In the past, i used to visit Panthip Plaza a lot, also some stalls in front (inside what i believe it is a kind of mall, in a way connected (?) to Indra Regent Hotel), where i looked for computer/phone repairs and spare parts, etc, and also for audio replicas (specially on Panthip Plaza ground floor.
I believe Phantip Plaza is "dead", or already converted in something else. The vendors in front, are they still there? Where is the best place to look for audio replicas (or not), not so expensive?
