Portable Headphone Amplifier "WAGNUS Bialbero Epsilon S" impression and appreciation thread - Page 9

Great news Mr Masanori the designer of mass kobo 385 is also working on an adapter for BA IEM, so there goes the hissing problem. Looks like saving for hm901 is going to be put to use for mass kobo 385.

KoBo 385 Is 4 AAA battery operated amp
I have not try with 75 ohm adaptor from my Er 4 P , can be reduce but reduce the SQ too.

My IMO
The hissing is sharper than Ortofon MHd Q 7
Specially for BA iems , with my UM 3 DD less hiss
If you pair with headphone has no hiss

I can also hear the hissing when I used my TG!334 with the Mass Kobo

Hiss is apparent with BA iems.  Even my FAD Heaven 6 hiss when using Mass-Kobo.   Dynamic iems has no hiss or very minimal hiss.    TG334 hiss quite obvious.

Today I went at Jaben Jakarta and tried for the second time Mass Ko Bo 385
The hiss is still there even with
Dynamic Driver from Shure 215 limited edition blue colour
And FAD Heaven 6 has the same hiss .
Only with my UM 3 DD has very minimal hiss.

Yesterday we have compare many portable amps vs Wagnus and Ko Jo Amps

The winner is : for Sound Quality not power

Ranked number 1 : Wagnus Epsilon S
Ranked number 2 : Ko Jo KM - 01

These two Amps are very excellent pair with all iems and Ciem and low impedance
Headphone
Is only good pair with high impedance headphone and Orthos ,because of the power and current

My IMO

From these audition we have the result :

If we want excellent Sound Quality , we can not have Big Power at the same times

If we want big power , we have only good to very good sound quality ,

we have not find portable Amps have excellent Sound Quality with Big Power
And normally no hissing


Please share your opinion here

Thank you

Hi Gavin
After long time listening Mass Ko Bo 385 and because of the hiss , I just decided Today follow you to buy one

Mass Ko Bo 385 amp .

As I told you before , I like the SQ from Ko Bo 385 , i hate :Donly the hiss biggrin.gif

My ranking from these 3 japan high end Amps as follow :

1 . Wagnus Epsilon S
2 . Ko Jo KM - 01
3 . Mass Ko Bo 385

Wagnus Epsilon S is combination the clarity from Mass Ko Bo 385 and very sweet mid from Ko Jo KM - 01
It is excellent for all rounder music from jazz to classic

Ko Jo is very sweet and intimate SQ like tube
It is very good for jazz vocal , country music

Mass Ko Bo very good in detail and clarity
It is very good for instrumental music with percussion , classical music

Minus from Mass Ko Bo is : HISS
The rest you will love Mass Ko Bo 385

Note : these 3 amps are not so good for high impedance headphone like HD 800
And Ortho like LCD 3
These 3 Amps are very good to excellent SQ to all iems and low impedance headphone
Except Ko Bo 385 because of the HISS

out the box my new Mass Ko Bo 385











Source : AK 120
Amp : Mass Ko Bo 385
Iem : Tralucent Audio 1+2 with UBER cable balance RSA
Cable : Tralucent UBER mini to mini
Norse Audio Adapter RSA female to mini
SQ is very good , if no HISS IS EXCELLENT



My IMO
