I have paid a visit to a HiFi Shop located at Tim Chi Building (Mongkok). As you said, they offered the mentioned power supply at HK$9000 including delivery fee.
In view of the cost, it seems that it is more worth to buy it in HK as the value of RMB is increased. However, I am still doubtful is it worth to pay 9k for this improvement. (I mean the improvement is significant or just a little bit?) Also, the price of this range (9k) is available for me to choose another band names just like Silver ribbon, CSE and Isotek ect…. Is Dussun can give a great improvement compare to other band names? I would like to seek your further comment, pls.
Thank for your detail reply.
I really want to find a power station with filter for my Power amp EDGE NL12 and also the digital parts (Pass Lab alpha pre amp and Cambridge Audio 640C CDP). For the part of power supply, I am now using a cheap product made by RPC.
In fact, EDGE is a power demanding device. (300W per each channel) It seems that it would be unlikely to use Dussun to push my Gear. Is that right?
