I auditioned a Opera Consonance C-100 solid state integrated amp in 2006 in a local stereo shop. Its smooth, full bodied and robust sound really made a permanent impression on me. I've always disliked the hyper-detailed sound and and lean towards a more relaxed sound. Well finally made a purchase and a mint C-100 w/ original packing will arrive at my doorstep shortly. I hope the C-100's 180 wpc @ 4 ohms delivers the sound I remember for my Seas Froy mk3 4 ohm speakers. Information on the Consonance C-100 it is minimal, but digging deep my research reveals it is basically a Hegel H-100 amp w/o the usb dac, digital display, and HT bypass. The similarity in looks and chassis is also compelling. Reviews of the Hegel H-100 remind me of what I remember hearing from the the C-100 years ago, which made such an impression on me. For the last 1-1/2 years I had a nice HT system, but couldn't wait to sell it and return to a smooth and inviting 2 channel audio for my aging ears. I can hardly wait for it to arrive and will keep you posted.
