Shahinian Obelisk vs VandersteenTreo

Johnny,
This is plan indeed.  I just can't spend much time on this: I only see my family 2 days out of 7, and my wife is already jealous of the audio and forums :-) The two small boys are too.  So I am getting there, but just not too fast. 
Who is Jacqeline V? 
The previous owner promised to find those spikes. 

If I'm not mistaken Jacqueline V. is the person you will speak with when you call Vandersteen Audio.

Jazz
i understand
no stones just want you getting as Johnny said “ what you paid for”

now about the spl meter... my understanding is that Vandertones are compensated to adjust for non linearity of the R Shack meter

i have used Audiotools and a calibrated microphone with the Vandertones disc with ok results.

note also the analog eq centers are not what you typically see on an RTA as they represent typical room issues versus octave intervals....

so for best results buy a meter meter and download vandertones

Tom,
I do have a USB mike somewhere: bought it for some room-compensating EQ SW that I never got to using...
So I guest it night work out.
Audiotools works on a Mac?

"... guess it might..."
