 Wow!  At http://www.mouser.com, I'm surprised to see that their price of a MUSES02 is currently only USD $46.25, purchasing fewer than 10 at a time. http://www.mouser.com/search/ProductDetail.aspx?R=0virtualkey0virtualkeyMUSES02 The prices have come way down!   In November of 2013, they were on backorder at all of the reputable dealers in the U.S. I waited three months until mouser.com had them back in stock - when I then paid $75 each, plus tax and shipping. 12 Nov 2013...
 Yay!  I'm hoping you can justify my comments, but feel free to vilify me, instead!  LOL  It's so hard to be objective with this subjective hobby.   
Hi Scruffy1,   A friend of mine once told me he had read an article or heard a book or whatever that left him convinced of its message:  "Too many choices leads to unhappiness". I say, "The more choices the better," but when it comes to op-amps, I'm glad I only own one piece of gear into which I can roll them.  It sounds as if you've got several pieces with which to ramp up the permutations and combinations, as multipliers of your inventory of op-amps. You almost need to...
 Hi! Some people I've read are saying the SS3602 has a rolled-off treble compared to the Burson V5 and I have to agree it's a little bit less airy, but I really think it's also a cleaner, better-defined treble - not as (annoyingly) crystalline with the HD800 as when using the Burson V5, but I wouldn't say there's any loss of detail. It's like a big fan was turned on to suck the smoke out of the air.  When the smoke is gone, you can see better.  The treble difference is...
 It's a wonder more people here on Head-Fi haven't tried it, but the price is higher than the Burson V5, so that's a showstopper for some people.   Then again, I paid $150 + shipping for a pair of NJR Muses 02, ordered from mouser.com, to avoid getting counterfeits. When you compare the material construction of the Sparkos SS3602 to the Muses02, it's the Muses 02 that's way overpriced (and not at all competitive in terms of sound quality).   This IC op-amp costs $75.00 (if...
Scruffy1 has posted some very positive comments on the Burson V5i, in the Opamp thread:   http://www.head-fi.org/t/432749/the-opamp-thread/5175#post_12642543
 Thanks very much for your well-expressed opinion!  
In a word: Headroom.   A recording can demand momentary power levels that far exceed rms levels. If the headroom isn't there, you don't hear the full dynamic range of a truly dynamic recording.  It's not about how loudly the amp can play the music. I want an amp that can play the music much more loudly than I would ever want to listen, whether I'm using headphones or speakers.   Plugging an inefficient headphone directly into an iPhone, or worse, into a Sony NWZ-A10...
 Despite the efficiency of the PM-3, most DAPs and portable amps are going to fall short of providing enough power for the PM-3 to really become all that it can be.  If it sounds good to your ears on 30mW, it will sound much, much better on 300mW.  But, again, I think that once you get to around 350mW into 32-Ohms (I'm guessing on my experience with various amps), certainly no more than 500mW into 32-Ohms, you will have "arrived."  (The PM-3 has a 26-Ohm impedance, but...
 First, thank you for your appreciation of my dogmatic dissertation.  And to Peter (@peterinvan), who "accomplished nothing" by creating a balanced cable for his M8 > PM-3, I want to apologize for neglecting to mention that you should be congratulated for recognizing that no improvement could be heard!  You have wonderfully objective ears - especially given that you built the balanced cable yourself. I would surely have heard some improvements, had I built that cable!    I...
