Headphones need power so that the drivers in them can produce music. More inefficient and/or higher-impedance headphones require more power to properly control and move the driver to its full potential.

 

I tried :#

You did very well, thanks! :bigsmile_face:

 

So, the O2 may not be ideal for, say the 300 Ohm Sennheiser HD 650, but pretty perfect for any low impedance IEM. Well, I just love the sound of the O2. my mini review here.

Has anyone been able to compare the 627x with the Triad Audio L3? I've always regretted selling my L3, but I don't really think I can justify paying the cost to buy a new one so I'm looking for something comparable.

I am also curious between the two portables amps.
The 627/627x is one of the best portable amp for me.
It's pairing very well with Grado headphones.
But not so good with Audeze lcd2 or lcd3, the RX mk3 performs better.

FWIW, the O2 easily powers my 300 Ohm Sen 650s, my 300 Ohm Beyer 880s , my 600 Ohm T1s and the harder to drive, but low impedance 701s.... and does it all on low gain.

I found that it really struggled with orthodynamic headphones. That's what I meant by insufficient power.

When you say struggled, what do you mean?  Couldn't turn it up loud enough, or had to use high gain ??????

post #322 of 379

Can anybody confirm if the original 627, micro (627) and 627x sounds any different. I've read in a review on the internet that the 627x, besides having a louder volume output than the micro, sounds the same. How about comparing the two to the original 627? Anyone?   

post #323 of 379

Is the volume output on the original 627 and 627x identical?

Had to use high-gain and the orthos just still didn't sound like it was receiving enough power.

That's interesting.  Were you able to turn them up loud enough?  Which orthos are you speaking about?

Think they were loud enough...just. They were the HE-500s but I don't know if it's just me or whether they're truly underpowered compared to when the 627 MICRO was used.

Have you been able to compare it to a desk top amp?

The O2/ODAC combo is definitely a beast.  I expected it to be bigger.  I don't have either of my ports anymore to compare to however.  I really wish Caesar would come out with 627 dac/amp combo.  If he would through the odac into the 627 I would definitely buy one.  Even if it means putting it back into the original 627 case.  Anyone else?  It is possible that if the demand exists he would consider it.

Yea, the schiit lyr I think it was. The 627 and lyr sounded much closer than the 627 and O2 or lyr and O2 ever did.

My portaphile 627 finally arrived and I've got to say, it looks and feels a lot better than the micro. Resemble an elegant drinking flash, just so elegant! I sure won't miss my micro. From the contoured and smooth metal body to the beautiful coloured portaphile 627 logo on the front faceplate, just stunning. I just love the look of the big 2.5mm power jack and caution info, gives it more industrial look.
