Re: Sierra 1 NRT upgrade vs supertweeter
If your main complaint with the S-1 is they are too laid back and you want a little more zing in the high end—something more like a metal dome but less fatiguing—the NrT upgrade is indeed the way to go.
Back when they were pretty new, some lunkhead did the NrT upgrade and wrote a fairly detailed review that you can find here:
