This morning, I just happened to find the following post in Xin's Cool talk. There's no reason why I don't put it in here
Quote from Xin's:
"No kidding. After another sleepless night, I just finished the design of V3.0 of SuperMacro.
As much as you do, I too hate endless upgrading. So, I want to fix it up this time.
Basically, V3.0 is a true PPA type amp in the same tiny credit card size case (Kudos to the great PPA project team!). I.e., three seperated channels (L, R and G). As far as I know, this is the first and smallest PPA type portable amp. It is not a compromized version of PPA; actually, it is even more customizable.
Now, the ground channel is identical to L and R channels, i.e., it can use any OPAMP and up to 4x buffers (BUF634 etc.):
When the ground channel uses just one high-current opamp, it is basically a V2.0 SuperMacro.
The ground channel can also use one opamp plus 1 or 2 buffers. This configuration can still have the maximum caps (i.e. up to 6800uf like V2.0). This configuration can provides much more power (current) than above, good for K1000 cans.
The ground channel can also have opamp and buffer sockets, so you can swap any opamp and/or add up to 4x buffers. However the caps will be reduced to 2000uF. Good for DIYers, lots of fun playing their beloved opamps and buffers.
New PCB boards should arrive this Friday and I will post a picture this weekend. If you have placed an order and don't want to wait for V3.0, please let us know, we'll then send you a V2.0 ASAP. Note: upgrading to V3.0 will not be free, because of lots of new stuff.
All dear current SM owners, please be patient for upgrading, allow me to perfect everything.
Please do NOT order SuperMacro now, until I figure out some easy-to-choose configurations for you as now things get really complicated. If I offer all the options that V3.0 can offer, you'll need to get a PhD first before you know which options are rigtht for you. If you have any suggestions, please!"
