I like to build Cmoy using the PCB method. Which design and opamp sound best with grado?

[tropicalrips 0]

i think if u are making the PCB, should do it for A47 design, it can still work as a Cmoy without the second op-amp.

 

my current fav op-amp for Grado is the ad8620, sounds faster & full body/aggressive, but its in my clone type amp (naca v3)

 

a few people here had brief auditions of this combination, they might be able to giv a more non bias description of the way the amp sounds with the SR80

Jason , if u are building a pcb , can a newbeez like me share it ?,

(I can give a helping hand & share cost. ..., i'm lack of experience , dun dare to start the project )

Tropical, I create the PCB and you sell the part plus component. Together we create a kit that is cheap for people to do DIY. What do you think?

[tropicalrips 0]

i'm in

but with the PCB anyone would be able to get the rest of the parts from SLT

 

we should disscuss further what options/features should go into the PCB.

for a start, things like :

 

rail-spilter

extra capacitors

direct mounting on PCB for volume pot

 

what do u think jason maxed out Cmoy/A47

If we buy the parts in bulk it will definately be much cheaper. Especially people nowadys prefer it in a packet.

 

We can earn as much as 50% if we buy in bulk. If we don't sell much we are in deep sh*t.

Let's start a new thread for discussion.

maybe I can do some thing for this point.

You got the PCB layout?

[digi01 0]

if there is a lot of diy guys to care for it.I think I can make a projects.

 

rudiment ideas about the PCB boards size is 30x22mm.even can make a SMD component version.

yes, we should start a new tread for this.

i had some ideas for board layout, but it could not be done with a breadboard, should be able to get it on a DIY PCB

We got the same mind...
