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.

I would have bet a cheesecake that Mrtennis would enter this thread and point to bloom as a tonality affect. Some things never change.

In my experience, bloom has nothing to do with tonality. Bloom has much to do with the amount of time the fundamental note will last. The piano is THE test here. The texture of the note, i.e., its signature made up from a grouping of strings, can be discerned.

Does the piano note fundamental immediately terminate without any follow on harmonic decay? If so, there is no bloom. This is the classic failure of digital in its early years. And unfortunately, far too many line stages destroy this capability as well. No peaks or valleys in the tonality curve are going to make or break this characterization.

The other half of the picture is the harmonic overtones, the harmonic decays, i.e., the follow-on, of that strong fundamental note. This tends to be more about the system's low-level resolving capability to hear the sound diminish for a long time in a silent background. Without the bloom, you never get to this point. But a strong bloom does not guarantee the long follow-on.

Cables can indeed destroy such system capabilities, but unless you have electronics that can pull this off, cabling is not going to matter.
Wow sounds like virginity...lol. All is not lost I have my other preamp that I used when I had the "bloom" but the NBS old Masters are gone to the cable guy in the sky....Walter...lol. OK...in goes the old preamp..for *****&grins.
My own definition of bloom. since I have seen another, is similar to having a forward soundstage but particularly with transients. The sound comes out at you. "Aggressive" is a synonym but also implies bass transients. It's fun but annoying after a while.

Wow I was just looking at your system. I think you need larger speakers in that room to breath out a little bloom.

Just kidding here. I would go with smaller speakers, even a nice monitor speaker. To get that sound staging you like you will need to get them out from the back wall a little and toe them in will you.
