Actually our 502DAC PRO used the LME49600, but we discontinued it due to heat and cost. We are designing a new one based on SRC4192 ASRC, dual PCM1794a and TPA6120A2 HP amp. No digital, analog only.
Hi Michael!
In fact, the DAC502 PRO is an excellent DAC! It is heated because of a small inaccuracy. This is easy to fix. And the stud will be slightly warm. In this case, the quality of the Sound remains unchanged.
Michael do the following
At LМE49600 soldering iron unhook the leg number 1 from the common ground, just pick it up.
Next, connect the leg number 1 to the ground through a 180 ohm resistor
It is necessary to apply, as best as possible a resistor for Sound
then the temperature of LME49600 decreases sharply.
Guys if you need a playing DAC best of all for Sound I advise not to waste time and money and look at the 502 model.
Best regards,
Bason
