Belles 150A HR...is this the 150A Hot Rod amp? The Belles should
provide plenty of pure clean power to drive the VR4s, although the 150A
Reference is the better amp. What tubes are you using in the Belles pre?
Honestly, I'd look at your speaker placement first. This can have the
most profound impact on sound. Describe your room size, and
placement of the speakers...distance from rear and side walls...distance
to listening chair...distance between speakers.
