oops I apologize to my pc messed .. I corrected .

@vlachI have a AK100II and using the balanced output in the input CDM compared to the SE you get greater thrust and dynamic sound quality have not noticed any difference between the two outputs of AK only a more vigorous push my CDM pilot in my audeze LCD3 SE smoothly! It is a headset that...

  Just find these Sonotone 6111 with heavenly tip just will install on the pcb see what they sound like ... I love this amp sounds really really good ..

I installed the 5719 sonotones for about a month and compared with philips series there is a clear difference then using the balanced you get a lot more dynamic and full-bodied ... great amplifier

beautiful show ... a dream envy ..

I just saw the notification .. beautiful speechless ... dorado woow! ken a great job alo team really ..

The 6832 valve in addition to spreading heat consumes a lot of battery! 0.8A with two tubes ... but I'd be curious to try it .. when will start to get cold below zero you can use it to warm your hands! joke!

I consider it more a great amp that can drive any headphone iem to full size as much energy, and not underestimating the very silent balanced inputs and outputs good range of excellent construction Battery .. although many Chinese have your amp off for me is always alo an upper object.   cheers

Good work and great news ... hopefully give AK the usb update also for ak100ll series etc ...!

I bought them two months ago and have excellent ear for that price range at the beginning they were a little "cold" as sound but after several hours of listening have become very pleasant easy to fly and very well built aluminum and complete with accessories bag cloth for transport etc. really...

I used lcd2F with different amp and I was never sorry for me I consider it one of the best pleasant headphones with many kinds of music .. never tiring within certain limits that every headset can have ..

I never had problems with both PC and with iphone 6 (DAC) .. great amp so much power and dynamics even with very difficult to drive headphones ..

The differences are certainly in digital signals between a dap and the other can affect many components even the mechanical cd between one type and another keeping the same dac there can be many differences on the final sound ..

Really interesting should be pretty comfortable anyway to try definitely nice job! being open there will be interference from outside noise ..?

Great news of the weekend ... I would be curious to test it in combo with the new Isine10 or 20! 

  Quote: ok waiting for new info ..   thanks!

Does anyone know by chance if the Cv5 will recharge via USB?

Great combination! CV5 say that this is also the most powerful of the CDM .. although I love this CDM machines are spectacular both construction and sound .. I think that each of them has the right combination an object that contains dac + amp is more practical but separated you can achieve...

The major disorders are caused by the GSM signal is very annoying and I also happen with other portable amplifiers near the phone with wi-fi did not give me never bothered on CDM as there is more tubes subjected .. on the old radio and its phono stages they put on a metal shielding valves around...

I used many times iPhone6 with CDM and has always worked well ever interference it can sometimes be useful noises unplug the usb adapter and reconnect it also depends on the room that you still use the app you get a nice sound.

Perhaps for the modification? Ken says that all newly produced CDM that will change ..

Ok thanks Ken for information, looking forward to this new Cv5!   regards.

Interesting talk, but this change even if it is not used on AK70 can improve use with iphone? the rest of the work pc mac etc remain as before? can only improve everything? thank you.

This AK70 is doing successfully .. are very fond to my AK100 .. but I am very tempted to see this ... AK70 comparisons of sound for both for those who try it ..

The combination of each tube with the CDM may give you different nuances in the sound but we say that in general, if a headset sounds good already doing "rolling" pui find the best result also depending on your taste ..
