If you have 6k to spend on two 30.2s, you might want to also consider dacless Isabella/30.2pwr. This would only be two hundred bucks more after discounts (if my maths is right).
Yes - If you own a RWA component and buy and Isabella (or buy an Isabella with a new RWA component), we take 10% off the Isabella.
So 10% off $4000 (Isabella linestage) is $3600, + $2600 (30.2 power amp) = $6200. Two Sig 30.2 integrateds = $6000.
Looks like Kitten's math looks correct.

Now you've gone and done it.....I'm going to have to get two 30.2's! Each with volume...so I can balance L and R...all without a preamp!
That'll work fine as long as you don't mind raising/lower two volume controls at the same time. Using a remote for this is not flawless in operation because if one amp receives a command and the other does not, one will be louder than the other, etc. Of course if you are controlling the volume by hand, it will be fine...
