Two perspectives here, money vs value. Sometimes money ceases to lose much of it's value when meaningful change comes. I consider the 006, Gaia and Tubulus Ximius I2S cable as a downright steal at their full retail prices.
Obviously I can't tell you if slightly less money spent on a ddc or quality I2S cable provides greater value since I'm not using money as part of the value equation here. I could choose to speculate endlessly when it comes to value equations based on money spent, all I know is what I hear and what I hear far exceeds my expectations going into these purchases. Beyond that, these three components will be my reference digital source for some time to come, not bothered there may yet still be better digital sources. Fully expect I'll have an itch to change at some time in the future.
And if we want to go into value for money evaluations, I'd likely tell you the Laiv Harmony dac is the better value, slightly less resolution may not be exposed in all systems and some may prefer the presentation.
