Quote:   I couldt agree more on that. In my experience the DAC chip is not really a big deal. The secret is output stage. You can have the most technically advanced chips, like sabre32 and it will perform badly. So guys look up to a good output stage....  

Today I build a very simple (lm1086) linear stabilized power supply and finally the a little bit for my taste aggressive sound signature changed to more relaxed more analogue like but whit good detail signature and dynamics. I also noticed the black background is little big darker. So I...

I received my unit yesterday so until its running and first listening moments had been very revealing in playing classical music. This is the genre where the unit was wonderful. It adds a black background that I missed in digital reproduction. I also noticed some glare as posted by...

I agree whit you CURRAWONG!   Kingwa knows what he is talking about!   Jenkys, you should learn from the past. I read your post on diyaudio forum! I really admire your work whit hiface but please you need to be more open to other solutions that maybe play better or worse.   I know...

Hi guys,   I am one of the testers. Kingwa told me he is trying to put real 75ohm BNC sockets on the converter. The manufacturer has declared that the sockets Kingwa uses are 75ohm but he does not think so. The same are on hi-face so they should be also not true 75ohm sockets!!! The...

Thank you all. The information available online is amazing. I will need some time for studying. Riding all this and one question is always present: What does sound better a SE or PP design for headphones?

Thank you all for the suggestions about the literature.

I am setting this thread for all of us who wants to learn the principles of tubes, how they work in different designs and so on. how to calculate and planing the designs. how to work whit them - safety more and more questions should be asked. I WANT PEOPLE THAT HAVE GREAT...

If we still want to make a group diy project, please make a list of specifications.
