Ive recieved mine and i love it also

Ended up getting the silver one. Had to basically draw a card out of the hat to make myself buy that particular colour. Im just waiting on my new Ipod and Dock to test out its true abilties right now. Gotta look at selling my Petite also i think!

In reality, it seems the Boa may be an improved product, albeit with some compromises in raw power output for the sake of sound quality, size and battery life (double the battery life I think).

I can't come to any conclusions till I get 300 hours on it, and try it with every headphone in my stable. I made the mistake of reviewing the D2 Viper with 185 hours on it and with only 2 headphones, and then had to change my impressions when I had over 300 hours on it.

I guess you can still roll opamps in the boa though - as long as you use soic+soldering iron

while it is good nice cheap portable amp, it's BEHIND my pana ct470 pdcp player ( which sounds nice , search in head-fi about it ) as a DAC .
compared same songs side by side more then twice .

Amp do his job nicely , dac not so -imo .

The pana ct470 dac ( line out ) is lil more of all ... . more then lil deeper tighter bass , not boomy at all , faster ( funnier ! ) , airier . more separation , stereowider , sound picture clearer .. more joy .. all in all better comprehension of the music ...blablablabla ... . .

Don't know if the dac of the boa needs more then 150hr to develpe though .. lets wait

 

[boodi]

one thing it lacks is attack .. not to say that decay is good ..

sorry to be the one out of the choir.

As I said, the amp do his job .

want to wait full burn in .

I think you are right on the target with your comments! It is a slight overall improvement. You have also identified the only real "limitation" I have found in the little boa over the first 100+ hours. There was definitely a sacrifice in raw power to get the great sound coming out of that tiny package. I only notice it with phones that really need a major power boost, but I have to admit that once in a while I find myself wishing there was just a little more juice there. Other than that extremely minor limitation it is by far the best little amp for anywhere near the price.
One final note for anyone worried about battery life. The battery just goes and goes and goes. Pretty amazing actually.

Hello, maybe this would be the right thread to ask this question. I am wanting to burn in my new Ibasso d2 Boa along with my new Denon AH-D2000 headphone. What exactly is the correct procedure to burn in these amps along with the headphones. I have "Pink Noise" 22050Hz FLAC but not sure how many hours I should have this running. I want to make sure I don't fry anthing in the process. What would be the appropriate gain setting and what volume level should I have my output? (PC Speakers) Also should I also be worried about white and brown noise? Thanks.

 

[jamato8]

I just make sure the volume is no louder than what I could listen to. Also I prefer regular music to pink noise. I have used pink noise but find the process to go better with music. Many people have differing opinions with some believing there is no forming/burn-in period but many have also heard it, as I have, so I let a amp run while I am not listening to it. I have never burned anything from the phones to the amp when doing this. YMMV

This probably isn't the answer you want, but I would just listen to them and enjoy them.

That's a good answer to. I enjoy hearing the changes though I do burn-in some amps more than others.

Welcome to the boa lover's club!!
Over time you will have thousands of hours of enjoyment with you new amp.
"Burn-in" is a very subjective thing. Personally I have had many many audio components over the years and have yet to "burn" one in. It has always struck me as sort of like letting your new sports car sit nite after nite in the drive way idling to "break in" the engine. The audio signature of any sophisticated electronic component like a good headphone amp like the boa definitely changes over time and in most ways the changes are for the good.
With the boa you will note progressively more pronounced base and a deepening sound stage for example. Some people like to hurry up this "maturing process". I prefer to take my time and learn to know my new component as it settles in.
There is no harm in "burn in" except maybe a small amount of heat related wear and tear on the electronics but that is so small as to be insignificant.
If you are in a hurry, go ahead and "burn" away, otherwise just let the boa age like a wonderful wine and enjoy the process.

I usually listen to amps/headphones and leave them running with music on repeat when not physically there.

USB fed Amp/Dacs make it easy too.

This question only indirectly involves my boa amp but I really respect the opionions of several individuals who regularly post here so I am going to throw it out.
I have finally broken down and orderd the Senn Hd650s to fit between my Stax Lamdra Signature phones and my Shure Se530s.
I plan to replace the stock cable. Of couse my first thought was Cardas, but that was shortlived. I need about a 15 foot cable and to buy an actual Cardas would cost me about as much as I paid for the phones. I just can't justify it. So I am going to build my own. I know from other threads that you can buy exactly the same cabe that Cardas uses in bulk and I am pretty sure that you can actually get the connectors from Cards fairly reasonable.
So, two questions: First is it really worth it to replace the stock cable? Even if I build it myself I am still looking at $100+. And second, anyone have any hands on experience with doing what I am planning?

Well if you build it yourself I would really research the right kind of wire. Assuming that you would do this, and I only throw it out there because I haven't in the distant past always done that and wasted money, it is up to each person to decide if the improvement is worth it. From what I have read people that get wires they like do notice a change in transparency, detail and general impact.

Jam,
Thanks for the input. Your response was one of the ones I was interested in. I have done enough research to be pretty clear on the type of wire and connectors that I need. I can get the same wire that the Cardas employs for about $6 a foot. I will prob go ahead and try it. I will let you know how it turns out. I am actually a little skeptical but if I can do it for around $100 I will prob try it. Unfortunately once you start with serious cable mods where does one stop I wonder.
Since I am getting the 650s to mod, I am curious about your overall impression of the 650s. I am sure you have spoken to this before, so I dont expect a lot of detail.
Jackson Browne acoustic vol 1 and 2 are currently on my play and replay list too. Excellent music. I really enjoy the way he sounds with the SE530s combined with the little boa, and of course everything sounds great through the Stax phones.
