A local dealer has paired the VR4-jrs with deHavilland 845 (30WPC), along with a Hovland HP-100 pre and Naim CDS3. The system was beautiful, playing in a room around 14 x 20. So, I don't think you need hundreds of watts. Perhaps, a little more power would have been nice higher SPL on some recordings. Made me wonder about the deHavilland GM70 (50WPC) paired with the VR4jr. So, don't count out some of the less 'powerful' tubed amps.
