    Shure

    hi, understand that Ban Leong will cease as a distributor cum service ctr for Shure earphones. Is that to say Grandtech will provide after-sales services (eg, one-to-one exchange for faulty products within warranty period) with Shure products?
  2. lol. for sure i can't even listen to anything higher than 17kHz, even in pin-drop silence and volume cranked all the up.
  3. just curious, typically i see some manufacturers spec their freq response in excess of the theoretical limits, while i see some other quote the rolloff at 18kHz or thereabouts. are some designing their stuffs for dogs/cats while others adopt a more practical approach?
  4. hmmm, 100pcs is too much. maybe can share with another person.... can you PM me the place to sell? thanks.
  5. philips contact cleaner. works for me everytime to remove tarnished surfaces on RCA plugs & connectors. sidetrack a bit, where to get those rubber caps to protect unused RCA/3.5mm/S-video jacks from oxidation? hard ones i know SLT basement got carry, but prefer those rubber ones
  6. some tubeamps when powering the low-impedance headphones, (eg, 32 ohms or lower) are more susceptable to microphonics. at higher impedance not audible at all.
  7. Have her album, but somehow, listen for a while and chuck it aside most of her songs are rather similar, so quite diff to remember which is which....
  8. Try Norwegian soprano, Sissel Kyrkjebø... very nice. http://www.sissel.net/ or Eliane Elias, jazz pianist singer, similar to Diana Krall... BTW she's coming to town for a one-night concert at Esplanade One-night only performance Saturday 14 Mar 2009... $58*, $88**, $118 Concessions: Limited concessions for students, NSF and senior citizens: $40* and $60** http://www.esplanade.com.sg/whats_on/progr...lings/index.jsp
  9. By Mediterranea, track name is Andalucia, album name is Tesoro Escondido.
  10. inspired by the design at qables. at a small fraction of the price of the below PM u the parts cost.
  11. here is a picture of my DIY LOD. Thanks to Morgan for the tips on his website. Parts used iPod dock connector from SE Neutrik RCA connector 3mm black snakeskin iPod dock Y-splitter Canare 4-way & 2-way microphone cable some heat shrink tubings Silver solder Araldite epoxy glue all can be bought from one-stop SLT except the Y-splitter from Qables. use slow-setting (12-hour) Araldite glue to close up the Y-splitter halves & dock shells gives a very strong bond and dries clear. had great fun doing my first piece... will do a few more different ones... next one in line will be a 3.5mm stereo minijack to 2 RCA cables... hehehe the LOD cables connected to my tube headamp... ;p
  12. hotel costes not really cheap, nice packaging though....somemore won't really classify them as SQ cds... Boney James, Dave Koz
  13. I got a few of his albums... and his chinese works, the famous Yellow River Song...
  14. Lang Lang is also nice. his performance on Rachmaninov piano concertos
  15. the iTunes store is upgrading all their music to iTunes+ with higher quality (256kbps AAC) without DRM anymore. no more limitations on the transfer of music but they embed your email inside. so they can track and trace...
  16. SLT basement got one shop? the one selling batteries for cordless devices?
  17. would think jitter exists in all cdps, from cheap to expensive ones. question being how they are reduced. the report was quite dated, and advancements in digital audio tech have since evolved, so making it even less distinguishable.
  18. what i tink about your case here is, you shouldnt even be adding any resistors or doing any modding at all. why would you want to add a resistor in the input section to ensure that both your hdph play at the same loudness? power is wasted in the resistor when it can be better used to drive the load. also, if u do add in a resistor in series, and u attempt to crank up the volume more, there may be more snakes (hiss) heard thru the phones. the rated power handling of headphones is just a number. senstivities (dBspl/W/m) tells u how efficient the drivers are singing given a known applied power. some manufacturers will quote their sensitivities at certain spot-frequency. ceteris paribus, a driver with a sensitivity, say, 100dB/W/m plays softer than another with 115dB/W/m. this has nothing to do with the rated power handling. on the subject of over/under-powering ur headphones, there are equally contentious schools of thoughts... google is ur best fren, you can find the info there.
  19. adding a resistor in series reduces the current and attenuates the signal. it does not increase. if i not mistaken, impedance matching is such that the Zo of the output stage of the amp matches with the Zh of the headphone to gain maximum power transferred to the headphone. good headamps have this capability to maximise the output transferred to the headphones by adjusting the output impedance selector, which is typically a range of values of Z, eg, 8ohms < Z < 32ohms 33ohms < Z < 64ohms 65ohms < Z < 120ohms 121ohms < Z < 300ohms select the range that best matches the rated impedance of the headphones. normally it would be better to overpower the headphone rather than to underpower the headphone. that does not necessarily mean u will fry the cans, it just means u have more headroom (typically 6~10dB more) extension in terms of the reserve power. my headamp puts out a 2Wrms in the hdph out which far exceeds any rated max power of any cans. just that it's easier to drive even the most "difficult" cans w/o introducing any distortion or artifacts.
  20. can just go to http://www.itunesgiftcard.biz/ to purchase the giftcard, create a phoney US account, redeem the stored value and start downloading them The US Apple iTunes offer both standard 128kbps and 256kbps AAC format, though nowadays 256kbps is more widely available. Dun think they provide lossless format as the download times can be much longer than AAC. anyway, i feel that the SQ of AAC anytime beats MP3 anytime, given the same bitrate.
  21. yes, i am also inclined to think that way. while more pricey transports feature exotic materials used in the manufacture, sometimes i think they are very overhyped. in their product literature, they may smoke out those uninformed that the quality of the pickup/servo assembly is very critical in reducing jitter or whatever crap that can present as a irrecoverable error input to the DAC.... a cheap PC CD writer has far more capable error correction capabilities than those used in highend home audio transports. that is what i found out when i popped in one of my very old CDs that have undergone some serious laser-rot (many miniscule gaps when looked thru strong light) into my home CD player and it skips big time. when popped into my PC CD burner, it ripped perfectly!
  22. BOSE = Buy Other Sound Equipment x2 to that. sonically, BOSE sounds not high not low, in fact their jewel-cube satellites are overhyped. but some establishments are using their BOSE business music systems (i last remembered Paragon installed their white cubes in their mall). to spend >3k on 5 satellites, one music centre and one bass module is crazy where other makes can have it at a fraction of their price. but i like their RF remote that works thru walls unlike most IR ones that require line-of-sight.
