In Stock, Good Amp, I'm a Happy Guy!

The following review is for R2-750X5, which is a part of the bundle you are viewing.

Due to the semiconductor shortage, I had trouble finding this unit other places. I was pleased that Sonic had this in stock and shipped it quickly. It arrived in good shape and works well.

The only downside is that RF's documentation is a bit weak. They seem to assume you are already well versed in audio amps and know how to set the various dials/buttons. It isn't rocket science but a few more words might have been useful.
