Not really. I've had countless people swear up and down they had a need for a three gallon brewer but still hadn't maxed out there dual 1.5 brewer. Kudos to Bunn for making a dual 3 gallon that didn't look small bathtub.
The sad fact is with the Titan if you don't have 3 phase 240V in the building a dual 1.5 will be able to out perform it by 10 gallons an hour. So Bunn essentially created a worthless product to a lot of people.
