I suppose then that the fact that my tube amp, although a simple ultralinear design, has very little feedback and thus sounds crisp and accurate...transient impact and overall tonal accuracy seem spot on so I have no complaints. It doesn't hurt that my mid woofer speakers are very small and light magnesium/aluminum things that don't take much to get going, and the REL sub keeps up fine. I know this news is a relief for those who worry about my having a satisfying hifi rig, and that caring and compassionate wave of real love is palpable. Thanks....really...
