Well, I just bought me one of these... cool.gif So now I'm even more interested in this thread and opamp rolling, especially when my Cube arrives! rolleyes.gif

Depends on the opamp and if its a single or dual chip. Single chips need the adaptor and a pair of the chip (one per channel). Some adaptors require soldering while others are plug and play. Which one you get depends on the version of the opamp you buy. Duals do not need anything and are a straight swap.

 

For example, the popular OPA627 and AD979 are singles so you'll need a set of them.

Ok, I know nothing about electronics and opamps, but the fact that opamp rolling gives the possibility to change the sound it produces, I very interesting. I might give this opamp rolling business a try, if it isn't too complicated to perform... rolleyes.gif

 

For those of you who rolled opamps on your Cube, can you tell which ones are your favourites and why (what do they change in the sound)? Oh, and if they're a straight swap or if they need adapter...

 

 

Thanks! wink.gif

My Matrix Cube finally arrived, and I'm enjoying it! cool.gif

 

Can anyone who has a Cube with socketed opamps tell if mine, with serial number 201105008, is supposed to have those as well (based on yours SN)? I don't want to open it up just yet, as mine has a warranty seal on one side, but I'm a bit curious and it would be nice to know... rolleyes.gif

 

 

Thanks.

If you plan on opamp rolling you'll be breaking the seal anyway. wink.gif Haven't taken a peek inside yet myself.

Yes, I know that, but if somehow I could know if my Cube allows opamp rolling without breaking the seal, based on it's serial number, it'd be great, don't you think? wink.gif 

 

At least, this would prevent me from voiding it's warranty for no reason, if mine doesn't allow opamp rolling... rolleyes.gif

I bought mine over a year ago and it allows for opamp rolling so I'm sure yours does as well.

 

I really wouldn't worry about them voiding your warranty because of a broken seal, especially from matrix/tam audio.

Thanks for your answer, clams! BTW, what's your opinion about the following:
