Shahinian Obelisk vs VandersteenTreo


HI fellow ’goners.
I own the Shahinians, thinking of upgrading to the Treos. The Obelisks sound a little smallish for the room... And the room is not square, it's a big living area of a house, with access to the second floor's roof. 
Will this be an upgrade or just a sideward move?
Room approx 60m2, driven by Musical Fidelity A5.5, 250wpc at 8Ohm (thinking of replacing this one too).
Mostly jazz and acoustic music, less frequently - classical and pop.
Thanks!

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?

Why don't you just buy a Radio Shack SPL Meter off Ebay and be done with it? If you were closer, you could borrow mine. (Or, you could fly me to Russia. I need a vacation...).
Using the cheapo Radio Shack meter is easier and if you run into problems, we can help you. (Well, probably Johnny).

audio tools runs on my ipad...
what is unknown is the mapping of the microphone to the RS analog meter, IF I were home I could do this....

i would say use what you have as long as you can generate test tones on the Vandersteen EQ centers

remember we are NOT trying to equalize perfectly flat anyway just knock down the bigger nodes and fix cancellation a bit
