Because I was looking into what you wrote about star earthing a came across a site about building a gain clone (http://www.decdun.me.uk/gainclone_psu.html#gl3). I found a great explanation for making a rectifier bridge with MUR diodes. Because the IXYS bridge is overkill and very expensive! So...

@sapientiam. Finally I finished my first upgrades on the Lite Dac.   I did the following: 01. Swapped the R35 en R36 resistors for 154 ohm  02. Changed blue caps to Vishay (type:416) 0,1u caps (except for C38 and C39. They are still original) 03. Desoldered the opamps and put in IC feet for...

Darn, I forget about the noise again. There are several complaints about noise. People with high sensitive speakers, above 99db, say that the TDA's are quite noisy. Anyhow, it was a wild idea that just kept sticking in my head. Better to ask if it possible or just a bad idea. Conclusion, it's...

I still haven't found the time to research and read about your suggestions. All work and no play     But I'm wondering about an idea I have. Probably a wild idea. As you maybe know I already got one Lite Dac and the second one is under way. Is it possible to connect the 2 Dac's together? Make...

Saying "high end" is mostly not the same as being actually "high end":D But nice of them to send you schematics. I only use the discrete opamps of newclassD. I'm still very pleased with them. And 500 euro for a DAC! That pricey By the way, when the lite DAC runs at 6v. How high should the vref...

What you done with the snubbers does look good! You've really done quite a lot of modding on the Lite Dac. That's for sure   I shall read your post about the snubbers. Did you ever hear about the website NewClassD? They make discrete opamps and other stuff like UWB Voltages Regulators that can...

You're right about the toroidal! I will stick with the R-core.    Just one question about the bridge rectifier R2. Some people changed the rectifier to a fast/soft recovery bridge rectifier. Is this total nonsense or is this a improvement? And why only change R2 and not R1 en R3 also?   Plus...

@Sapietniam Many thanks for your answers! I must honestly say that I’m a newby.    I already did some modding on the Dac. I chanced the value of the R36/R35 resistor to 240 ohm and put in 2 opamp sockets  because I’m using 2 Dexa NewClassD discrete opamps. Plus I chanced the output caps to...

Just wondering if this thread is still alive?    I just have 2 questions about replacing the caps C5,6,7,8,12,13,14,15 in the Lite Dac. I read more than once in the thread that the caps are being replaced with ".1uf 63V Polypropylene Film caps". But what does .1uf mean?   Does it mean the...
