The Mad Dogs have a good soundstage for a pair of headphones that isolate so well. Only to be surpassed by the D7K, TH-600, TH-900 with regards to closed-backs.
So.... The fidelio X1 were not really as good as I was expecting.... Now the question is, do I get the good ol' HD600 which I already know I like (except the lack of sub bass and slightly slow sound) or do I try the Mad Dogs.... Hmmmmm decisions. I do think the soundstage on the HD600 is just awesome and I do not want anything with a small soundstage.... Are the mad dogs bad in this area?

Did you try the Alpha Pads on the TH-600 / TH-900s?
If your source provides a standard 2Vrms to the O2, 1x and 2.5x gain is perfect for the Mad Dogs. In this situation with these headphones, the 6.5x gain would be useless. I only use 1x with the Mad Dogs and the volume level has a ton of headroom to reach staggeringly loud levels. Now, if you have any headphones with 300 ohm impedance or higher, you might want to consider the option for 6.5x and 2.5x.
You could always go with the 6.5x and 2.5x option and see how it works for you. It is very easy to clip the resistors out of the 6.5x signal path to convert to 1x if that gain is too much and not very useful with your equipment.
I think it says here it supports 2.5 output voltage? I'm not sure what to make of this spec list.

I only used 2V as this is typically considered the standard for the maximum line out voltage.
The difference between 1.6V and 2V is really nothing to be concerned about.
20*log10(2V / 1.6V) = 1.94 dB difference
Your onboard audio should be perfectly fine to use with the O2. The O2's default gain of 2.5x and 6.5x should provide plenty of power for the Mad Dogs to perform optimally.
I have not yet, but am planning on doing so. At the moment I'm trying the stock Denon pads on the TH-900. Unfortunately, the sound is not to my liking. I will try the Alphas soon (if they fit).
I think they will. I put Alpha pads on my D2000's and fit fine. Assuming the pad mounting ring is the same (which I shouldn't do) but if so, they fit well and are awesome pads.
Make every day a fun day filled with music and friendship!

So this is where the MD thread went...I had noticed recently the lack of news from the old thread in awhile, which I used to check every day. I was just too lazy to get sub'd to the new thread. Did I miss anything major?
