I've heard an s-9 in my system, although only for a few hours. Good bit of kit, and a proper Kondo Audionote too. Should be fine if the price is right (as always.) If pricey borrow a step up from Music First...I use one and they are seriously classy. I'd like to hear one against the big Kondo, both are likely to give you a great performance (SUTs seem to me underrated...not least because there are loads of cheap ones about, some fine, some not so fine!)
