Alfa100-you asked about the resistors. All I know is that the dealer--who is selling the speakers on consignment--called Wilson, gave them the serial number, and they told him there had been an upgrade involving different resistors. The dealer told me that Wilson then sent him the new resistors and he installed them. Sorry, I'm not technically very knowledgeable and beyond this I don't have any information.
Wilson Sasha 2 Pre owned?
I am now listening to 25 year old Proac Response 3.5 speakers with Audio Research tube electronics. Great speakers but I'm considering an upgrade. I really like the Wilson Sabrina but now have a chance to buy pre owned Wilson Sasha 2s in the low 20's. They are about two years old but cosmetically perfect, would include a 3 year warranty from Wilson. Also, there was some kind of resistor upgrade after these speakers were manufactured and the dealer would include the upgrade. The boxes/crates are not included. Looking for any advice on whether this seems like a good deal, whether the Sasha 2s would be a big step up from the Proacs and whether the used Sasha2s are a better choice than new Sabrinas (which would cost less). Have to decide very soon because there are others interested in the Sasha's. Thanks.
