We have now had the opportunity of carrying out extensive listening test with your NXV202ps modules and pleased to say this performs extremely well on a wide range of different genre of music, but seems to be quite ruthless in sorting out the poor recordings from good ones. We felt that the bass was particularly well presented and is well extended. The mid and high range is equally good with excellent clarity and detail.
Female voices show no hint of sibilance and the dead quiet background is impressive - even though the module was bread boarded with no special attention given to the layout of the connecting or signal wires.
We compared this to a Parasound 300W/ channel class A power amp and would say the NXV202ps is certainly up there
and in certain areas exceeds the performance of this behemoth.
The other comparison was conducted vs our Glowmaster KT88 65W /ch class A power amp ( which has a 5 globes rating from Hi Fi World) and can honestly say there is very little to chose between them apart from a slightly warmer sound from the valve amp, but with a more extended bass from the NXV202ps . ( We used a 500VA transformer). This result is more or less what we expected. So there is little to chose between a "£600" NXV202ps based power amp and a £2500 Glowmaster KT88.
We would certainly agree with some of your other users who have posted reviews that these offer Krell / Bryston performance - but at a fraction of the price
