I was just a "browser" in this forum without an account, but when I saw your write-ups I had to sign up! Am I one of the few, or the only one from Singapore here?
I saw the banner reading "......Zerogain visits Singapore....." and I thought it was an ad or something that simply pops out MY location, but on following the link, it's much more than that!
Small talk aside, how did you like your visit to Singapore Scott? Before delving into any equipment discussion, the thing that irked me (or caught my attention at least) was how you mentioned the retailers at The Adelphi were very "open" and customer-friendly? I would like the correct that--not so much to us locals if you don't look the part, mind you, I was an undergraduate student when I first joined the stereo fraternity and got my first proper kit (which at the time, sounded astounding to me, but I digress);
So I was shopping around in The Adelphi, and I definitely don't look like I had a lot of spending power, and what I received at 3 or so shops was enough to deter me from entering any others, in a nutshell, I think what you described as the treatment you get in shops in the UK was very much what I got: If you ask too many questions, and don't seem to be going anywhere/actually purchasing something, well it's unspoken but you will feel the heat in a minute!
That said, the shops I went to were mostly only interested in giving me verbal "summaries" of what they have on sale, and only one (which I entered) offered me the luxury of a sit-down and listen, and even then, I had a difficult time getting out of the shop or expressing my intention of "just looking around, checking out the gear (not buying)"
That said, I think you have to look the part (from a local point of view), a middle-aged person would have more cred and hence receive more preferential treatment than the teenager with a thin wallet drooling at the equipment;
But enough of the rant already, hope you enjoyed your visit and sharing with the rest of the folks on this forum;
PS: The exchange rate works in you guys' favour, but sadly does not apply to us locals, cheers
