Hi,
I bought a Matrix M-stage USB DAC and I would like change OPA2134 with another op-amp...
I read in this forum and the best chip for this amp seem
 
AD8066
LM4562
OPA627
 
How I use them??
 
AD8066 is only SOIC....I need a DIP adapter?
 
LM4562 is plug & play...right? biasing??
 
and OPA627??? 
 
Sorry for my english
 
Thanks

LM4562 is a good upgrade over OPA2134.

Can I insert it directly into M-stage?
 
Nothing resistance? nothing biasing? 

 

[G.Trenchev]

Yes,just mind the orientation.

 

[Derrik86]

Thanks a lot.
 
 
And AD8066??  have you listen it?? 
 
I need only a dip adapter for use it? nothing biasing?

Hi,
 
I think you´ve got a missinterpretation of what biasing means .. biasing into class A is a additional step to reduce thermal variation and crossover distortion. It´s a "can do" not a "must".
 
cheers

Hi Neopac, you think good!
 
I thought Biasing was a Must!! 
 
Thanks!!

Other opamp recommended for M-stage??
 
I have a Q701 and I would like neutral response, good details, Prat sound with good dynamic.
 
Thanks

My favorite now is OPA1612,better details than LM4562.
