Doesn't sound like the dragonfly is supported by the Pandora.

 

Dragonfly is cost effective because you can't beat it for it's price. They use and need to pay for the async stremlength license, do a 64 position dig controlled analog V control that will be more accurate than a pot. It's also not 'buttons' but whatever controls the V on your source computer. Incorporates 2 dedicated clocks, has seperate regulation and has a real warranty.

 

I suspect that the Halide is better for a little more but it also doesn't drive headphones.

 

It looks like the Pandora uses a polar tantalum 330mf output coupling cap off a likely inverting TPA6110a2 so there will be some bass roll off with low impedance phones. I don't consider this a big deal or indicative on the overall sound but I think it should be noted. Of course, bass will now become undesirable, LOL

The Dragonfly is working just fine. And seriously, do NOT do that. Mind your own business. I'm new to the Pandora AND Linux so I don't know how to do everything myself and have to ask. Don't post it here to try and make me look like an idiot.

 

Edit: Misunderstanding. My apologies.

 

I haven't exprerienced a bass rolloff with any of my headphones, low impedance or otherwise. If anything the Pandora has better low extension than most of my devices.

Yet you're so sure about so many technical things. How about you don't do that. I was checking out the Pandora and happened across your thread that said the Dragonfly didn't work. Glad you got it going. It was posted in a public forum.confused_face_2.gif It's the World Wide Interweb, get used to it. I wasn't looking for you but the subject matter and asking questions like in that thread in no way makes you look like an idiot. This thread wears less well. A 330MF cap will already be down 3db by 30hz into a 16 ohm load. Like I said it's not that big a deal if you're careful and/or it's good besides but it is what it is and saying otherwise won't change that. I have players that I like that do the same with certain loads but then, I don't make claims about their bass prowess either.

we need some 470uF Capacitor fun, so we go down to 21hz :D, but it is bigger... and probably will not fir in the case

post #349 of 364

The calculated pass frequency is already 3db down so even 470 is marginal. I know since it's what I used in an amp project because it was the largest silmic II I could fit. I'm not as opposed to stacked aluminium or tantalum as some are but I didn't find them as good in this use. You could use a 1000mf 6.3v tant and it would likely fit. It's a bit close to the rail voltage but it would take a complete chip failure to stress it and that point you're repairing it anyway. Tpa6110a2 isn't a powerhouse anyways (150mw max). The gentle roll off is less of an issue than most may think. I do believe that frequency response, while important, is generally overstated. Just some info and isn't a bash on the unit. It can still sound VG with these parts.

The review is almost done, just have a few things left to revise.

 

As a little teaser:

 

"The Pandora absolutely smoked the Dragonfly in the side-by-side testing. I was very surprised and pleased. The Dragonfly has more output power, but that is literally the only thing that it has over the Pandora. The Pandora has greater resolution and clarity; the Dragonfly sounds smoothed over in comparison. Both are clean, controlled and expansive, but the Pandora has a lot more detail and texture. Using my Sony MDR-SA3000 with it is an absolutely unbelievable experience."

Wow, I'm very surprised and pleased also!

 

Maybe our darling Pandora does have a valid claim to being a top-notch portable player, then, considering all the rave reviews of the dragonfly.  Good work, mweston!  :)

 

Prediction: some sceptics will doubt your neutrality or competence to judge this!  haha, well even I am doubtful ...

 

All ye head-fi'ers might want to read this review of the Pandora's audio while you're waiting with baited breath as I am, for takato14's full story...

 

It would be good takato14 if you can post the review on buchse aka pnd.to/box, our new blog for Pandora tutorials and reviews.
You can talk to zLouD on IRC aka büchse on the forums to arrange it...  Or, I can post it for you.

 

I think we're almost to the point of being able to prove our thesis ...

that the Pandora actually is the kick-ass-est integrated portable off-the-shelf player thing in the whole damn universe (at least, for less than megabucks)

 

edit: this goes into my sig, here and elsewhere :)  quote of the day, by a long way ...

My friend is lending me his HD600 and his RS2i, so I'm going to hold off on posting the review until they arrive and I can have some time with them and the Pandora. Sorry for the wait. Bump for now.

post #353 of 364

well update to this thing, I think me and takato14 is the only two person who own this hardware

as of today for some odd reason after I copied music to my pandora , rockbox STOPPED completely in its attempt to build database , then commit suicide and auto closes

just a report

You might've ran out of space on your SD card, that's what happened to me. I had to remove a couple songs.

 

However then I just deleted the database because it was including sound effects from games on the SD card, and I find that my organization is more to my liking.

 

Just a few last changes and the review will go live sometime tonight. It'll be in the OP and posted as an actual review, might be a delay on the latter as I'll need to add the product to the list.

The problem is solved by making deleting rockbox app data,  my sd card were not full at any rate,  i still have at least half of it empty
