Its curious that the shop master seems no nothing about this machine. May be he's a marketing people. Everything is secret.
SRC is not without its merit. Some DAC has this optionl. Cplay can select output rate.

Till now I did not have the best experiences with SRC but I am open for new insights. I will evaluate the device: when it sounds good to fine that would be nice. If it sounds mediocre to bad, well I get used to that when I buy ready made stuff 🙂 If it sounds excellent I would be done with this hobby.
Abraxalito, the silence is deafening. How does it sound now ? It should have changed by now I guess.

You are really a happy man.

I'm not playing with it at the moment, working on an amplifier project now. I doubt I'll be bothering to listen to the analog outs much - did you note that I hadn't checked the tone controls were set flat for my first listening experience? So that rather invalidated it - I had not twigged they existed and would be set randomly on first powering it up.
<edit> Incidentally, while on the subject of tone controls I did a quick FR sweep and it looks like there's a substantial bass roll-off with my assumed 'flat' bass setting of 08. By substantial I mean -3dB at 100Hz roughly. Definitely I'd advise checking out if this is down to the DSP or perhaps the output coupling caps - I am driving a fairly low impedance of 2k. Since the output caps are 2.2uF I reckon this should result in -3dB at 36Hz so it looks like its not the caps.

You have a chance to make a bit perfect SD player.
¡¾ºìоµç×Ó¡¿FPGA ¿ª·¢°åÒôƵģ¿é /I2S¸ñʽ / CDÒôÖÊ/ ¶ú»ú·Å´ó-ÌÔ±¦Íø
FPGA audio module RMB59.
Read WAV in SD card, out put I2S.
PT8211 (I2S audio format) + PT2308 head amp + volume control
Must buy with development board:
RMB680.
EDIT:
Sorry, not sure if the FPGA coded, or just a board let you code the FPGA.

Complex development board + bare board without case + time needed to understand and program = never ending story
Interesting suggestion - thanks. But its a .wav player and I already have the QA550 to do that. My preferred solution for an SD card player would be FLAC implemented on an ARM CPU which hopefully will be much lower power than an FPGA, as well as being considerably cheaper. An FPGA strikes me as major overkill 😛
Considerably cheaper is very important. I don't understand why no one make a SD player module, just like the remote control module.
Back to the board,
It confirm that come with 2 DVDs sample code. It may not precise enough. The problem is that even you willing to pay for a high price bb101 plus, who knows if he just use the sample code without debug?

Interesting!In the transport, a microcontroller of 8bit 8051 architecture, C8051F316 12MHz, with specially developed firmware reads a WAV file on a MicroSD and sends the data to VLSI VS1053b codec chip.
Its VS1053b based. The thread may bave some strength and weakness of this chip.
If you read further down the thread, the VS1053b was only used in the first incarnation of that player. The next generation ditched it in favour of an FPGA.
Charles Altmann has done an ARM solution - its also expensive (very expensive for the components used, but he has a substantial R&D investment to amortize) but nevertheless a work of art : THE ALTMANN TERA-PLAYER
Very nice project.
This is an all in one wav player. Its use spdif in internal traffic.
For the price, I will look for this

Yes, its considerably cheaper but not as cool looking - and that display is way too small. But I think it won't sound as good because its using a S-D type DAC (WM8741) rather than a multibit. But perhaps it could be upgraded to use a TDA1387. Do you know what its using inside?
The bbp-100? I only know it use WM8741 and a FPGA. The bbp-n100plus has large display, but using dual WM8741, not your taste.
Have you seen the new QA660?
When will jean-paul receive his sd player?

Yes I looked at the QA660 on Taobao before I bought the HiFi360. It looks to be at least 100% overpriced. But this version seems a bit more promising : QLSǬÁúÊ¢ QA660 »ðÈÈÔ¤¶©±¨Ãû£¡-ÌÔ±¦Íø
My player has finally been packed for shipment yesterday. After that I got a kind email telling me that the menu is in chinese only !!!! I will try to arrange for a translated version translated to english/german/french/dutch. If the factory is willing to cooperate that is.
Even if it would be the best sounding portable device available: it is plain ugly and far too expensive. For that price on can invite a live band ! And it lacks a display which is normal for an Ipod but not in serious HiFi. I don't think it will be successful on the market as who will be the buyers ? Not MP3 Ipod lovers as it is overpriced for them. Serious enthusiasts will not accept the drawbacks IMO. I hope i am wrong.
edit/update: just got an email that the factory will change the menu to english.

Yes I spent some time looking through all the menu options for an English setting - never found one. I shall have to ask my gf to tell me what they all mean 😛
It seems its not too expensive (nor too ugly) for a fair number of Head-fi guys. There's universal admiration for its SQ over there even though the price is clearly off-putting for many. It does take a certain chutzpah to ask that much money I must admit - but compared to some other high priced stuff, this product by all accounts delivers the goods.
