Technical specs looks the same, except no opamp info.

That's an old pic of the previous generation Minibox.  THe one I had used buttons not switches for the PtoS and bass boost.  Don't know what's going on here.

ES is a tuned version of E+. While E+ is based on AD8610, ES is based on OPA627.

there are tests on abi that show opa627 behaves  almost the same as ad8610 in miniboxe+, so it must be basically the same

 

amp inside. i hope that new name ES means single ended and there will also be miniboxEB - balanced amp.

I have yet to hear anything beat OPA1611, LT1677, ISL28127, and ADA4627-1 in the Minibox-E+.

 

I emailed them to see what else might be different, if at all.

Any idea what the "ES" stands for? I'm guessing it is not "Elite Series" like Westone...

Head-Direct told me it is just a change of opamps.  Some upgrade/update.  The chip is expensive and for the price of one from Digikey, you can get 2x ADA4627-1, which is much better than 627 in both the Minibox and my Compass DAC.

I am confused ny the new pictures on the website. I was very interested in buying the Minibox E+ because it had the bass boost and 'P to S' buttons, but the new ES version looks more simple with just a 'gain' button?...Can anyone confirm it still has both options like E+?...

It most likely doesn't.

Have you asked Head-Direct?

Yes , they said it was the same,just a better sound output, but it really doesn't look the same.

They said it would be easy to see once i received it!-Not sure...

How is it better...I was under the impression that the OPA 627 and AD8620 were pretty much top-notch  confused.gif

Just received a message this morning from Ms. T in customer service: Only change was the op amp "upgrade" from an AD8610 to an OPA627.  I wonder how this will effect the overall synergism of parts to sound?

The new version does not have the Bass boost or PtoS.  That was the deal breaker for me.  I heard rave reviews about how this amp was just made for ER4.  As much as I LOVE my decade old ER4 I have to add a little bass.  The circuit on the E+ is way better than a software EQ from a DAP.

 

Long story short....I found a used E+ for sale on the forums here and my ER4s have never been happier!
