From the Orchid photo, the 'bokeh' doesn't look pleasing to me... http://www.kenrockwell.com/tech/bokeh.htm

good snap N@Z

For headphones, I found my Grado RS-1 is the best match for the MuVo N200. RS-1 gives the best bass and treble. I think it is because MP3 tends to cut the high frequency during compression, that's why bright headphone is a good match for it

Interesting technology Curious how it sounds

I have this small player for 2 days now. A pretty small wonder. So far I'm satisfied with this player in general. I still wish some changes though I will cover it later. I had a 'not responding player' problem before, but solved with firmware upgrade. So don't forget the firmware upgrade if you buy it. As an MP3 or WMA player, this small player performs very well. Overall sound is good for such a small player. Some people said it sounds better than iPod, but I don't think so. It sounds about the same as iPod when playing MP3 (320 kbps, I didn't try WMA). But it offers more functions than iPod (Line In recording, FM radio, FM recording, & voice recording) The sound quite neutral, the bass a bit weak and less punchy. But it is compared to my Panasonic PCDP SL-CT810. For a player powered with 1xAAA battery, I have no complaint, just boost the bass a bit with it's custom equalizer (yes it has custome eq), then the bass sounds pretty decent (bigger but still less puchy). The midrange and treble is fine, neutral and enjoyable, pretty good for such a tiny player The supplied earphone is average quality, weak bass, a bit dull treble, with a bit dominant midrange. But quite listenable and neutral. Anyway, I never use the supplied earphone anyway. I use this N200 with ATH-EW9. I like the way they create the menu, it is simple and fast enough for a player with only a few buttons. No problem with it, I didn't even read the manual to operate all the functions The Line In recording is amazing The quality is very good, with selectable MP3 bit rate: 96 kbps, 128 kbps, and 160 kbps (the highest). The FM radio do the auto scan very fast, and the FM quality is good. A very nice feature (compare to iPod ) The FM recording is just average, not high quality, ADPCM format (.WAV) 16 kHz 4 bit, fixed. The voice recording is my only complaint, ADPCM format (.WAV) 8 kHz 4 bit, fixed. Poor quality voice recording, sounds muffle, good enough to record personal note, not good enough to record lecture, when the lecturer is a few meters away from the recorder . Only sufficient for close distance recording. I wish Creative will give a higher quality FM and voice recording, make it the same quality and format as the line in recording The battery seems last long enough, still full after a few hours listening, will try with 900 mAh Ni-MH later Compare with iPod shuffle, this player is more expensive (around SGD 300.- for the 1 Gb. I bought slightly less ), but offers more function, and.... DISPLAY ..... Yes 'display'... I can't imagine people can live without display... With 1 Gb memory (around 994 Mb usable) I can store around 7-8 CD albums in 320 kbps MP3 quality Good enough for me. Highly Recommended mini player, for those looking for flash base (more durable than harddisk), very light and small audio player (like me ) And don't forget the AAA battery, that means you don't have to worry about the 'end of life' of those propietary Li-Ion Battery in a few years down the road

My main concern as 'headamp DIYer' is the line out. Most of the flash / harddisk base mp3 player don't have line out. iPod can have line out only if we buy the dock. While most PCDP have line out. If you want music library, harddisk base would be the choice. For those who use it for exercise, and look for portability, I would say the Creative Muvo N200 should be on the wish list.

Aahhh.... it's been quite sometime since the last time I loged in Been busy with other things, and my office notebook spoiled... but it is a good news, because it means I'm getting a new one hi5, I have no experience with McCormack amp, so I cannot tell which op-amp suitable for it. And it is also depend on you music taste. What is lacking for you with the current AD71? Nice work tropicalrips And,... Happy "belated" B'day !!!

Great Job aaa! Well done! Waiting to hear more about it from you

Good news Jason! Probably later you can share to us the PCB maker info in Malaysia What is silkscreen?

I haven't received it... still waiting for it from Huangyong. Will PM or email you later when there is any update

Thanks Heady! Happy New Year to you and all forumers here Hopefully can have sometime for learning and experimenting new things in this new year

Aahhh, very nice tool! Thanks Heady and Tropical! I think I'm gonna get one too

Wow... high quality components for you first homemade amp... cool !

Well done aaa!!! Really deserve AAA rewards Very compact and tight spacing Knowing your attention to detail, you must have planed the layout very well Looking futher for the amp in the casing

Hi, it is ok! If it can be usefull for anybody else I'm happy Quite busy during christmas season, no time for hobby So far no plan for the dual soic yet, I bought some from Digi

I a-b'd it with my amp which used the Jung's Multiloop circuit like the Pimeta, my amp sounds a tad smoother. But considering the components differences (pots, etc.) and the cost, I would say Jason amp (my modded version) is really good for the buck

No rush..., thanks Huangyong!

Tube... tube... tube... the beauty attracks a lot of DIYers But I don't like the cap on the output Which most of the tube amp use... So when Huangyong become tube expert, you better try differential / balance tube amp... no cap, no transformer on the output DC coupled tube amp... that's cool Just sharing a little bit about my recent experience with tube..., Recently I bought a 4th hand speaker (I'm the 4th owner ). When I tried the speaker before I bought it, in the previous owner house, he used multi thousands dollar equipments to drive it. 80 watt/channel tube power amp, seperate transport and DAC, etc. After I bought the speaker, I brought it to my friend house, and we drove it with mid end equipment, Rotel RA-1060 integrated amp, and Rotel RCD-1070 cd player. Both cost less than 2k. Guess what, listening to the same CD, Emi Fujita, Camomile, I like the Rotel better than the multi thousands dollar setup I don't know how to explain, but it just sounds more neutral and easier to listen than the tube amp. Well everything is about taste, lucky me, I'm quite happy with solid state That's make my life lot's easier

That's cool Tropical! Your amp built like a tank But I think the transformer orientation better be turned 90 degrees to reduce hum My2Cents.

Interesting Tube should be my toys next year

No, around S$ 5.- only. I bought one from Farnell

Farnell has it. Try the search Or can get some sample from National

Cool! Congratulation! I also want to see more tuber from sgheadphones

Very nice B&W effect! The fake grain also nice and artistic! Great shot and post processing

Well, for 32 / 16 ohm headphone user, I think A47 with gain 4 is overkill. I agree with av98m, the simple CMoy is good enough for it Anyway, the Jason A47 circuit is working fine, only the ground channel need modification
