O2 AMP + ODAC - Page 116

post #1726 of 3410

Too bad...

 

I've heard a few people say the MSii+ is better than the uS, but I've also heard some say it's better than the ODAC too, which is part of what makes me curious to see how close these two really are...if the uS could rival the O2/ODAC in a portable package, I wonder how many units they'd sell overnight XD

I do have a HRT MSii+ Asynchronous USB DAC and the ODAC and it are very close, hard to tell any real world difference.

Have you ever heard the MSII? I bet the MSII+ must be like a 10% improvement over the MSII and even more transparent.

I wonder if there are any more DACs under $300 that get close to the ODAC sound.

 

So far i've only heard two..

LinusTechTips has just done an unboxing and review for the O2 AMP+ODAC:

Have anyone compared BCL (lehmann black cube linear) to O2 for HD650?

I'm really pleased with it thus far. In addition to taming the bass bloat on low impedance cans it also reels in the sibilance a bit.  This is really an excellent product.

Congrats on your new amp....yes it is an excellent amp for headphones....

 

Enjoy

New user of O2 as well. I was looking for a transportable amp to drive my HD600 and Mad dogs. Hope I will enjoy it!

Make sure you newbs come back with your impressions. I like to hear how people adjust to their new equipment.

post #1737 of 3410

Since i built my O2 i have also built a CMoy clone, Grado RA-1 clone, and a JLH Clone and although they all have their own distinct character and pros and cons the O2 is the one that has become my reference point that i judge all others against.  And to be honest none of them even come close to its level of transparency and detail.

 

Same story with trying out different headphones or cables, i can never really say what their strength or weakness is without running them off he O2.

 

I often wonder what will happen if i build a high end solid state amp, will the O2 remain the reference point, or will the better amplifier become the new reference point?

mcandmar....

 

I found the O2 competes with and bests many amps costing a lot more ......

 

While there are really some great amps out there they cost more, but also have a better build quality, in that they are built to last forever, like the vioelectric

amps, better switches and jacks... also better or nicer ergonomics.

 

That said the O2 as it stands is right in there as far as audio specs, and transparency...etc

 

I think you will be pleasantly surprised in your journey...

I've found this the case too, but I haven't really tried anything over $500 yet.

 

I'm surprised it held up so well to my Headroom Micro Amp + Astrodyne PS. I mean that amp was originally $350 and another $60 or so for the power supply.

 

The O2 is the closest i've come to it's sound. They basically sound the same or extremely close. I actually think the Micro Amp sounds more transparent but maybe we're talking 99% vs 95% :biggrin:

 

I actually prefer the O2 to even the E9, Asgard 1/2 and Magni, but not the Micro Amp.

 

Sometime I'd like to compare the O2 to the Leckerton UHA-6S MKII. That thing is $280 though and not $120.

 

If I had anything to complain about with the O2, there is not much. I wish it's treble was a bit smoother with the Q701. It's still good and much better than the Magni's treble though.

 

My Micro Amp sounds like a more refinement O2 with all the rough edges taken off. No need to pair it with specific headphones and it's perfectly with even the brightest headphones.

 

I sold the O2 to fund an Asgard 2 purchase (which I hated). No clue why I did that..in the end I just ended up with a new DAC :confused_face(1):. Should have just kept the O2 since it was for my bedroom setup.

I was stupid and wanted slightly smoother treble. We're talking like a 3-5% improvement for long listening sessions! Can you say nit-picking?

 

What I like in an amp is for it to work well with them ALL and not be only good for specific headphones. The O2 is basically that. Well as long as it's not like super power hungry like an HE-6 or whatever.

Funny you should mention the treble, i know exacltly where your coming from as i've actually had two, the first was bought ready built, the second i sourced the components and built myself looking for that last bit of refinement.  I basically followed the alternative kit list in the BOM with better Panasonic electrolytics, Wima film caps, Dale mil spec resistors, DD opamps, gold plated dip sockets, gain resistor sockets, red/gold pcb, and a few other tweaks like rear mounted RCA inputs and power connector.  The 2nd one ended up being that little bit smoother, and with a little less harshness in the high frequency's.  The difference is subtle, but enough to be noticeable.  Worth the effort if your considering getting another one.
