Post 20530 I explained why. Frankly you have been nothing but cold or off, to me since I disagreed with you only once. It was over the Mojo missing the first second of music. You were defending the Mojo method and I said there is another option. The Meridan Explorer which pauses music playback (for about a second) until it synchronises hardware: other DACs do that too. You come back at me over something else I posted again. Saying AND this AND that, AND the other, yet in my 20530 there a whacking great heatsink applied. Plus full explanation of why I am saying what I said. Yet only two nights before I had to stop chatting back and forth because I was sick of having to re-post. To say what I had already said, then said so the next day. However for your benefit RELIC, here it is AGAIN! From post 20530: Therefor the heatsink could very well be needed for desktop work, especially in hot climates. (I was discussing heat and hoping there was a cooler battery solution. What happens when the battery gets worn was my other concern. Given we just had a mini heatwave in the UK of 35'C. Mojo would struggle to stay on as a desktop DAC if it was charging and playing all the time.) ------------------- To be honest the general attitude to anyone who questions the Mojo in this thread is appalling. Yet it is always said, "Do not be afraid to ask". .......Why should we be afraid then. ..........Not pointing the finger at anyone but stop being princesses to anyone who asks. Maybe it's justified with some trollers if that's what they are doing. However me, I love the Mojo too. There is nothing wrong with modding, trying, asking, thinking out loud, if you have the spec and try safely. I would be extremely careful, and if I had any doubt I simply would not do. Personally my Mojo is as perfect as it can be. I got lucky. It seems happy to charge and play at 25'C and under, but I have not tried it in hotter weather. It doesn't whine. ...However I do worry about the future. If the battery wears and will it mean it is stuck in permanent charge while playing, in desktop mode. (Said in 20530.) However I still have my eggs in the Chord basket the battery is bullet-proof. While I concede the Mojo is not designed as a desktop DAC many of use it as such. My Mojo has never left my home where other folks show us beautiful photos of luscious stacks for portable use. However I have been wanting to address my questions to Chord for a good while. Yet never did because I knew this overall general attitude would be the result. I have had other ideas, but really do you think I should ask here now; anyone?...What a waste; non-shared ideas. ---------------- @Torq Which uses more power to drive? Low or high impedance headphones. I think current flows more freely in in low impedance. Yes I am concerned about another battery's current capacity. However it's also P=VI and it's power that matters too. Higher impedance headphone will drain the battery faster right at the same volume. (It's speed of discharge that causes heat.) See I have thought through my ideas and don't need to explain them. I just need the specs. Right!
