HA-5002 Buffer output current protection

[bpribadi 0]

Hi experts! need your advice...

 

On Tangent's page about buffer:

http://tangentsoft.net/audio/ppa/amp/tweaks.html#par-buffers

 

It said there that HA-5002 sounds so good because it has no output current protection. Internally true, but I saw in the datasheet, that externally, we can use resistor to limit the output current, thus protect the buffer from short circuit.

 

 

My questions:

 

1. Does PPA use this RLim to protect the buffers? Well I didn't see it on the PPA schematic.

 

2. Will there be any effect to the sound quality by using RLim to protect the buffer?

 

HA-5002 datasheet:

read page 4

 

Thanks!

Looks like I will use this approach to protect the buffers, for my headamp that I'm going to build soon:
