Vandersteen Treo vs 3A Sig as upgrade

I had my local dealer hook up a pair of Treos to demo them and left with a very mixed impression. I like the overall sound. They have a smoother, more refined and sophisticated midrange that the 3A Sigs can't match. I want that. But the bass was less defined and the top end was bright. The sibilance was very exaggerated - this was with CD. Is this the character of the Treo? Thanks!

@mr_m If you do go with the X-2 at first, do you know what impedance you would need based on your power amp?

Hifiman. No, I don't. they showed me the type of meter I have to get to measure this. The guy at Stereo Unlimited said he could help me do this over the phone. I have a Rogue Pharaoh integrated amp.

I'm very late, but a cheap meter is a phone with a calibrated mic ($25) and app. On android I use sound tools.  It's very nice, and has much better extension than most SPL meters.

Also works with Room EQ Wizard if you get fancy.

@mr_m  I have the M5-HP adjustable Vandy crossovers.  I have two 100k ohm X-2 in mint condition if that would happen to be the value you need .  I was just looking at your integrated online but could not find the input impedance listed.  You would want an X-2 that is roughly 1/2 the input impedance of the Rogue.

You can halve an impedance by putting a resistor in parallel with it. :)

So if you have 100k but need 50k, put a 100k resistor across the inputs.

But really, this should only be for passive line level crossovers. Any active crossover should deal well enough with anything over 10k.

Best,
