i read something somewhere about HT omega not having the ability to use dolby digital due to licensing, something to check out before you buy. the asus xonar stx cards are very good for music and movies but do not have hardware EAX. there is a software package you can download but i hear its not as good. sound blaster has eax and dolby but clarity is less than asus or ht omega
I too noticed it while trying to decide which of the Claros would best suit my needs.
From my comparison, it's the Claro Plus with an additional set of capacitors to suppress the loud 'POP!' noise when speakers are plugged in or removed.
I emailed them asking when it will be available and they responded saying it will be on Newegg, Amazon, and their own store sometime in the next week or so at the suggested retail price of $185.
P.S. The eClaro already has the anti-pop circuitry, plus the option of swapping the front/headphone opamp to change the 'color' of the audio for the same price. If you don't particularly give a hoot about sound color the choice comes down to which slots are available on your motherboard and breathing space for your other expansion cards.
