Just wondering why you are double amping? 
And does it make any improvements??? :/

Well, technically, he is triple amping in this rig:

i personally do not think double amping is good so triple amping/// :/

Here is a lil rig to challenge rudi i think.

iPhone 4 > Bluetooth > MyST PORTADAC 1866 > HiFiMAN RE-400

Using the iPhone as it is a nice platform that also doubles up as my phone and of course has bluetooth. Then the portaDAC as it has a very high standard DAC and amp, much better than the iPhone has and does this via bluetooth so great flexibility. So why only the RE-400. Well i am really enjoying them but i am mainly using them as they are what i am currently reviewing so they make the rig and all in all, a very good one


 

Thank you for sharing

It is very genius solution from porta Dac that support Bluetooth for you iPhone

How is the sound quality different between the Bluetooth connection vs Lod to mini to your iPhone ?

That white cable actually looks stunning, nice photos too. 

Thank you for your compliment

No wires between DAP and amp... Wow! How does it compete with other portable amps you've tried?


Looking fancy, rudi! How do they sound?

Sony XBA 4 vs XBA 40

Source : iPhone 4 s
Dac amp : Ventura craft go dap x with LME 49860 op amp upgrade version
Iem : Sony XBA 40

High :
XBA 4 : to peaky and harsh
XBA 40 : more refine high smooth and detail high

Mid :
XBA 4 ;laid back and sound not as sweet as XBA 40
XBA 40 : forward and sweet clear mid than XBA 4

Bass :
XBA 4 : about the same like XBA 4
XBA 40 : has better bass detail

Separation :
XBA 40 has better separation than XBA 4, that you can imagine the instrument position
Better than XBA 4

Soundstage :
XBA 40 has wider soundstage than XBA 4

Conclusion : XBA 40 is very good for long listening , not like XBA 4 make my ear very fast fatigue
Because the high is harsh and peaky

This is my personal opinion

Indeed

But why triple amp when you can quad amp?

Why don't you use a LOD cable since your source is the iPod...
