If you look at the photos, all indications are that both units are exactly the same.
I'm not sure how well either unit really works, as it doesn't offer much in the way of surround decoding. It literally ONLY works with PCM surround audio, which means that's what you have to set your source to. I'm sure many people have used it who have no idea how to set their equipment up right. Don't be one of them.
I expect either will be identical, but totally up to you what to get, and if you get good usage out of your old gear, then more power to you.
But, seriously... Start saving for something badass.
