Dual mono integrated amps

To return to the original question, have you checked out the Parasound Hint 6?  Extremely versatile, with built-in phono & DAC sections, crossovers for subwoofing, Home Theater bypass...  A bit of a kitchen sink, but a great one box solution for many pieces in building a system.  You can always upgrade section-by-section.

The dual mono power amp was designed by John Curl.  A single power transformer is used.  I suspect that is the case(!) with most integrated amps - there's just not enough space for 2 of them.

In the UK as well ATC do dual moni amps ... p1 &p2 think their integrated amps do the same

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. 
 

@jimmyblues 

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.

take a look at the Kinki EM1
