Headroom Overture Initial Impressions

The unit hasn't had a chance to burn in yet - it only has about 20 hours so far on it, but some initial thoughts after listening to this all weekend:

Old Rig
iPod -> SR-71 -> Sensaphonics 2X-S

New Rig
iHP-140 -> Overture -> SR-71 -> Sensaphonics 2X-S

The iRiver/Overture is a definite improvement over the iPod's lineout as source, but the sonic signature (at least right now) may not be to everyone's liking depending on your rig. The magnitude of the difference is similar to the difference in listening to the Sensa's straight out of the iPod or putting the SR-71 into the mix. In other words, maybe not a huge "night and day" change, but a definite and meaningful improvement.

Its strengths are in its presentation of detail.

The usual statements apply - I'm hearing a 3-dimensionality to the attack and decay of cymbals. Harmonies and instruments are being more clearly defined and brought forward, so I'm getting the "wow, I didn't hear that before" effect. Though if I go back to the old rig, I can listen for it and hear it, but it's just not as there.

There is more presence in the music, especially in the upper-mids (female vocals) and treble. I hear the vocal technique of female vocalists just a bit better.

I've commented before that the Sensa's are actually laid back, especially compared to Sony high-end headphones. Actually, I've been looking into UE-10's to get a less laid back sound. The iRiver/Overture has satiated my craving for detail (at least for now). I'm getting a bit more of the detail that I get out of my Grace m902+SA5k combination.

Some of the downsides:

Bass is muddier. It's there, but just not as controlled as the old rig. Also, maybe I'm just spoiled by the "velvet glove" control over bass of the Grace m902/SA5k rig.

The new portable rig isn't as smooth in its presentation of the additional detail as the Grace/SA5k. As such, it is brighter rig and I am feeling listening fatigue (for the first time out of the Sensa's) as a result. I find I am turning the volume down a bit. I can still enjoy the music, but honestly, I miss having my music moderately loud.

I wonder if the Coda might be a better match-up in this respect. But that's the topic for another post. Either way, we'll see how the sound improves with burn-in.

Battery life - as mentioned by Tyll, the Overture eats through one of the 9v's a lot faster than the other. I haven't measured the life of the batteries exactly, but I've already swapped the batteries twice this weekend. Rotating the batteries, as discussed by Tyll, helps a lot, but needless to say, this is a powerhungry beast. I need to get some Plainviews (anyone know where? Esp. as Norm's gone now.)

Anyway, these are really "initial thoughts" on a new (i.e., not burned-in) unit, so take them at that.

Best regards,

-Jason

I agree that the detail is good. This DAC chip in general is high performance and I've heard it other implementation.

I don't think the bass is muddy on the Overture but could be the amp's fault.

I think the Coda is a bit punchier at the moment and has deeper impact than SR71 but it's highs is a little bit too edgy for me at the moment.

My units need more burnin also. I'm one day more burnin than you

What?????? I had to google this. WOW.
http://www.headphone.com/layout.php?...tID=0010030400

Limited release. And only available for purchase with the Coda Amp for $600.

jjcha and Ian keep us posted on your futher impressions. I am currently looking into acquiring a DAC.

Maybe this should go in the Amplification boards? Whatever, there is also from AOS Electronics the FLUTE DAC/AMP (you probably already know) that is like the Overture, but the FLUTE does not have the Computer USB source connectivity capabilities either.

Hmmmmmmmmmmmmmm.

Thanks! & Keep us posted.

check the NYC impressions thread - a ton of folks got to hear the coda/overture in action today in NYC!

Was gonna order the stack on Friday, but called it off. Seems like a waste when I already have the AOS Piccolo.

As for Plainview 9.6Vs, you can get the Maha PowerEx 9.6V from thomas-distributing.com, it's pretty much identical to the Plainview 9V. I sold my set of Plainviews however, and bought a box of Duracell Ultra. Couldn't stand recharging batteries, even if it's only a 2-hour affair for 4 batteries.

I've been using the Maha batteries with good luck. The same fit issues apply as they're longer than standard 9V batteries. I've had bad luck with Duracell Ultra's leaking.

Cheers,
Jamey

The AOS Flute is both a DAC and an amplifier while the Overture is just a DAC. You could compare the Overture+Coda to the Flute however.

Or Overture + any amp. Of course you'd still have to buy the Coda amp though. The beauty of separate means you can choose your sound.

I find the DAC of Overture better than that of flute though.

Of course this is an option, though like you said you must buy them both. Quote:

And the beauty of together is that it is one unit and much more portable.

You have directly compared the two?

You have to add an external battery pack to the flute so it is basically also 2 units.

Yes we've compared at the NYC meet yesterday.

I can vouch for that - the Flute would need a batt pack to go on the go, while the coda and overture can house batteries internally. the overall size diff probably would be negligible - both are pretty small and would fit nicely in a camera bag.

There are other things to consider with two separate units such as interconnects. Also, as you pointed out both the Overture and the Coda take separate batteries and while the Coda has a battery life of 20 hours, the Overture only runs for 8 on batteries. AOS has stated that the battery life with his own battery pack is 30 hours for the flute. I suspect that it is longer if anything with my PowerRunner. I will do a test from full charge at some point to test the battery life with my setup.

In any case, I moved my questions about the comparison to the NYC meet impressions thread so I won't thread crap here any longer.

I plugged the Overture into my work rig:

Old work rig:

iPod -> Denon UD-M31 -> B&W LM1

New work rig:

Desktop computer -> USB to Overture -> Denon UD-M31 -> B&W LM1

Wow. The work rig isn't anything special - it sounds pretty nice for background music and the occasional sit-back and enjoy a song or two. More importantly it's small and looks clean and modern without being too "slick".

But with the Overture in the system, there's this increased air between the instruments (I think I finally understand what "air" means) and it's actually starting to sound more like real music. The level of improvement is, again, similar (though maybe a bit lesser) than when I added the SR-71 to my portable rig.

Don't get me wrong, I don't think this little setup plays anywhere near the big boys, but it's nice enough that the sound coming out of it is distracting me from work.

I really had my doubts that the Overture would be that much better than just an iPod's lineout. I've always liked the iPod feeding my portable and work rigs. But there really isn't any comparison - HeadRoom's got something really special with this little unit.

Best regards,
