scala 寫:I am not a professional in writing article about sound performance. I just use layman term in explaining my feeling. I believer the sound from Class D amplifier is able to reflect the source directly. It is very powerful due to high power conversion efficiency. When I turn the volume high up to -5db, it still have enough power to produce the bass response and also maintain the small ship cracking sound when I watch U571. The sound stage is also great, I feel I am inside the Albert Hall when I listen Robbie William concert.
scala 寫:I found many of you is very interested to the cost. All I could tell is the total cost of raw material is not less than 20k. But this cost is not included my labor and those tools used for assemble. Since the professional tools is very expensive, I am glad that some of my friends share their technic and tools to me in making this amp.

You meant over 20K ? That's not cheap for a DIY amp.

scala, you have used a lot of expensive capacitors and resistors?

But looking at the pictures, I don't think that's the case. (Infact quite average parts )
