I have been told by Zach that the 2 set of pads are for pre orders only. The retail version comes with 1 set.
Didn't mean to put a full-court press on you here. It's just that ;you're one of the few (and first) people to comment in detail on the Atticus. If memory serves you heard both A&E in pre-pro form, not to mention tried various amps on each.
I like most of what I hear about the Atticus, but it sounds like getting an amp to really bring out its best means paying attention to "damping factor"--which isn't even listed for many amps in my experience.
Just checked the Violectric v281, and they actually do list it:
[COLOR=000000]Damping factor (Load 50 Ohm): 500 unbal. / 250 bal.[/COLOR]
[COLOR=000000]Problem is I don't know if even the lower number is considered "low" (+ the impedance they measure at is 1/6th of the impedance of the Atticus).[/COLOR]

Sorry for the confusion the two sets of pads was a pre-order special. I will add an option to add an extra set of pads at a discount on the order page. I will also update the website to make it less confusing.
Btw ... I like the Ori pads better
Thanks for clarifying that for me! I appreciate it. It's a bit confusing how the different pages say different things. Thanks!
At CanJam NYC I heard Eikon with stock cable driven by V281 and was surprised how great it sounded so it will have no problems driving Atticus as well

Oh, no worries at all! Like I said, I'm trying to figure out where this extra little bit of magic is coming from. I experimented with a 100 ohm resistor the other day with some interesting results, so now I ordered a 20 ohm and 75 ohm resistor, just to see what happens. I will report my findings.
The output impedance on the Vioelectric is 0.1ohm on unbalanced and 0.2 ohm balanced. That will result in a very high damping factor of 3,000 on the Atticus.
You can calculate the damping factor of any headphone and amp combo by dividing the headphone's impedance by the amps output impedance. In this case 300/0.1=3,000. The damping factor is essentially the amps ability to stop the driver from moving. Typically, a damping factor of 8 is sufficient for most applications, but higher damping factors have been shown to have an effect and several companies are big believers in pushing it as low as possible. But in some cases, dropping the damping factor lower (say, 3-6) can create a pleasurable sound (particularly with 300 ohm headphones).
I'm basically experimenting right now to see how much or how little effect this can have on the Atticus's sound.
That's no fun, thought I was getting 2 set per headphones as well..
I for one am glad you're doing this experimentation...though I can't visualize how you're actually using these resistors (is soldering involved)?
Either way, the whole idea of decreasing damping is surreal to me. I came of age in audio w/big jumbo audiophile speakers w/subs built in. And there, the big concern was increasing damping, particularly in the low-end drivers (by using over-built SS amps). Though I did use tube speakers for mids/highs, so perhaps I was ignorantly exploiting the higher-damping issue (or not).
I guess the whole headphones-as-little-speakers metaphor breaks down a little when it comes to a high impedance dynamic design that may respond well sonically to higher damping factors than most SS amps produce.
Headphone audio remains an adventurous path. Not everything works exactly as predicted.
I just bought some of these: https://www.ebay.com/itm/381662639828
It's just an experiment at this point.
Yeah, in most cases, I'm an advocate of higher damping factors as well. I use heavy-gauge DanaCables for just about everything in my system, whose impedance measurements in milliohms, so I'm a believer for sure.
But Grizzlybeast's post the other day reignited my curiosity about this topic on the Atticus... his experience mirrored mine so closely... so I'm going to play scientist for a bit and see if I can figure it out. I'm kind of a nerd like that.

Careful, you might end up with a $2 plug permanently attached to your ZMFs. Haha
