Northern Oak

Price revised.

Bump. Added W1000x details and asking price.

SOLD

Looking for a good condition DT880, specifically 600 ohms.

hi all,

Looking for HD650 and HD800. If you have one for sale, do drop me a PM. Thanks!

Instead of Airport Express, you could consider using Apple TV. It does have optical out and if JB, could double as streaming media player through XBMC. Think this way, the receiver dun need to be Airplay compliant.

hi all,

Looking for Denon D5000 and AKG K701/K702 (K701 found!). If you have one to let go, please drop me a PM. Thanks!

Regards,

how n where ya to do the decoupling?

Just look up LT1085/1086 datasheet. I had tried other caps, MKPs, electrolytics caps but found tantalum to have the most positive impact. Note that you may want to purchase tantalum caps with at least twice the voltage rating as what it is subjected to and take extra care with the polarity.

Note: LM7812 is replaced by LT317; Silver + MOGAMI NEGLEX OFC internal wiring; RCA phono jack out as preamp

I had very positive results using LT1085/1086-12V regulators with tantulum decoupling caps compared to LM7812 and 317. You might want to try out.

Have you tried Bluetin? They have this model listed in their Japan store.

hi kyaw,

Thanks for the suggestion! I have thought of getting from Minhwa but I thought his price for the SA5000 are not competitive enough, hence my hesistance.

Did you try Stereo? I remember it not available locally. I might be able to get for you if I'm dropping by Tokyo.

Thanks for the suggestion. I have contacted Stereo and they do not carry this model. I will keep your offer of help in mind, in case I cannot find a local source.

Any kind soul can point me to where I can find a pair of MDR-SA5000 locally? Thanks!

I'm looking for a well-maintained pair of Sony MDR-D66SL. If you have 1 to let go, please PM me. Thanks!

Found! Thanks to Mat! I'm getting back my old D66SL.

Hi guys,

 

Anybody know where can I find Yuin earphones or other Hifi gears in Haikou, China?

 

Thanks.

Might not be easy to find but you can try to search thru www.baidu.com, www.alibaba.com.cn or www.taobao.com. I usually find the shops through there.

Try Koba. They have brought a decent chassis from China recently.

actually i think i have spent more on photography than on headphones but i felt that spending on photog was more justifable a cost

 

and point number 4 -> i agree

Exactly! I had spent so much more on photography but the cost is justifiable. At least no one will disagree that the 85mm f1.4 has very nice bokeh, even after 30 days.

Wow, seem like many have already quit headfi. I left the headphone scene more than a year ago for various reasons.

1. I thought I have spent an excessive sum of $ on headphone stuff that cannot justify the costs.

2. It is a selfish hobby where only one gets to enjoy it at any one time.

3. I spend more time tweaking/changing stuff than listening to music.

4. The flavour of the month frenzy that sings praise of one component, only to be condemned in 30 days' time.

Moved to photography and never looked back. I'm still into audio DIY though, but only to fulfill my wish of DIYing an entire system, just for the joy of it. The material costs aren't high either, as long as you know where to find them.

The only headfi gear I left with is an ipod nano -> iBasso D2 Viper -> UM2.

No one ..........????

Ok, I start the ball rolling then. Here's what I have done.

Changed the silmic caps to Blackgates and Cerafine, I prefer the sound of Cerafine as it is brings in a sense of liveliness. Silmic to me has always been slightly warm sounding.

Changed the .1uF decoupling cap across the supply pin to 1uF BG non-polar and MKP 1837 .1uF polypropylene cap. Found this to be the best compromise.

Last but not least changing the default NE5532 (think this is used as buffer) to LM4562/LME49720. I had thought that the low output current for the LM4562/LME49720 might have some problems for me but it didn't, maybe becos I was using it to drive my UM2.

One thing to note. With this configuration, I find that LM4562/LME49720 does not response well to .1uF decoupling cap across the supply pins. Sounded too aggressive.

Please feel free to share your findings.

I've got one that's not in SG but it's recommended to me by a friend who's teaching electronics in a school here.

This one's in Malaysia but not too sure if the price's reasonable

Thanks, mouz! Will check them out!

hi all,

Anyone can recommend PCB fabrication in Singapore? I would like to spin a discrete regulator power supply board? Thanks!

Noak

Anyone has tried modifying the iBasso D2? Care to share what you have done?

I believe ppl there should be able to help you since the MO was held last Sept.

wow didn't know u r another shutterbug ..

maybe if u're free someday we shd organise a mini SGH photog outing LOL .. participants(as of now) are me, lekguan, kenshinx hehe

That's a good suggestion. Can pick up pointers from all of you guys!

Probably chip in a bit with something slightly off topic.

If you are using OPA627, look for Carlosfm's tip on how to decouple the 627s. You can find that at diyhifi.org. I recall having a small decoupling MKP cap between V+ and V- and then decoupling between V+ & Gnd and V- & Gnd. The important thing to note is to keep the wire leads of the caps as close to the 627 pins as possible.

I hear significant differences doing so for the OPA627.

N Oak: thanx!!

u r right ..

more into snapping nowadays, but I still keep a humble portable setup for music listening on the go. Would v much love to go back to the endless pit of headphone listening if fund permits in the future

ah.. mr Tee.. I've lost touch with him since some 2-3 yrs ago ...

no idea where is he now(he isn't here anymore is he?)

Rameish: damn!! how can u still remember them all.. applause

I've noticed cos' I beginning to move to photography as well.
