If you go to this site you can check out either your own hearing or your system's ability to reproduce upper frequencies.

With a modified Stereo 70 hooked up to Spendor SA1's in my desktop system the best I could do was 12K
 
With The Bel Canto S300 substituted for the Stereo 70 I could hear the 17K tone! 
 
All my tests were done at the levels that produced 85 dB at ear distance with a 1k tone.
 
How will you do?
