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

Regarding dual mono amplification, I remember noticing a significant improvement with my Naim Audio system, when switching from a Naim NAP 250 to a pair of NAP 135 monoblocks.The same sound signature, but better control over my speakers (Harbeth HLP3ES). Greater width, depth of the soundstage, better instrument separation etc. System at the time was a Naim CDI, 72/Hicap/NAP 135/Harbeth HLP3ES. If a dual mono design is properly implemented in an integrated amplifier then it seems logical that it would sound better than with a single power transformer. Just some grist for the mill. 😄

my father in law has a hint 6 driving some LS50’s which I will listen to soon. I do prefer a simplified integrated since I have an external Dac and streamer.

this is what I’m getting at. I have a pass integrated which is great. The separates beat it at soundstage dimensions. Tone is another question as the Pass is glorious.

In that case(!), to find out the best practice for dual mono-ism in that form factor/price range, just lift the cover on your integrated. I have full faith in Nelson Pass.
