Germanium's Sound blaster ZXR mod thread - Page 6

post #76 of 139

Yea I wouldn't have believed the end results came from this mod (+ upgraded opamps for my exact sound) if I hadn't done it myself.  I was expecting less out of the DC cap mod and more from the opamps and that ended up being in reverse.

Hi Germanium and all I've been following this thread for a month

What captured my interest is that I'm currently building a ES9018 DAC with 992Enh opamps from Sonic Imagery Labs to replace my ZxR
Before I finish the DAC project I have swapped the opamps and already made a huge improvements

I will make this mod to see if can further the quality of it

Got a plan to make the whole thing neat and tidy

Will share once I got it done

 

Happy modding!

If you have any questions just ask.  Like I mentioned before, you don't want to use any type of copper (even solid copper) wire to make it neater.  Mine isn't laid out perfectly, but it works perfectly   :beyersmile:

I found another good supplier for high quality capacitors and these boys carry lots of brands from Sprague to NOS.

Some of those are insanely expensive, so just keep looking until you find one around the price or below my ERSE PulseX ($4.50), but some are over $55 a cap..

I wanted to mention this in case someone hits the wrong brand.  The capacitors range from $3 each all the way up to above $500 so don't think they are all that high, but I would go with ERSE due to the price and the fast/cheap shipping.  You can get my ERSE PulseX capacitors for like $4-$5 each.

I updated my photo on the original post to include all the necessary mods. Will post a new picture of the completed mod later as to be honest I'm enjoying it too much to pull it out to take pictures of it but will next weekend.

I've always thought those Op-Amps are so huge and with how my GPUs are arranged I couldn't even use them.

 

Good job on the mod.

Neat job especially with the bread boarding the caps though like NCSUZoso mentioned it would never fit in my situation. Is there any significant difference I.E. improvement in sound compared to using the discrete opamps themselves? 

post #86 of 139

Those are actually considered the most discrete because everything stays analog the entire time

 

It works on the same principle as this:

 

 

 

I was looking at these which are about the same size:

The opamps alone already improved a lot and the cap mod really brings it to another level

Transparent mids, cut through but not over done highs is guaranteed

 

I could say if the opamps mod scored 65/100, it well worth a 75 plus the cap mod

post #88 of 139

My suggestion is...

 

don't buy the audio-gd discrete opamp

post #89 of 139

oh I'm past the opamp stage or I wouldn't have done this mod (check my sig for details):

 

 

 

Now lets go to a different subject, Creative's Stereo Direct says it does this:

 

Quote:
Stereo Direct  is an option for direct playback to stereo speaker channel sampled at 192kHz.

 

You lose SBX Pro, DTS Connect, DDL and for some reason the Equalizer??  You have to stop any audio source from playing and close it or you will freeze the PC.  What I want to know is what exactly is this doing?  You can't change the volume through windows, it has to be done on your output (receiver/powered speakers/etc.).

Indeed Germanium I got a question after the mod.

 

What is the purpose / advantage of having 12uf / 24uf for the bypass cap over the usual 0.1uf film cap?
