Default Katana Sound Quality Stack

If you have the Sound Quality Op Amp board in your Katana stack have a look at the two green ovals in the attached picture. I noticed that the two standoffs between the Katana board and the Op Amp board on this side were not tight. Any attempt to tighten the standoff would cause the boards to bend. The eight pin connector between these two boards was tight, but the standoffs were not. I believe this is caused by the small board that Allo added to the Sound Quality Op Amp board. This tiny board appears to go under the 8 pin connector.

Changing these two standoffs from 11mm to 12mm solved the problem. However, I found that I needed to leave the two 11mm standoffs on the opposite side of the board as the 12 pin connector on the back of the board didn't seat correctly with 12mm standoffs.

I was not happy with the fit of the acrylic case on my stack and I will not be using it. The middle red oval shows the device heat sink touching the bottom of the top cover while there is almost an 1/8" (~3mm) gap to the top of the posts on each side. The cutout in the top cover of my case does not allow the heatsink to pass through.

The music is great however. I am waiting for my linear power supply parts to arrive and looking forward to the change that it will make.
