Thanks for clarifying that. Your winky eye'd smiling face didn't quite do the trick and actually made it seem more to the jab in the ribs kind of gesture to me. My apologies for being a bit terse in the previous post.
No worries. I still need to tone it down a little. This is my first world community. I never really interacted on a forum before despite 15 years computer experience.
You said you noticed a "severe difference", but then you are suggesting that it may have been because you also got a new amp that you had not heard before...is that right? Would you expand on that. Sorry, I'm just trying to follow you here and may have missed a previous post. Nice choice of amp BTW.
Severe going from an RSA portable sr-71a. I assumed 100 percent of that was the amp. I had the d1 dac for 2 weeks with the portable before rev1's left driver kicked. Severe should ready immediately noticeable to my inexperienced ears. But if you read the peak reviews, they pretty much tell you it's an in your face amp. It's resolution is mind-blowing, the separation makes you feel you're on a stool in the studio. So I figured it was all the peak. But then the first couple Rev2 impressions mirrored my own. It's a different headphone. In my opinion, a better one for everyone but those who have a serious fear of treble and already thought the lcd-2 had more than enough. There is definitely more extension now. And some of the creaminess is lost. I couldn't get fatigued before. I can now. But I want more. I'm hooked! So like all things, a trade-off. It's a complex choice. It's not and never will be a "one is better" scenario. I can speculate that much 
It did not occur to me that WA "dumped" his Rev. 1 -
Dumped was the wrong word. Again, I need to tone it down. seems to me like he sold them to pay for the Rev. 2 and that he had enough confidence in his aural memory to know whether he liked one more than the other, and was willing to accept the risk (which amounted to a few hundred dollars). Some people just don't want multiple pairs of headphones, or multiple pairs of speakers (I certainly don't). As far as "getting all the info" before buying - all you can really get is the specs and other peoples opinions. None of that will absolutely tell you how YOU are going to like it, long term with your system and your music. The only way you are going find that out for certain is to buy or borrow a pair. You could also go to a meet and listen I suppose, but that can be of questionable benefit as far as being a gauge for long-term personal use. Anyway whether you think R1 or R2 is better, like everything in this hobby, will be entirely subjective. Indeed, I'm sure they are different if Audeze says so, and if they are using a different material to make the drivers from. I'd also take what Audeze says about the revision, the sound and their reasons for doing the revision, at face value and not speculate on alternative explanations for their motives, nor on how the sound may deviate from what they've presented. Lets hear from you once you've heard them (and I understand you have Kevin - just not getting the full story there, per above). They seem to know what they are doing and have maintained 100% integrity in all their dealings by every account posted here (I have not read a single complaint that lasted). Now really, why would folks like this start acting or doing business in any way that was different from how they've established their very successful business...especially given that their livelihood directly depends on this product? It's the same two guys at the helm.
I understand all this and my attitude about these guys is so positive that I'm saying a few of us may end up adding a used rev1 to our new rev2's. I wouldn't be doing this if I thought they were dishonest businessmen. I speculated that the rev1 driver couldn't make it as a production driver hence prompting the switch. I probably shouldn't have. I didn't understand the tone of the thread yet. But that didn't mean one or the other was inferior. My point, which I made poorly, is that it's going to be an A/B choice, not and Old/New choice. Which means good news for all of us. There's lasting value in every lcd-2. Because if they are all valuable, then there is the potential for a trade market among our community.
Pay no attention to that hamster at the keyboard.
