Hello everyone,

I connected this weekend my ZapPulse 2.3SE amplifier again and am relaxed for sit down.
Can say that the Dx Blame MKIII-Hx is not my amplifier, this amplifier let me behind too much information.
The Dx Blame MKIII-Hx is a clean/sterile sounding amplifier without space between the instruments.
Am also very surprised to hear that there is no difference to hear between 10uF capacitor or no capacitor in the signal path.

I look regularly this tread for further measurements or changes made to this amplifier.
If there are no changes, I sell this Dx Blame MKIII-Hx amplifier with the heat sinks but without the 2 Torroids.

It was a very educational experience for me and wants to thank everyone who have helped me.

Regards,
Rudy

It appears he said it was a cold sounding sterile amp , that lacked resolution , smearing of details was evident , vs the ZapPulse ..

The difference directly between the ZapPulse 2.3 and the Dx Blame MKIII-Hx are the graphic power and air around the instruments in favor at the ZapPulse.
You get an immense, and especially deep space in which instruments are dropped in a balanced size, you can walk around the instruments as it were.
What is also striking is that by classical or acoustic music, the ZapPulse 2.3 a very balanced sound you hear especially with a guitar much more the wooden soundboard.
When you hear a violin and the vibration of the strings, is much more incitement.

Conclusion is with MY audio set:
Image power and air around the instruments is in favor at the ZapPulse 2.3 SE.
Please note I use for the power supply of the ZapPulse 2.3 SE a huge 2000Va per channel.
Also, I've heard a ZapPulse 2.3 SE with a 1000Va power supply but the 2000Va was the winner.

The technique in class D amplifiers is also not silent, maybe the new NCore ® Amplifier Modules a good opponent?
Who knows

Regards,
Rudy

Canonnica,

Were you able to simulate the circuit as described..? if the simulation does not show the instability, then it may not be the circuit, it maybe your Transistors...
