Re: [TenTec] Question for techies

It's like POLITICS, you can say anything and get away with it! Recently they 
censured Olberman for giving money to candidates, like you and I could, if 
we felt like it, and I don't, but then they had comments and lots of 
REPUBLICANS wrote all kinds of nasty TWEETS about the guy and his policy and 
can get away saying anything they want about an issue ! Sadly it is abused 
FREE SPEECH !!
I  have not seen any review, and that doesn't mean there hasn't been one, on 
DSP NR, notch depth, etc. and I do hear a lot of difference in DSP results 
and find my old outboard W9GR DSP's most always work better than the built 
in NR but I am 80 years old and my ears are shot !
