If you're lucky, you could ask a few singaporeans if they could lend you their tralucent 1p2. I demoed one by meeting w it's owner. Also, do remember in SG there is K10, mentor, se846 etc, be sure to check local stores to see which place is best to go. Btw you can demo NT6 at null audio.
I am in SG and yes there are all sorts of TOTL IEMs for demo at various local stores (except for 1plus2 or the new upcoming Ref 1 from Tralucent Audio). The different stores kind of complement one another in the range of brands available, i.e. if one store does not carry the brand you are looking for another store will most likely have it. Seems to me the stores here have some distribution agreement/partnership with the various brands.
Jaben - has almost every IEM/CIEM/CANs (probably the 1st place you want to check out) - JH, FitEars, Etymotics, Ear Sonics, Vision Ears, Sennheiser, Fostex, Abyss, Byerdynamic...
Treoo - Noble Audio (only place with 3/4/5/6/8C/K10 for auditioning), Fischer Audio, LEAR...
Stereo - Carry the more mainstream universal IEM/CANs, e.g. Sennheiser, Fostex, Sony, AKG, Audeze, Bose, Grado, Fischer Audio, JVC, Shure, Skullcandy, UE, Westone, etc. Sole distributor of Unique Melody and iFi DAC/Amps.
Connect IT - Similar to Stereo. Tends to selectively carry the newer latest IEMs/CANs as well as many ALO products. Only deals with universals, no customs.
AV One - Sole distributor of Audeze latest LCD-X/XC. You cannot find X/XC in the other above-mentioned stores.
I am not sure if there are other prominent audiophile stores for IEMs, so if anyone from SG knows can also chip in to this.
