By the way,

I just tried AD797 today and the bass is much stronger and tighter than OPA627. Please try this opamps.

 

Where can I get this op amp in Singapore ?

 

I read from Xin's forum that its give a warm & lifelike sound.

So Sorry I don't really know where I could get them in Singapore. I bought it from www.digikey.com and delivered to my door.

I think I wanted to cancelled my order already ( 3 months & still no new yet ). The waiting time is superly long.

 

By the way, do you need to solder a capacitor on the AD797 as wat I see from Ron's picture ?

It seems like Farnell has the said opamp in stock at about $14 per piece. You might want to try them.

Which one should I buy ?

AD797AN

AD797AR

AD797ANZ

AD797ARZ

 

Is it the bigger the brandwidth, the better ?

 

Thanks.

They are all the same. The non 'Z' version is not ROHC compliant. This means that it contains lead in it. This makes no difference to you unless you want to export the device to the UK. Even so, get the 'Z' version as it's ROHC compliant and cheaper.

 

The 'AR' version is the surface mount version. While the 'AN' is the dual inline package type which can be used in a socket.

 

If I remember right, the amp can take the socket type so get the socket type.

 

Just check if it can take single or dual opamp per package.

Let me get my SMIV first.

 

Basically, this is my first portable amp & I might have a problem identifying the channel. Single & dual op-amp ? How is the configuration like & what it mean ?

 

I had also ordered a pair of compensation sockets for AD797.

An AD797 configuration picture will be much better.

 

Thanks.

I will be getting my Super Macro 4 soon.

 

Any interconnect recommendation ?

I was looking at the Cotton Mini to Mini from www.aloaudio.com.

 

Thanks.
