hello, unless you're getting the ones over 15k, i will never consider yamaha because the tones are kinda muffled, i'm not sure you know what i mean. but that's just a personal preference..
personally i use a 2nd hand standing richard meyer one (the higher type, it's german+korean brand, sorry don't know much, but it works fine for me), been using it for about 10 years, when i bought it it was about 4-5 years old and cost about 2k. for this sound quality it'd probably cost about 10k on yamaha's side. anyway i think 2nd hand is good. i bought mine at a shop at katong along tanjong katong rd i think. but sorry it was so many years ago,i can't remember the name.
