Thanks Doc...

I was wondering what the frequency limits of the test were, and hadn't found an answer yet. The relationship between sampling frequency and test limits is especially interesting. I'm only paying attention up to 20.000 Hz, since I understand that is pretty much a limit for all but the most acceptionally gifted listeners... and my old ears are probably only good to 16,000... ;-( .

I included the overkill response info in case it might be useful to the more experienced people here - and they could shed light on what I don't know or understand or even know to ask. As for the super-tweeters... I bought them for 3 reasons - They were such a great price I thought it best to buy them now... I enjoy experimenting with "rocket"-science kind of toys... and the ERTs support lower frequencies, since they are crossed over at 12 or 15 kHz, selectable (if I remember right). Even using a SACD I believe the original "master" recording is also an issue, since you can't duplicate what wasn't recorded in the first place.

I think the extra support for higher frequencies will be worth the price, and I hope it will help to create the spine-tingling experience I want.

Thanks again... Best Wishes to All... the Hermit
