Keep going Larry, keep going...
Thanks for all your hard work.

Skylab and HeadphoneAddict, as a newbie I cannot thank you enough for the time, expertise and effort that go into your reviews. You have helped me get started in this interesting and expensive hobby.

Much of my iBasso D10 review is typed up, but I need to go get some sleep and next time I have to start rolling opamps - especially to try the AD8066 main with AD708 buffers, and AD8656 main with bypassed buffers that HiFlight recommends. I am pretty sure I have all these left over from my D1 opamp rolling experiments. I will also try the AD8397, but I'm pretty sure the OPA2111 went away with the D1.

Hi Mr Addict , wanted to ask you something about D10.

between D10 and predator , which one has more synergy and power to drive better headphones?

 

[joincoolkidclub]

I noticed no mention of Beyer Dynamics. In considering the Nuforce Icon Portable, does the amp not provide enough drive for dt770's?

Maybe your native language is not english, so let me point you to my post right above yours ^ where I said my D10 review is not done yet and where I said what things I still need to do before it is done.

I do not have any Beyer headphones at this time. I have owned two pair of Darth Beyer V3 and each time I sold them because my re-cabled Denon D2000 sounded better. I don't know how efficient they are for the various models which have various impedances, but I imagine if the impedance is the 32 or 80 ohm they should be fine with the Nuforce.

Anyone know if it would be ok for me to plug my Logitech PC speakers into my Vivid V1? They are powered separately through an outlet.

That will be fine. Just use the V1 to control the volume. Turn the V1 volume down and turn up the active speakers most of the way (or if they are noisy in the background as high as you can without noise). Then with music playing turn the V1 up from zero to whatever volume sounds right. It can put out a lot of current but I don't know how much voltage it can put out since it is charged by 5v source, but it should work fine. It's a headphone out not a line out, which is why I tend to be cautious.

Thanks! Works great!

I am new and trying to learn as much as I can. Yesterday I ran across an interesting site, theaudiocritic.com. To the extent he is correct, many of the folks on this site are wrong, or there are problems with his methodology and he is wrong. I would like to read some comments about this.

GO Larry GO!!!!

Listening to D10 right now with the AD8066 opamp, and stock AD708 buffers. Very nice, and while slightly different than stock which I love, I could live with this too. Next will be the AD8397 opamp.

This is what I have on hand, and need to see what HiFlight recommends or knows works

What does "dual channel op-amp" and "single channel op-amp" mean?

Which is the difference?

Thanks

Dual channel has two amplifiers (can amplify two signals)
Single channel has one amplifer (can amplify only one singnal)

What do you mean for "two signal"?

Which case do we need a double channel in?
