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


+1 for the i-30. liked it better than the Kinki. I’ve moved on to a much more expensive dual mono integrated from Audia Flight but the Primare has to be one of the best amps for the money on the used market.

Thanks for the i-30 recommendation. It may allow for experimentation without breaking the bank. Those are some beefy transformers...
