In my experience (I own both, on separate systems) the Tranquility and the Tranquility SE DACs are worth every dollar in this price range (in the OP setup). Dollar for dollar, these are amazing DACs when properly set up and with the appropriate cabling to match and facilitate them. Also, customer service is extraordinary with lots of tips and suggestions in the setup that really pay off in a quality listening experience. Even though I've owned these for some time now, quite often as I listen I am just amazed by the experience and how life-like and non-digital the experience is. Give them a try.
