Here it is with the Mad Dogs.  I haven't taken any with the ADs yet.  These deserve a much better camera.

i watched the initial headfi vid again..

http://www.head-fi.org/t/676095/mrspeakers-alpha-dog-revealed-the-worlds-first-production-3d-printed-headphones

its inevitable for Zowki/n many of us to have keen interest in how open the soundstage is, since it was supposed to sound "like an open can".

The question begging to be answered of cos is the degree of opennesssss..

when does it breach the magic delineation from CLOSED TO OPENED in one's mind :P

(Zowki's use of the hd600/K701 is a reasonable midtier comparison i submit..a good hurdle to gauge.)

 

Jude also mentioned that he had  only the ef6 n mjolnor on hand to test then, both v powerful/balanced amps,

so i wouldnt be surprised he heard some BIGBIG sound from those combo in his loft... :D

BIG enough for him to be very excited during that preview.

 

Maybe the AD can use more JUICE, lets wait for other reviews to get a better feel.

Mmm just saying if he was concentrating on the soundstage all the time which it sounds like from the review... then any differences in soundstage would be more exaggerated then if he was just listening to the overall sound. If I sit there and concentrate on soundstage then it seems a lot of more obvious than if I just listen to the music.... Bit pointless me saying this because I have not tried the AD so maybe he is right.... But if they are even 80% of the HD600 and K701 for soundstage then that is impressive for a closed headphone. Think I might skip the AD anyway and get HE500 or LCD2 because I like powerful bass.

I per-ordered the Alpha Dogs eight weeks ago and they still haven't shipped (their website says it should take 6 weeks).  Their customer support seems really bad too; it took them over a week to get back to me the first time I emailed them.


It is being compared to two headphones that are well known for being very comfortable.

I tried to listen to the headphones as a whole instead of concentrate on soundstage but the soundstage was the difference that sounded most obvious so I couldn't help but make a note of it each time.

 

I can't say they are even 80% of the HD600 and K701's soundstage, more like 50%. They are not open sounding at all.

In what way is the O2/ODAC lacking? They have enough power to drive almost any headphone except for obscure stuff like the AKG K1000.

Ha ha - this is your opinion obviously, and may be the case with the 02.  However, it seems the folks that's liking the ADs are using them on different amps other than the 02.  

 

I'm using mine on a speaker amp.  The sound is grand, open, nice and airy.  No not like an HD800 but not 50% behind it either.  Yes - I would say on my rig 80% of the HD00 is about right.  I'm still not sure how we come up with these percentages.

42.7% of all statistics are made up on the spot.

Oh yeah, I keep forgetting to ask, are the Alpha Dog's Alpha pads any different than the Mad Dog's Alpha Pads in terms of overall comfort? I think mrspeakers said the Alpha Dog's are a little thicker at one point.

 

And then, how is the overall comfort of the Alpha Dogs [without the comfort strap]? I've tried my friend's Mad Dogs and I'm not sure I would be able to wear them comfortably for a few hours as they were quite heavy on my head (if I tilted my head forward, I felt like they were going to fall off my head; a good indicator that a headphone is too heavy for me).

Comfort without the comfort strap is bad. There is too much pressure on the top of my head.

The Alpha Dogs are rather heavy and have a lot of clamping pressure. Comfort isn't great but it's ok. More comfortable than the LCD2/LCD3 but less comfortable than just about everything else.

Oh whoops, I think I got my terminology mixed up. I meant to say comfort without the "cushion strap" add-on. I didn't realise the "comfort strap" is the thing mrspeakers uses.

It's called a headband cushion. Without the headband cushion, it is uncomfortable for me.

===============================================================================================

 

 

Lorspeaker...replying

 

o2 : Max Output (33 Ohms): 613 mW

 

ef6: Max Output: Class A 5W at 50 Ohms

 

 
Schiit Mjolnor

Maximum Power, 50 ohms5.0W

Maximum Power, 32 ohms  8.0w

 

i think it goes something like this as above....technically i am a zero...copied from respective sites.

 

-------------

 

For me,  i just look at the size of the metal casing...bigger n heavier = more powerful   :tongue_smile: 

My audioGd Nfb10 puts out about 6w i believe..in balanced mode the soundstage expanded 32.9765%

post #59 of 124

log(6000 mW / 0.29 mW) / log(2) = 14.34

90 dB + 3 dB * 14.34 = 133.02 dB

 

That's quite loud.

 

 

log(613 mW / 0.29 mW) / log(2) = 11.04

90 dB + 3 dB * 11.04 = 123.12 dB

 

That's still quite loud.

 

I'm pretty sure the O2 more than enough juice to power the Mad Dog 2013 according to Innerfidelity's sensitivity measurement, and more so for the Alpha Dog provided it's more efficient.

 

 

Protect your hearing; don't listen to music too loud.

there is a certain power level at which a can goes from closed to become open...

like a plane hitting the sonic boom n running free  when it breaks the sound barrier,

or battlestar galactica going lightspeed.. ok just musing...can some scientists help?

 

my denon d7000 just sounded crazy good when i hit it with 40watts. ..warpspeed i guess. hehe.

i know there is loudness from my ipad too..but its diff. dunno y.
