Stage 1 or stage 2 uaed alone makes things worse, both in a different sense. Believe me, I tried all possible combos as I had 4 pairs of TH-900, one unmodded to compare with and three pairs to experiment with, one I modded step by step. Stage one mods need the deeper cups (Lawton or not as I discovered with very deep cups of my LaLaNo-7000 (as I call it).
Agree with this statement but in the end it's the combination of the mods that does it. To be clear I mean dampening, deeper cups and thicker, angled earpads. The cable is optional but adds detail. How much detail? Depends on your hearing I guess, for me it was like turning the water tap wide open.
For me Dac-amp combos didn't bring out the best of the TH-900. A nice dac of your choice paired with a Zana will.
If you really want to go the Dac-amp route the Marantz HD-Dac1 does what you descrbe best. It isn't a perfect solution but it does what you are asking.
And it costs half of what the A8 originally costed. Not sure what prices for it are these days. Just don't buy it simply because it is of the Fostex brand as well and assume that therefore it will give you the best results. The Marantz does exactly what you describe and does it very well. The only reason why I wouldn't recommend it is because i heard better with my separate amp and dac.
EQ-ing (by soft- or hardware) will always give you the desired results. I'm not a fan of it as in both situations you alter the signal and I love my signal put through as unaltered as possible. It sdoes do the trick though but I choose for a good dac of my prefernce and a good amp of my preference to get the desired result, which I do get. Makes one wonder though, my more expensive solution alters the signal to my liking as well while a simple piece of software can do the same .... Am I right in my choice? *shrug*
I mostly agree with Whazzup's comments in this thread unless it concens the A8. I found it less than impressive but he loves it. Everyone's taste matters.
See my comment on TWerk's post. Neither me nor you both are wrong or right. Your solution alters the signal path which I don't like but gives the desired results. My solution gives the desired results, theoretically speaking without altering the signal path. But in practice it does since we get a different sound be at at a higher cost. I'm starting to confuse myself here.
So the last line in your comment absolutely makes sense and should be the first thing to explore, preferably with a free trial of software which wouldn't cost anything and gives you 30 days of experimenting.
The Lawton Fostex mods aren't similar to the Denon mods, they're actually about the same and are meant to do the same thing allbeit an improved version with different materials for the dampening. The D-7000 is different from the TH-900 however, the TH-900 simply is a perfected version of the D-7000.
Matt is right, the stage 1 mods alone don't do the trick without bigger cups, be they Lawton or not (I had much bigger cups with the LaLaNo 7000). Indeed, the fatter and angled pads should be a part of it as well. In my experience using only the pads made an improvemtnt, but using only one of the two other mods made it worse. The combo of the three gave the best results. Adding the cable makes it better, it gives you "more" of the same at a rather high cost but iot doesn't make it more right. IMO an expensive pair of phones like this is worth the price to get the best out of it but that's as matter everyone should decide for themselves. In any case I'd advise to either do the three mods (dampening, pads and cups) together or don't do them at all.
