I'm thinking of building a pimeta-esque amp. I'm going to have LMH6321 buffered OPA627s for the left and right channels. However, for the ground driver, I'm thinking of using the TI's suggest pseudo-ground instead of a 3rd channel. This is an attempt to build the amp using a "star" topology rather than the 3 channel design. Would this work?
The "start" topology. Credit to jcx:
If I did this method, would I have to use the same opamp (OPA627) and buffer (LMH6321)?
And a non-related question: Would there be any benefit in bypassing the opamps and buffers with ceramic and film capacitors in parallel?
Thanks in advance.
