Enjoy. I just swapped the AD8610s for a pair of OPA637BP. Its a straight swap. These opamps sound pretty good.

Wuwhere, I,m glad you are enjoying the Neco V2, I agree with your impressions of Sound Quality. If you have a way auditioning a Shure SRH840 with the Neco V2 try it is an excellent combination.I have found that with normal use the battery charge last 20 to 22 hrs. I usually recharge it for 2 to 4 hrs every ten days. Which op amps are you using?

Fedex just delivered my new SRH840.  Hope it gets better with burn-in. My UE10Pro is much better.

OMG, stunning SQ fed from D10's preamp out. Still getting used to it (burn-in). Will do a full size review in the next couple of days.

 

[wuwhere]

Let it burn-in for about 100 or so hours first. The opa637bp is better than the ad8610. Its only downside is reduced battery time. But you can leave the charger plugged and that solves the problem.

This thing can drive the 300Ohms HD600 without any problem. My other portable amps can also drive the HD600 without any problem.

Oh, come on, What is your point?
My iaudio 7 can drive HD600 without any problem either, but they sounds totally different. The Neco dual mono portable amplifier could be used as high quality desktop as well as portable headphone amp.

just got one of these ,ive always been very happy with my caffine ultra but this is something else ,no subtle improvement here ,it blows your socks off! the soundstage is bigger and very 3d! ,the highs clean and clear and the lows extend very deep (deeper than the ultra with bass boost on) it just sounds amazing even with loads of burn in to do.
im thinking the two single opamps pair well with the twin dacs of my sflo ,but my hunt is over for my perfect sound ,you think youve found it, buy something else ,then something else then end up with a massive jump ,well pleased

My V.2 amp has done burn-in over 120 hours.
I've swapped Op.amp OPA837,OPA211,OPA627BP,OPA637BP...etc.
Finaly I decide to use LT1028ACN.
The sound is very clear and transparent and sound stage is wide.  Bass is more deeper then else Op. amp.
 
This dual mono CMoy based amp is wounderful.

 

[wuwhere]

I may have to try that opamp (LT1028ACN).

Hi sulcata-geo, I too would love to give one of these LT1028ACN  a go. Please advise where you obtained them as I have tried a few locations and there seems to be a minimum order of 50 so far as I can see. I'm based in the United Kingdom and cannot find anywhere to buy these op amps as I would like to start "rolling". Any help from you or any Head-Fi's would be appreciated.
