IINM, gumstick also uses MAX9722 opamp. How does that affect the amp class?

Yeah, I never thought of class A as a rating system. Just wondering whether the type of opamp used could define the class of the amp, or is just a part of the circuit; i.e. how the opamp is used will determine the amp's class.

Looks like my previous post is a little confusing. Sorry. (and maybe this one is confusing too I guess. )

Hm.. since I don't really know where to start, I'll do it chronologically.

First I tried the F1 while waiting for file transfers to the C30. Tested the F1 with my W902; I guess my stand on it is pretty much the same as clieOS's. Personally Sony HPM-77 is the better IEM for me. In comparison, it's colder, better isolation, better transparency. Little lacked in treble when compared to F1, but with treble boost, in overall it's better than the F1.

File transfer and charge completed, I went on with trying the C30 with Sony MDR-Q68LW, my mostly used headphones. Thought I'd go with this since I use it most of the time.

The navigation pretty much is basic portable player. The only thing new to me is the AB and EQ through long press AB. Had no problem with it.

I was gonna compare the SQ on all players I have, but after turning on BBE out of curiosity, I just don't want to turn it off nor do I feel like using other players.

BBE is sweet. The first song I played with BBE is 'Brave Song' from Angel Beats! (both original and Gldemo ver.) and the sound is just, wow. Especially the vocal.
All of BBE presets to me is a hit and miss on different phones. As an example, with my Q68LW which somewhat lacks in bass but great mids and highs, the BBE fits. However with VIVA, the highs become too much, and the sound isn't fun anymore. With HPM-77 however, VIVA sounds great. So far I believe that there's a BBE setting for every ear/headphone.

Last thing I've to say is that as how I remember, C30 is better than Sony nwz-b142f and nwz-b153f. Both, should I say PMPs that are in the same class to Cube C30 in terms of size, and Cube C30 blows them away in price, SQ, stock earphone, and of course, BBE. (The only thing I prefer from the said Sony PMP is the 3 line browsing instead of 2 in C30, but it's not a big deal anyway. )

Oh yea, can't wait to use HD668B with this.

In audiophile terms, or should I say technically, you're definitely right. To me, BBE is better in terms of fun sounding and something different for the songs that I loved, but was bored with.

Apparently that's what I've heard from audiophiles.

Ultimately, to me, true enjoyment of music... Is that when we listen, we enjoy. Naturally, I won't be happy or enjoy the music just because I think it's how it's supposedly the way it's meant to be heard.

If you like EQ, then the all round should be BBE.

Though now, I have started using user set BBE, mainly to adjust bass amount and freq because to me the preset BBE doesn't suit some song that's already have a lot of bass.

Nice find on the BBE. From my experience on BBE with flacs; at the EQ selection, all BBE options except for BBE are gone. It's usable and gives a similar effect when used with mp3, but there's a bug. The bug I detected is triggered by:
1) Changing the track, either going next or prev.
2) Going to file browsing by pressing 'M' or any other options, except for the main menu.

The bug is where the sound some sort of went back to normal EQ preset plus a huge increase in volume, about an extra 7, without indicator itself showing any increase in volume.

Choosing any other EQ WILL NOT change anything,(the screen will keep showing the BBE, and the sound is still bugged).

Here's some methods that I found that disables the bug.
1) Re-selecting BBE will turn the sound back to the regular BBE. Also, from this point foward, selecting any of the regular EQ presets will have the usual effect.
2) Going to Settings -> BBE Setting -> ShutDown BBE. This works by bringing back the EQ setting back to last non-BBE preset used.
3) Going to Settings -> Sound. It will automatically return back to last used non-BBE preset upon choosing 'Sound'.
4) Sometimes, long press M -> Music -> Now Playing. It goes back to the usual BBE.

That concludes my finding.

P/s: Oh yea, when I went to BBE Setting under Settings menu, the only options left are the USERs and ShutDown BBE. Also, playing around with the USER will not disable the bug.

EDIT: Added some additional findings.

There are a lot that cost around rm20 or more, but IINM, a standard 5V 0.5A usb charger shouldn't cost around rm10..

P/s: A friend of mine bought one recently with rating of 5V 1.0A for rm19, at ALL IT. The 0.5A one should cost less.

Digital Mall@PJ Seksyen 14. There's one at lowyat too.

I've used FLAC files with bit rate up to around 1000 Kbps with the C30. Does that answer you question?

AFAIK, the limits on FLAC for this player is as what tunertoobe said..

Find a paper clip, use it to push the reset button.

From personal experience, you'll encounter *this from time to time. I even carry a paper clip around these days.

p/s: By 'this', I mean hangs..

IINM, the one that we get from beederbest is using v007.020 firmware. There's a v007.021, but from this source here, BBE MP, VIVA and others will be lost. Only BBE, and perhaps the USER1-3 remains.

Anyone tried any other firmware with the C30? Or perhaps players of this kind i.e. N2, Gumstick, C30 etc are all buggy?

p/s: I don't mind this level of bug. But it really bugs me when I didn't notice a self shutdown hanged, and left me with a drained C30.

I merely place the clip at a sim card holder in my wallet. Finally found a use for the sim card holder.

I still don't feel like updating my firmware, but let us know how it goes.

@ ClieOS: If only my unit would become stable on its own. Thanks for the share.

I have around 1GB free on the internal, no microSD used..

I used the user BBE to suit some headphones, mainly reducing bass or increasing treble on another. Though I haven't used the BBE ever since I bought the Eterna V1. It just doesn't work on most of my songs when paired with Eterna.

It's at the very first post of this thread. Not much of a search anyway. Cube C30 Impression by ClieOS. Almost for all criteria mentioned, he gave a comparison to the Gumstick.

I could give a summary, but I'm lazy myself.

P/s: I think this wasn't mentioned in the review. The price for a C30 is much cheaper than Gumstick. At least that's what I get from my survey.

No idea about the clock, but I don't use it. I've to set the clock every time I hit the reset button. Since mine hangs from time to time, you get what I mean.

TS is one of the guy. Look at his sig..

Now I know.. Thanks.

Are you sure a pen tip can properly push the reset button? I've tried it before with a regular 0.7mm ball pen, it kinda go in, but not deep enough to actually push it.. IMO, a successful push is accompanied with a firm click sound, or something like that..

This has never happened to me before, so that's all I can help you with..

Means it's great for the price right.

AFAIK, it should be louder. Personally using the 007.20, so I can't exactly say what 007.21 BBE should be. Can you use USER BBE? You can adjust the volume gain there in USER ones..

P/S: Btw, you mentioned display bug. Meaning?

I see. Anyway, whether it's louder or not, normal and BBE has a very different sound, so, despite of what the display says, you should be able to tell whether it's on BBE or normal.

Just my 2 cents..

A new mystery to me. I've no need to pause to change EQ, period.

I wonder if you're using FLAC? Well, because if I'm using FLAC + BBE, I have to set me EQ every time the track changes, cause every time the track changes, I'd enter an unknown EQ mode where things just sound so wrong.

More on the FLAC + BBE bug that I know here.
