KOJO KM01-BRASS : With a (32Ω) 20mW +20 mW impression and appreciation thread - Page 3

post #31 of 243

Hi Rudi, I really share the fun you have when seeing pictures of your setup.. it has been really enjoyable to see you tirelessly mix and match different gears to find the sound you like... I think you should really mod your AK to obtain LO as it seems that you enjoy pairing the AK with different amps... how do you like the DB2 btw? it has two 8740 chips same as AK120.... I feel the sound of DB2 is really smooth and laid back.

I like my DB2 , my done the modification my DB2
My DB2 mod as external DAC is the easy way to upgrade my AK 100 / AK 120 to the next level
I have more balance from AK 100 / AK 120 with my DB2 mod
After mod my DB2 is not laid-back.

Congrats you like the SQ from Ko Jo KM - 01 amp like me

3 DD vs SM 64 V1

3 DD
High : more extended , more clear and clean and smooth
Mid : more clear and clean , SM 64 v1 a bit forward
Bass : very Clean , very detail and faster bass speed than sm 64 v1
Soundstage : wider and better depth than SM 64 v1
Separation : better separation as well

If you like airy , very detail , clarity , fast speed and very good bass impact
Than 3 DD is your choice

I like the airy and very clean SQ

I have tried some alkaline battery AAA for my Ko Jo KM - 01 amp

The best synergy in term of SQ is : Duracell alkaline battery
High : more detail , very clean and clear and very good clarity
Mid : more clear and clean too
Bass : better bass impact and improve detail , faster bass speed and very clean bass
Soundstage : wider and more depth too
Separation : because of improvement the clarity , the separation become better too
That I can hear the instrument placement more accurate
My IMO

Energizer is good in high , but less bass impact

Panasonic : is a bit warm

Sanyo : is warm too

We tried many mini to mini from many brands

The winner in term of SQ is :

Tralucent Audio UBER cable mini to mini

Runner up is :

Venture Craft Audiophile Grade Edition

And

My friend diy mini to mini with oyaide gold connector


Note : to improve the Sound Quality mini to mini cable is very important
Beside battery as the heart from the amp


IMO

I want share how to handle with care your Brass body from Ko Jo KM - 01 amp :












Rule 1 : brass is very fast oxidise

To pretend fast oxidise process , please do as follow

1. Every time you change the battery , please clean up your finger print with lens cloth or
Eye wear cloth .
Finger print is oily can fasten oxidise process.
2. Wrape the whole body with lens / eye wear cloth like my picture above
3. Wrape with anti slip mate and use rubber to tighten the wrapping units

Enjoy your longer shining your brass body like Ko Jo Amp

Rudi, thanks so much for sharing your method of preservng the shine on your KoJo amp. I am sure there some folks here will benefit from it. One of the reasons why I am not too keen on this amp is its upkeep and weight :etysmile: I am just plain lazy :D

I also bought this KOJO and really very very clean and smooth sounding. Of course only for driving low impedance headphone or IEM. Running direct out from my HM801 with "Crystal cable for mini-to-mini interconnect powered by Crystal Piccolino" http://jaben.net/shopping2/Crystal-cable-for-mini-powered-by-Crystal-Piccolino.html, . Yet to test on my Grado RS1i.

 

There is one question for my HM 901, as 1 could not connect direct out due to connector from HM 901 not the mini type. Anyone know any adapter to mini?

 

Reason for buying this as i found only one AAA battery and i prefer this type of battery rather than built in type as i don't like to send back for replacement in near future (for built in battery) when battery get weaken.

 

Have been using this "Crystal Piccolino Cable" which i got 2 pieces. Could someone kindly advice any alternative to this type of cable and of better sound than this, any?

 

Rgds
