Well said Bonjovi.

It’s not your "father’s preamp” anymore. The software and hardwareOn these components are so interconnected that any changes, no matter how minor, require a complete re-check of the entire operating system.

Because of the complexity of the on-board technologies we are not aware of any company offering preamps that has not encountered numerous delays and glitches. To make matters even more difficult, there are often major compatibility problems between otherwise well-designed source components. You just never know what you will get in that HDMI handshake (Sometimes it’s a “joy buzzer” instead.)

In any event, we and Sherwood Newcastle continue to move ahead through the minefield of software/firmware challenges. For the record, the 990 was a relative piece of cake to refine compared to the 997.We are getting there, but we are being extra cautious.
