O2 AMP + ODAC - Page 11

post #151 of 3408

sling... dont know what you have or have listened to but the o2 amp just makes things louder and doesnt add or take anything away from your source material or dac output.

 

if you play crappy tunes into it they will come out crappy tunes.

 

so make sure you get some reall great recordings to really see what this amp does NOT do.

 

All the best

Alex

I just got the O2+ODAC. I could not resist the price and hype. First, I was expecting something bigger. It's so small. Yet, it has a big sound. It really sounds like a desktop amp. Second, I was expecting bright and lean. But it's smooth, clean and not lean at all. Nice bass. Not something you get for something that resembles a portable amp. Really pleasantly surprised. I tried my JH13pro. Wow. Nice and smooth. Not edgy or hot like I expected. The bass finally came alive, something that only happens with a good desktop amp on these. I tried the Grado Magnums. It of course did not warm it up but it did not accentuate it either. It sounded smooth. I tried last my LCD-2 r.1. It no longer sounded warm and creamy. It sounded very neutral for the first time. At least to me. But overall. I am very pleasantly happy. I could not ask for more for such a low price and size. Very powerful transportable, amp/dac combo that more than satisfies.

 

edit: I still the LCD-2 needs more power.  This little thing is really powerful but I think the LCD-2 needs more to sound full and alive.

How does it compare to your Centrance Dacport? 

post #154 of 3408

It's so different.  The Dacport sounds like a Class A....which is hard to describe really.  Dacport has similarity with the Asgard which is a Class A amp.

The Dacport is really airy and the instrument separation is really great.  But what the Dacport lacks is fullness and body that comes with having some bass presence.

 

The O2 while neutral really has a sense of fullness, body and authority (bass presence).

 

The Dacport sounds like a good portable amp while the O2+ODAC sounds like a good desktop amp.

 

So I guess it is honestly like comparing a portable with a desktop amp.  Which is not a fair comparison.

Hope you can shed more light on JH13's treble and mids performance when paired with O2/ODAC.

Has anyone used the O2 with an HE-6?

I like the ODAC+O2 with my HD800 and LCD2 but I wanted to add a pair of headphones that sounded more alive. (Maybe an amp change...)
post #157 of 3408

O2+HE6?  I'm dying to know if anybody has paired the two, but something tells if someone has, the results won't be a surprise. 

post #158 of 3408

I believe even nwavguy himself would admit that HE6 is one of those rare headphones that O2 just simply won't power well enough.

Sorry if this question has been asked/answered already.... has anyone modded their o2+odac to accept 9v batteries? If so, is it working well? I'll probably house the batteries outside of the case.

If I recall correctly, some people did it by placing the ODAC board under the O2 PCB where the batteries are, so the batteries could be kept.

Its been done several ways, under the board, and in larger cases....dont remember anyone doing it via external....

Does the ac power need to stay plugged in in order for this to work or is it usb powered? It seems kind of awkward to have the power adapter cable sticking out of the front.

The O2 and ODAC are powered independently, regardless of whether they are in separate enclosures or not. The latter by USB, and the former by the AC adapter or batteries.

The standard, all-in-one O2+ODAC requires A/C power, doesn't it?
