Well, did yo check the measurements, both in idle and loaded state? Yes, the DFC consumes MORE power than DFR, it‘s a very simple measurement, and absolutely obective.
You don‘t see that difference? Let me explain why. DFR consumes 40mA at idle, while DFC is draining 60mA. Both values are indeed low. Nevertheless DFC is consuming 50% more. So, why don‘t you see a difference? Probably because you are using it with an average smartphone, that is equipped with a 2500-4000mAh battery. So even if you keep the dongle attached to the phone, it will drain it in 50 to 100 hours. Before that ever happens, your phone will be long recharged anyway, it‘s practically not possible to easily see that difference.
In my use case, on the other hand, I‘m using a simple ipod touch, in order to keep it as mobile as possible. That one has a battery of less than 1000mAh. If I keep even a DFR with its 40mA attached permanently, the battery is empty in a less than a day. An advertised lower power consumption of some components on DFC, leading me to believe the whole device is consuming less power, is an important differentiator. Turns out to be only marketing though....
Btw, you are putting words into my mouth that I never said. Where exactly did I say DFC sounds worse than DFR?
Why would I keep it permanently attached? I plug it in only when I want to listen to music. But I will sit and listen for hours. That’s how I know it uses less battery than my Red did. The first day I bought the Cobalt, all I did was A&B it against my Red for hours. Not to mention that I had the Red for years and have now had the Cobalt for nearly a month. I don’t need measurements to tell me which drains my iPhone faster. In real world usage, it’s the Red.
And it’s icing on the cake that the Cobalt also sounds smoother, more detailed, and with a noticeably larger soundstage than the Red, which is why I sold my Red and have no regrets.
You didn’t say the Cobalt sounds worse than the Red, but you tried to completely discount my opinion that it sounds better, which implies you disagree. All you had to do was state your opinion, not try to discredit mine. This is Head-Fi and people come here to seek people’s opinions on sound. That’s the whole point of these forums. Discounting an opinion as subjective from someone who was an early adopter of new technology is simply rude. How the hell else can one describe sound without it being subjective?
