What is this........midrange bloom??

I started back into high end audio about a year ago. Was able to get my system up in running initialy....after hours of breakin the new tubes(300B's) came up in my VAc70/70....Wow....I could sit on my sofa about ten feet a way...played the EMC Trio Medievel folk song CD and the energy engulfed my head....like a rush or ?. To make a long story short I purchased Vac 140's and switched my old NBS master speaker cable to longer Master IV's. To complicate thinks I have upgraded everything else....I do not have that wrap around your head thing anymore....this was a moderate high levels.

I recently tried a different digital cable fron my transport to dac and got a good hint of this sound quality....so I am know using a NBS statement IC from pre to amp.....After all the changes I still think the endorfin like rush was attributed too my old master speaker cables.

Is this quality....Bloom ?? desirable or is it over the top and actually a fault....My brother really liked the sound and now buggs me to find a way to reproduce it again.
