Do you remember the other options?
 
Are the other options still possibilities or was one configuration settled upon?

 
The best bet would be sending Masuda-san an e-mail and he'll let us know

I'm copying the e-mail I received as follows
 
I will ship the 404 was completed.
 
And I will ask you a question about the connection of balance input and output.
 
Please choice each one.
I make by your instructions.
 
2.5mm 4Pole Phono Jack
1. Input - General , Output - General
2. Input - AK , Output - General
3. Input - General , Output - AK
4. Input - AK , Output - AK
 
Note

Ring1 : R+
Ring2 : L-

<AK>

I'm waiting your reply.


 

 
The choice could depend on what connectors are preferable

mmm......loving  my 404 (dumped my 395). Pretty powerful portable amp. Out of the unbalanced 3.5 mm., I never get past 8 o'clock for headphone use. It gets too loud too fast. Fine-tuning the volume pot is like a game of millimeters.

Why the selling?

Anymore feedbacks on this Amp?
