I may or not qualilfy as a basshead. I absolutely LOVE bass--but I'm referring to the quality and quantity of bass in all music, not just electronic. For example when the full power of a slap-string funk bass comes at me through the right headphones (or through powered speakers & sub)...bliss.
I did own the JVC-HZ1000's. The bass was mind-bending, but the overall sound wasn't (sold them). So maybe bassheads don't want me in their club.
Regardless, I have a bass story. I've been on a rampage lately, buying & selling headphone amps. The more I do it, the higher the price tags get (it's an addiction). About a month ago I got a used Violectric V281 headphone amp/preamp. It's quite overpowering in a Teutonic way--extremely composed/competent, every button & function known to man, yet not in your face at all sonically. But you could probably arc-weld with it.
Anyway...naturally it drives my headphones, even a planar, like it's a big fly-swatter vs house flies. The bass is ridiculous, wonderful, epic. But that's not the story.
The story is what happened the 1st time I used it as a preamp w/my powered speakers (Swan M200 MKIII's) + subwoofer (SVS SB-1000). I've set them up & fine-tuned to sound as good as possible on a wide range of music, everything from bass-heavy reggae to classical. It's a good system. After using 3 other headphone amps with it (all different sizes/designs/power outputs), I thought I knew what the system can do.
Until the V281. I listen to streaming classical most of the day, so after putting in the V281, I'm hearing this in the background and it sounds...very impactful & large (even at low volume). So I turn off the streaming classical, crank it to moderately high volume, and put on one of my favorite reggae recordings. KaBAM! Think I lost a couple fillings...and may have a hernia. The bass from this thing is INSANE. I don't mean "elevated" or "EQ'd." It's just all there. The entire bass range + lower midrange have incredible authority, impact, dynamics--like live music.
To check it out, I listened to recordings of demanding bass instruments, like string bass in jazz; marimba in jazz & classical. Everything is right where it should be, not hyped or distorted. Yet the music hits like a sledgehammer.
(I'm in love with the V281!!)
