Personally, I never understood the attempt to find "synergy" between an amp and headphone. Why do I read so many comments about folks who have a bright and crisp headphone and then they try to warm it up with an OTL amp and EQ?
If your amp is neutral with low output impedance, then you're free to choose a headphone that sounds right to you out of the box. This is why I like the O2 so much
EQ is a pretty useful tool. I wouldn't dismiss so quickly.
From a practical and economic point of view I think the best way to find "your sound" is to start with the headphones. They have more affect on the final sound then all the rest of your hardware combined. In theory the DAC and amp are just as important but in practice the variation between different models of DACs or amps is almost always miniscule as compared to the differences between of headphones so excepting models that require unusual amps like 'stats or the K1000 and HE-6 always pick the headphones first. Even if you have an unlimited budget there are only so many models of headphones to choose from so finding one that's perfect for you out of the box requires a lot of luck and you might need more tweaking.
Next I'd try modding the headphone since the mods will "follow" the headphone and affect its sound from any source. Depending on your skill, confidence, and budget (not many people will want to try and mod expensive flagships) you might not be able to get satisfactory results. I think its still worth mentioning for those with an adventurous streak.
The next step is software EQs and DSPs but they aren't a panacea either. Even if your computer is your only source they don't "follow" everything perfectly as they're usually set up in a single program and not "system wide" affecting everything you might play. Despite that limitation I place them here because they're usually free or pretty cheap. You can spend thousands on name brand professional mastering VST plugins if you want to though.
After that I'd try hardware filters, EQs, or DSP boxes. They can be used with more sources than a purely software solution but often they're more expensive and aren't as customizable so I place them after the software types. Example of these such as crossfeed circuits and tone controls seem to be the most common and accepted of these sorts of tweaks among the head-fi community. The Smyth Realiser is now making a strong case for hardware DSPs as well but its price keeps it a niche within a niche. Hardware EQ boxes seem nearly unheard of on here though.
Only after all that would I consider looking for "synergy" between a headphone and an amp or DAC. Clean and neutral components take many variables out of equation and give you a blank slate to create your desired sound. As the Objective2 shows they can be a lot cheaper as well. Even after factoring in a large budget for professional VST plugins or hardware DSP boxes you'll likely save as compared to something like a TOTL tube amp plus a tube rolling budget.
Of course your preferences might actually lead you towards a "synergistic" DAC or ampin the end even if you try all the other steps I listed. No off the shelf product I know of will replicate the sound of a specific amp and unless you're
Bob Carver you probably aren't going to be able to do it yourself either. There are other factors besides the just the sound that some may consider as well. Besides practical features I think tube amps just look amazingly cool. It's only the fact that making one which sounds as clean as the O2 would be monstrously expensive that keeps me from using one instead.
In the end what you like is what you like (assuming it's actually real and not just in your head anyway) and there's nothing wrong with that. I just think that from a cost perspective jumping to a new amp or DAC to change the sound usually be at the bottom of the list of things to try. There are plenty of people here who don't have to worry about that sort of thing and can pretty much buy whatever they like. If you know what you're getting into then go right ahead.
What I hate is when newbies are given the impression that you have to spend big bucks on a DAC and amp for a good headphone to sound better than a cheap one. The endless, "oh its your amp/DAC no wonder you think audiophile headphone X sucks" sort of comments around here convince people to spend money on things they don't need or want. Even if their DAC or amp really does suck that's probably still not why they don't like headphone X. The sort of differences most people in this hobby care about are tiny on an absolute scale. They get blown out of proportion on here and some people keep spending money on upgrades waiting for a revelation that never comes. For the most part plugging a new pair of good headphones straight in your iPod is the biggest revelation you're going to get. If someone doesn't think that's worth the money then they sure aren't going to think the smaller improvement a better amp may bring will be worth it either.
This wandered quite a bit, and most of it isn't really even directed at palmfish, who I quoted, but I felt like a rant today for some reason...
