Marantz vs Marantz

This is a big forum with lots of members and the chances of someone having an answer that can be useful is therefore high and this one is regarding Marantz PM-11S3 (integrated) vs Marantz SM-11S1 (power amplifier). According to Marantz themselves, these two amps are complimentary to one another and use very similar approaches. Both use the HDAM SA3 as an example, deliver pretty much the same power and so forth.

But I still want to ask if someone has dealt with both and can inform me of if there are any discernible difference in the in the performance arena that I should be aware of ?

I have the SM's and there are differences to be found in the HDAM-SA3 between them. If it matters or have a significant impact is difficult to judge by only staring at the paper... Unless the components being used can be use as an argument..
