Don't walk but run over to Audio Asylum and look at the Quick Silver Mini' monos that are there for 800 per pair. These are great tube amps and are rated at 25 watts and should drive your Vandy's. This will give you a real opportunity to experience what tubes can do and a nice pair of amps to build around in the future, if the itch drive you to do so.
I'm in the camp that encourages you to explore hi fi in any direction you want to go, whether it is tubes, analog, digital, victrola or a banana peal. Hey, this is really a fun way to expand your knowledge and find what really tickles your ear.
Enjoy!
