    Peak impedance in dynamics is usually around the resonant frequency, somewhere in the mid-bass. Impedance always decreases below that point. I believe the Tee Wun peaks at 1000ohm or something like that.

    Yeah, so change the frequency values in the example as needed. I've seen speakers peak in the treble region in the distant past. But yeah, a quick glance shows something like the HD800 peaking at 600ohm around 100 Hz. Anyhow, point being, with increases in amplifier output impedance, the frequency response deltas are magnified.

    You can read the wiki articles on damping factor to get started; but in general the higher the damping factor (headphone impedance / amp output impedance), the better. There are schools of thought that we should at least have a damping factor of 3 or 5 or even more to get best performance. Low damping factor may result in a softer spongy sound or softer transients.

    For T1 or many Beyers, I don't like super high damping factors like 100 (amps with near 0 output impedance). Beyer headphones can have a bit of a metallic timbre and treble sharpness. A softer less dry / tight sound suites them better. 16-40 ohm output impedance is what I like to see. The Elise is on the upper end of that. The Valhalla 1 had about the those output impedance numbers (low / high) gain and I really liked the Valhalla 1 with Beyers. Ultimately it's a little subjective.

    So this guy says he already heard the ZD 3 times, but he needs to get in Craig's or @Marvey 's head about it? Or has he actually never heard the ZD or ZDS and wants to hear the difference for real? I hope the fire marshal is there in case he causes an arc fire or something...

    You know, this is the real issue with Head-Fi. People make crazy claims, with no real head time to back it up. Its actually not a Jude bash, but a community bash. I still like reading there, but one better have their BS detector on and well tuned before believing anything.

    Are there any good threads there to read? Last night I went and unsubscribed to all threads that are exhibiting gross displays of lunacy. But now I'm left with no threads. LOL

    Regarding the Elise Alchemist, I know there has been a ZD - but I don't think a ZDS - at a few HF meets in the distant past. There was one at the Massdrop meet for sure. He wanted to come to my house and take my ZDS to a more recent meet when I was unable to attend. I had never met the guy, so it came across as an odd request and it didn't happen. :D

    Thank you for your post.

    Looks like that's settled then, Elise it is :)

    Hello friends - hold onto your skivvies and make way for the next TOUCH WOOD breakthrough.

    The thought crossed my mind how the Sennheiser 650 stock cups are also compatible in the 6C33C-B top hat dampening configuration, which is also compatible with the 650 stock driver foam as a power tube treble softening adapter, so I thought I'd roll the dice. After some initial perturbation... SCHLONG! But just like an earlier astonished prophet using this word, we are referring to the infinite CHUB, one hard to grasp... well the sound was so amazing I had to come up with a few ones:

    FULLY ERECT, RIBBED, PULSING,THROBBING, AND ABOVE ALL OMG I NEED TO CHANGE MY PANTS!!!

    DRIVERS: Miniwatt 7308 SQ in Dewey Decimal Double Penetration Configuration (featuring white and green hot tap, mutual satisfactuary encoded copper wiring)

    POWERS: Tung Sol 5998 Unisexual configged, supported by the gentle touch of the Third Hand in open cascade, hot mirror triode follower. Mirror carries 566.7VDC, grounded in in an open wye, yellow/red 6N OCC wire to GEC 6080. The GEC placement between the two rectifier tubes is also key... Only semi or partial is accomplished if the placement is incorrect. I can not stress this enough.

    Folks, I'm an amateur carpenter who has built and auditioned many sound stages in my house throughout my life... Mostly for amateur productions with consenting adults. I've tried thick ones, I've tried hard ones, I've even tried soft soundstages. I've tried slippery ones, hairy ones, dark and light ones... Skinny soundstages, thick soundstages... Even the occasional muddy one. But I have never heard a soundstage like this one in my entire life at home. The holography of the stage is as if you fully locked and beamed a jungle alien from a far away galaxy directly into your pants. This made EVERY hair on my entire body stand on end, vibrate erratically, and promptly fall out. I spent weeks vacuuming up the mess. Better than the Felix Audio Fur Elise mk3 (and I've heard it 1.5 times - once at a meet with June from HypeFi, and another time when I was rolling some purple cray cray Kool-Aid pretty hard, so that's the .5) 16"/10"!!!

    Now that's funny right there! I think, though, that you have the jumper colors confused; shouldn't the yellow one be plaid? Seems to me that plaid jumpers
    have a more erotic midrange.

    Power tube treble softening adapters, as he mentioned. He rolled the dice on those, but it sounds like it paid off in spades.

    Ok thanks. I may buy two 40-foot container of those for my HD800 SD. However, I will need to find dice to roll... sigh, this is never ending.

    And a new king of trolls has been crowned...

    I'm sure that setup never arcs, ever...

    I want to stay at an arms length from the tube rolling "discussion."

    That being said, I would have returned the amp had I not changed the driver tubes. Perhaps I got 2 duds. Perhaps my ears are defective (my mother seems to think so).

    Changing the tubes saved me tons of grief. That being said, now that I have a sound I love, I feel no need to try any more tubes.
