Matts - I have only the original iron in the Paramours, which I run on 4 ohms which providers a slightly 'tighter' sound, but with reduced output and slight loss of 'air' about the sound overall. I will be considering the MagneQuest iron later as an upgrade option, when funds become available.The bass is almost sorted now after bringing in some room treatment - just a few more changes to make. So now my focus is moving toward the treble which I'm finding a bit hard edged - still low hours yet, but as the bass gets better the treble seems to worsen.
