We have all of the above in stock. At $20,000 pair US, the S4700 lands nicely between K2 and 1400 Array in both price and performance. It is markedly more dynamic with a less resonant quality to voices in the lower midrange and more linear bottom than the 1400 Array. It does not have the refined look or sound of the K2 though. It has a balanced sound overall, but a bit more forward in personality than the 1400 Array.
