I own VR2s, they hold their impedance stable and high. therefore you can use tube amps easily. I used a Consonance M 100 Plus a 40 watt pp integrated. I currently use a Jadis DA-60 which is underated at 60 watts per. In any event use the Cary, I think yoi will like it . You can biwire the woofers with an SS amp if you want.
