Do I need 2 627 amps? Are they mono? Is this the reason why I would need the dual adapter to mount the chips?

Yes. They are mono so you will need 2 on a suitable adapter (as provided with the DIY)

Hi, fellow E12DIY-ers!

 

I have actually been using the E12DIY for a year, mainly just swapping opamps and buffers. However, I have not tried tweaking the bandwidth of the amp and so was wondering whether I could get some tips from those of you who have done it. The user manual only has a very brief and simplified guide to changing the bandwidth and to me, isn't detailed enough for me to be confident about doing it.

 

Would I need any additional tools other than the two resistors provided in the tin to perform the bandwidth change? What about the two little rectangular pieces also in the tin? What are they for?

 

And also, what are the benefits of changing the bandwidth?

 

Thanks in advance! :)

Tell me please, OPA827 I need two pieces? Or one piece as a Muse?

Thank you.
Here's another question.
I wanted to buy buffer HA-5002, but there are different HA2, HA3, HA4, HA7
Which suited me, and if there is a big difference between them?

The 5002 buffer needs a pin out conversion to work, none of the versions work standalone, easiest way is to purchase a set that has already been converted from headfi member hiflight: http://www.head-fi.org/u/22191/hiflight

They are referring to the different packaging. Basically you want HA9, or SOIC8 packaging, as it is the only one that will fit inside E12DIY.

 

Then you'll need two of the special HA-5002 BrownDog adapter. How to mount them correctly has been mentioned in the past in this thread, so go and read them.

 

...or buy a pair from HiFlight.
