Dual mono integrated amps


I’m curious about dual mono integrated amps and if they can approximate the benefits of monoblocks. I had the good fortune of trying a friend’s electronics which included a dual mono preamp driving a pair of monoblocks and the result was not subtle. There was an expanded soundstage with more solid imaging. Is this an effect that most of you experience when each channel has dedicated circuitry? Are there particular examples of integrated amps utilizing a dual mono design that do a particularly good job in this respect? Ones that don’t?

Thanks for the help

I don't think every monoblock set up benefits the same way.  Monoblocks, to my mind, benefit most from having much beefier power supplies than their stereo counter parts and/or output stages as well.  After that it's channel separation, but your mileage may vary.  I think it's possible to make stereo components with excellent channel isolation. 

Musical Fidelity makes/made several dual mono integrateds.

Some of the older models have gotten good reviews; Tri-Vista 300, A308, A5
