I plug mine directly into each amp's dedicated line. Surges etc. are a conern, however there are few "protective" systems made that will not impact your amp's performance. A friend and I have tried various products, which at first we think made a marked improvement, but after listening to the system with protection, then switching back to a direct connection, we've always found the direct is better. Then a few months latter, we'll try another scheme to improve the sound and have repeated our findings. There are places in cities where the electrical lines indeed sound trashy because of to high a load, noisy transformers, etc, and for these areas I'm sure the surge protection schemes may improve the electricity so much that filtered sounds better even with the current limiting factors these devices seem to impose. If you live in the heart of a city with lots of industry and heating cooling needs, you may want the protection of line filters/regenerators. If you live in the suburbs you may have similar findings to mine.
If you listen late at night, you'll almost always have better sound.
Good listening,
