Here we go found it this morning while reading.
"The Treo works fine with a pair of Vandersteen subs. I used them that way for almost a year until I sold the Treos the first of the month. With all five of the amps I tried it with it needed to be run with one value lower than the input impedance of the amp.
To GreenGrass if you really like the sound profile of the older Vandersteens you really need to listen to the Treo before just plunking down now almost $7000 for them. They to me are much different than the "classic" Vandersteen sound of the 1,2, and 3's. I kept my 2CE Sigs boxed up the whole time I had the Treo and in the end prefered them. I have owned three different Vandersteens over the course of the last 15 years. If you like the "classic" Vandersteen sound you might want to look at the Odyssey Lorelei or the Nola Contender and pocket the significant difference. Or buy a used pair of 2CE or 3A Sigs. There are always ones on either A'gon or USaudiomart. Just my opinion and others may differ."
I thought I post the whole reply.
I guess this just goes to show speakers are like coffee, do you prefer dark or light roast, single origin or blend, store bought or home roasted so many chooses and we haven't even gotten to the point of whether you take something in your coffee.
Speaking of which I need to go get me a cup, it should be done brewing by now.
