Tube Rolling - No Change in Sound

In my Wyetech Opal pre, I substituted NOS Ken Rad VT231's for JAN Philips WGTA's in the input stage, expecting more body and warmth to sound based on Ken Rad reputation. But nothing has happened; I perceive no audible difference from the switch in tubes! What's up with this? This was my first foray into tube rolling.

>>I still STRONGLY maintain that the sonic signature of any system is at least 85% determined by the amp and speakers.<<

IME it's difficult to assess the performance of either component without consideration of the other. The same analogy can be applied to tonearms and cartridges.

That being said, I believe that speakers have the strongest influence on a system's sonic signature followed by sources not the amplifier.

YMMV
