RE: Newclassd (Dexa) Discrete Opamps & my EE Minimax DAC Plus

Posted by Ric Schultz on January 28, 2012 at 13:06:26:
I am sure you are correct. The Dexas would beat any normal op amp. However, the circuit it way too long. If you knew what you are doing you could use just one Dexa single per channel with a coupling cap soldered directly to the ouput jack. This would sound worlds better. I use a single output device with no coupling cap for even more pure sound. Also, all the parts used in the output stage (even if very simple) still need to be upgraded to give the best sound that fits the player. Also the regulators are ordinary in the minimax. I use cascoded current sourced discrete shunt regs on my circuit. Better regs equal better sound. The potential of the EE DAC is tremendous......of course, you would want better regs on the DAC and clock and a better clock, etc.
