BLK25 I am not sure that is fair. I am not an out and out Naim lover, but as I understand their philosophy, it includes giving a clear upgrade path, to help purchasers. You start at a given level and can add to it incrementally without losing your initial investment.
Secondly, as I understand it, they believe power supllies should be separated from the music part of the equipment, for sound quality reasons. This means power suppies are in a separate box. Rather than forcing you to buy the power supply with the origonal kit, there is a basic supply in it, to get you started. That seems to make sense to me.
To answer the origonal questions, it is axiomatic that upgraded power supplies always make a big difference with Naim, amp, pre or CD player
