Hi,

 

I am about to order one of the Audio-gd discrete op-amps (Earth, Moon and Sun) to replace the stock opamp (OPA2134) in my audio-gd FUN. I have read the review of them but still not quite sure which one to pick, so I will go with whichever has the most vote here.

 

Here is a little information about my setup and music preference. After all, I just want to enjoy the music with my setup.

 

Setup:

Headphone: HF2s and K701s

Computer speakers: AV40s

Dac/amp: FUN

 

Music:

A lot of rock and metal

some jazz and pop as well.

 

Please vote whichever you think would be the best fit for me. Thanks! If you'd like to share the reason behind your vote, it'd be even betterdt880smile.png.

 

 

Happy listening

 

Lee

They are okay, you may like Moon or Earth better.  Sun is funky, and quite fun with a Grado.

 

Would you be willing to consider other opamps?  You will love ADA4627-1B's accuracy, refinement, and detail with K701, while its energy will be an addicting match with HF-2.  It will be an upgrade over Earth as well.

Thanks Mad Max. And definitely, I will check out the ADA4627-1B.

ADA4627-1 will require that you solder the chips to a dip8 adapter.  If you can't solder, me or someone else around this forum can do it for you.

Order them as samples from ADI if possible.

That's what I was worrying. I am not good at soldering or DIY at all. I will let you know if I do order it. Thanks. I appreciate it.

A hearty x2.  The ADA4627-1B is currently kicking the snot out of the OPA627s in the buffer section of my DAC.  I voted for the Sun as I enjoyed it the most with the Compass when I had one.  However, after experimenting with several opamps in the Compass, I found that the Audio gd discrete opamps were nothing special.

Well, for a more "musical" sound, I think discrete modules are good choices.  Not the right kind of colored for my tastes with the exception of Sun.

Yeah, I voted for Sun as well. 

 

The best-sounding opamps I've messed with are mostly newer soic chips, and not everyone can solder so many stick to dip8 opamps.  Even I would take an HDAM over OPA2134, lol.

Thanks for your inputs guys.

 

wow..I thought that the earth opa would be more popular. By the way, how hard is to install them into the FUN? Will audio-gd install them to the FUN before shipping it out?

It's really easy to install one of the OPA's. They slot in and out without the need to solder etc.  Open the box, remove one screw, remove the stock opamp and slot in the new, replace the screw, close the box. Done :)

Will SUN sound good with K701s though?

Will depend on you entirely.  You may find the combination fatiguing.  Or maybe not, it is worth a try when you get bored, lol.  Also, Sun sounds good with or without the ground wire connected to its spot on the board.  You might like it better one way or the other.

personally I prefer other discretes more than the aud-gd ones, the dexa range is cleaner sounding in all aspects (no affiliation) but these days I would build my own. the gen2 burson is very good too IMO, where the gen1 is basically the same

Earth is the most balanced of the 3, Moon sounds really "tubey"(read "distorted") and Fun has a very strange sound that seems to be missing a lot of stuff: http://www.head-fi.org/forums/f6/audio-gd-discrete-op-amps-reviewed-OPA-earth-OPA-moon-OPA-sun-v-2-a-397691/

Indeed, Burson V2 is basically Earth V2...it does the same thing, just clearer and more accurately.
