Hello from Tampa Florida, USA. I've been to Thailand a couple of times and love the country, people and culture. And I've found the Thais have good taste in quality audio gear and music. I was surprised to find better audiophile stores there than most I've been to in the states. I also found plenty of CD stores with a large selection of SACD, HDCD, K2, Gold discs and XRCDs. Here I only find those via internet stores.
There has been a lot of discussion and opinions/theories/facts and experiences regarding speaker cables. You should be able to find a plethora of speaker cable threads from using the search function. However, it's been a week or two since we talked cables so maybe we're due for a fresh cable debate.
One thing most of us agree on is that room acoustics and even speaker placement have a far greater impact on audio performance than cables so my suggestion is to consider how your room interacts with the sound of your speaker. Once you have a well tuned room you'll then notice more dramatic changes between different cable types.
Welcome to the ML Club. There are a few of you on this forum from Bangkok so perhaps you may want to get together and compare notes someday! I hope to visit again.
