Actually, theres no amp that has no distortion. ALL amp introduces distortion. However, class A amp is biased higher so that it is conducting ALL the time. this means that even if there is no music playing, current still pass through the transistor/tube, hence lots of wasted power. The advantage is that there is no crossover distortion like in class AB or D.

Class AB amp has a pair of complimentary transistor/tube that conduct (more than) half of the wave form from each.

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

I can't make heads nor tails of the translation. If someone can read Chinese it would be great if he can confirm if the Cube F1 IEM is using Sennheiser HD600 drivers. I read it somewhere and then lost track of that part.

BBE technology stands BBE Sonic Maximizer, the promoter of this technology is the same name as the BBE company and the origins of BBE's also quite legendary. Back in 1961, BBE's predecessor Barcus-Berry Inc has been established, to 1985, BBE Sound Company (Barcus-Berry Electronics) was established, it establishes a better offer for the various fields of professional audio services to locate, followed by BBE Sound company has acquired a Barcus-Berry Inc and G & L Guitar (by Fender's founder, the legendary instrument maker master Leo Fender and the system of musician George Fullerton, Co-founder), which all the BBE resources into together. BBE Sound's M & A and the core team-building is not a traditional technology companies like "the technical staff get together up", but the technology and the actual music in close contact: in addition to a G & L brand, BBE Sound company's many employees themselves considerable level of player; Chairman John C. Mclaren has served as a Yamaha, CBS music department director or chairman, and he himself was a good pianist; the company's vice president of technology Paul Gagon not only experts in audio technology or a very talented musicians ... ... and so on to the professional qualifications of musicians and performers, along with professional and strong R & D strength, which forms the style of BBE Sound sound system: professional, rigorous, true and practical. And the final, BBE technology has become the most professional fields mainstream and the best audio processing technology solutions.





BBE is a sign of high quality --- AIWA IAUDIO many high-quality products, provided by the tuning BBE

Cool sound artifact than C30, from the BBE senior engineers carefully tuning adjustments, mathematical calculations, BBE's strengths, and by the human ear, and the tuner, allowing a more beautiful sound. Cool artifact than the C30 BBE host by BBE sent a senior engineer: TAKEO KUDO (Kubo husband)

C30 tuning process





Lossless music you hear is the combined result of repeated damage, the new BBE high-quality technology to enhance the non-destructive playback, a high-quality basis. BBE sound system to correct the harmonic losses caused by the delay and makes the sound more into clear and transparent, is not a simple balance control, but to improve the sound clarity, improve voice intelligibility level.

Why lossless music, is lossy. Such as FLAC / APE formats, such as music, the singer sounds from the beginning to the moment, after the microphone collection, the emergence of the first loss of the sound, the microphone by the music recording equipment recorded to memory, this is the analog to digital conversion, this is the second loss, to get the CD from your files, or APE / FLAC file later, through the audio signal may have experienced tens to hundreds of e- components, and these electronic components, especially capacitors and inductors features with speakers, the audio signal will cause the occurrence of small phase shift, this shift will usually be more high-frequency signals to reach our ears later, and since people ear's auditory characteristics, and feel the music has become more ambiguous uncertainty, and can not be that accurate to the person at the scene to locate the instrument, so will the third, fourth loss. lossless music you hear, is not destructive , is a very comprehensive loss many times. He has not become the basis of high quality

The BBE technology for audio signals will be offset to compensate for this part, therefore, sound, BBE treated with music, more clearly. This is the world's numerous studio, superstar, top record companies use the BBE sound reduction technology because of high

*giggles* nice pictures they use. Hahaha.


PS: I think they're just saying that the Cube C30 has no problem of directly driving the HD600. Nothing to do with drivers or what not. Stomach ache now, just took a glance through the article. Brb.


PS2: Seriously, just stomachache, I'm not going off elsewhere to do anything else because of the pictures.. >_>

yes that gal they use in the C30 advert is really cute!

oh ok. that prolly means the HD600 is not easily driven by wimpish mp3 players. it would need POWERFUL dap like the C30 to drive it! LOL

not just in love with cube c30 now, also the girl in the advert

Added on February 15, 2011, 6:50 pmi think the class of the amp refers to the method of the amplifier functions like how all the amplifier sifus here describe. the class A is not a rating system.

This post has been edited by beederbest: Feb 15 2011, 06:50 PM

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. )

for ur information

gumstick also can drive Beyer DT880 250 ohm or HD650 without a problem in volume.
Sounding wise?
ofc not perfect

I don't think perfection can be found even in a RM2K dap what more a RM200 one? Individual preferences in SQ is highly subjective. I've known gourmets who have such a higly developed sense of taste that they can tell you what were the ingredients that went into the dish but that doesn't mean they enjoy their foie gras more than I relish my hokkien mee.

Just to be clear, Rocoo-A uses a totally different hardware compared to C30 or Gumstick. Rocoo-A is Rockchip Nano based while C30 / Gumstick is Sigmatel based.

Older version of Gumstick actually sound louder because of the old firmware it used. New generation of Gumstick sounds softer because the max volume is limited to lower distortion during EQ - thus newer Gumstick is about as loud as C30 is going to be (the volume limiting already applies to it as well)


Also to clear things up, SQ wise the two are on par. I simply choose C30 because its has BBE.

Not owning a gumstick I am curious if the EQ settings on it is as interesting as the BBE on the C30?

ok lol... I got a question... shy to ask

what is BBE anyway XD
what does it do?

its from google translation so its not very good. if you can read Chinese go to the link provided a few postings ago. its some kinda sound technology like dolby... thx ... equalization ...etc

Just curious, is the C30 using BBE or BBE+? I'm asking coz the newer Cowon models (>S9) use BBE+

y not get one n compare it with gumstick?
who knows it might be able to drive them well too?

Added on February 16, 2011, 12:47 amcube c30 using BBE+ according to here.
