I know it's blasphemy here, but I think the subjectivists might be on to something with HE-6 based on their anecdotal power observations along with Innerfidelity measurements.   I agree that a large power reserve that is never used should have no positive sound contribution.   However, if...

For what it's worth, based on Tyll's measurements, HE-6 sensitivity (at least his measured example) seems to be more in the 77dB/mW range.

Quote: Look up: "WAU16-400".  Mouser links sometimes break, but it's the first google result at the moment.     It is the 16VAC/400mA transformer originally specified for use with "low impedance power hungry cans" in the O2 documentation vs. the cheaper 12VAC/200mA transformer...

It's probably only available through electronic supply houses (Mouser, Allied, Newark, etc).  The first google hit is Mouser.  The O2 Details page lists some other alternative ones too that might be available elsewhere.  Mouser is usually cheapest (even with shipping) when it comes to buying...

I posted in a response in the massive MD thread, but that'll get buried, so here:   If your HRT Music Streamer ii+ is anything like the non-plus version, it puts out 2.25Vrms. On AC power, the O2's maximum gain = 7 / Vinput.  So a gain above ~3.1x is going to overload the input and clip...

Quote: Objectively, I can't find the sensitivity spec on the MD website anymore, but I recall it being 92dB/mW back in the 840 pad days.  Extrapolating Tyll's MD power measurements for 90dB (0.52mW) gives me 92.84dB/mW.   Please correct me, Dan.

Quote: I've gotten about a dozen announcements/tests today so far from MrSpeakers.  I love the MDs, but I don't need to be told this many times.

I'd like to comment on extended time period comfort of the MDs (840 pads + comfort strap).   I put them through around 24 hours of head time in 48 hours.  And probably another 24 hours over the following four days.  I may actually be underestimating.   I had kept my HD598 (which I...

Is there a reason (other than the obvious) that the Mad Dog + Comfort Strap model shows being in stock on the product page, but when you add it to your card, it is out of stock?  It is taunting me. 

Can anyone talk about having seal successes/failures while wearing glasses?  I wear pretty average thickness plastic frames and wonder with all this seal talk if I'd have any problems.

Dibs, for what it's worth.
