck amp would unseat them.
My friend, up until recently, was the North American distributor for Opera/Consonance. he brought a pair over for a listen one afternoon, and in that short time, I was intrigued, given their inexpensive (by High end audio standards) retail price tag. He told me if i was really interested he could get me a new pair at a reasonable price as he was leaving Consonance to pursue other business opportunities.
keep in mind that what I am hearing in my system with these amps includes the fact that they are cabled with products that exceed the retail price of the amps 2x, and I still have the Wolcotts. I just can't bring myself to sell them. But, I also have no immediate intention of putting them back in any time soon, as I am currently enthralled with these little 78 watt gems from China.
The bass slam, control and articulation is better with the Consonance, they don't give anything up to the Wolcotts in the mids, but the Wolcotts have the edge with respect to upper frequency extension, due no doubt to their higher power and the octet of EL34 output tubes in each amp as opposed to the quads in the Consonance.
