Thanks Rudi for your valuable feedback. I will order this kind of I/C to try.

 

So far, I am really liking the sound of Kojo when pairing with a modded X3. However, i do not hear big improvement when pairing with DB2 (Stock) single ended output and DX50 (1.5V rms line out). I think I need to try the balance out of DB2 to achieve better dynamic...

 

BTW, I read that there will be DB3/PB3 released next year... so I may not further invest in modding the DB2...

iPhone 4S vs Blackberry Z10 vs SS Note 3 as pure DAP

Power wise for iem :

iPhone 4 s > Blackberry Z10 > SS Note 3

SQ wise :

IPhone 4 s > Blackberry Z10 > SS Note 3

These 3 smart phone has their own strong point

The best bass impact : Blackberry Z10 the fastest overall SQ
The best balance SQ : iPhone 4 S more balance SQ
The sweetest mid : Samsung Note 3 tube like midrange ,smooth SQ

Nobody is perfect in audio world , has their own strong and weak point

Until now Iphone 4 s is still my best smart phone SQ

My IMO

I've finally snagged a bright shiny new Kojo KM01-Brass amp.  Booya!  Not a trivial thing for someone living in the USA.

 

Due to Japanese translation difficulties while ordering, plus no doubt operator error, I've somehow ended up with a couple of extra 3mm mini-mini (TRS) cables also from Kojo (KM01-OP1).  Given the level of Japanese audio equipment quality demanded, I assume that these interconnect cables are of highest quality, which is why I also bought the accessory cable(s) while I had the opportunity.  And I am now willing to sell these spare Kojo cables at basically my cost + shipping; first come, first served.  A unique opportunity for USA and other audiphiles who normally don't have access to Japanese audio equipment restricted to domestic sales only, for a high-end portable interconnect cable at a fairly reasonable price.  PM me if interested. 

 

Here is the translated cable product description from the Japanese distributer:

 

KM01-OP1 EMC shielded cable adopts copper alloy gold-plated PC-OCC transmission of high-quality, plug-in conductor. As electromagnetic guard sleeve, hull is suppressing the influence of external noise.

Both ends stereo mini-plug
Cable length: 110mm

... so again how is the bass on these? Soft and Tubey or Tight like a Solid State. I'm looking for a warm amp for my W1000x, the mids of this amp sound awesome, but I hear the bass is a little thick... might b a deal breaker for me honestly... still I'm sure it's better than my PB1 lol q.q
