ARC Audio PS-8 Do I really need one

If you are happy with the sound why spend the money?

Its a very nice unit, and I am sure it has its place indeed. I personally have never used one nor do I know very much about them.

What ever makes you happy and sounds good to you is good enough. Don't be influenced by opinions that have an interest in your pocket book but not your best interest.

If you really need one and could really benefit from one and you can afford it.........why not??
