Hi all I have now fitted Anthony's new nxlsp400 modules to my monoblocks and can offer the following impressions. The new modules are fitted to the same monoblocks as the NX400NP synergy modules nothing has been changed except the modules to make the comparison as accurate as possible.
Ok first impressions are that these new modules are a little faster sounding, the bass control is about the same as the synergy (excellent) the width and depth of the soundstage is excellent and the imaging is superb. Perhaps a little better than the synergy as I've now been able to move my speakers further apart without affecting the centre image and soundstage. They are ruthless in their presentation, but this is not to say they are harsh they just reveal exactly what is on the recording so put rubbish in and you will get rubbish out. These modules must be used with good quality source components and speakers as they will quickly show up any weakness in your system, on the other hand if your other audio components are up to it I doubt you will find a more transparent and accurate amp
