@ Marty - Ah alas, if it's hard to find these used stateside then it might be near impossible getting them here - unless fate intervenes. There's some great gear available here, but their on the pricey side of things.
@ Hifihvn - That's a worrying issue! I am very sensitive to shrill and bright high frequency sounds. And well if its ultrasonic then maybe I can't hear it haha. Will have to investigate this. Given my 'allergy' to shrill highs some have advocated speakers with non-metal tweeters. But some say it isn't an issue. Will have to audition to decide. I guess it varies speaker to speaker and listener to listener.
