While I totally understand what Dan is saying, there are just some people who prefer the bloom, and less accurate bass. Yes, people do like coloration over accuracy at times.
The person in question, from all he has said, sounds like he'd prefer the colored bass over accurate bass.
Hell, I understand him. I prefer the colored Denon D7000 bass over everything else I've ever owned or tried. So, while he may be optimistic (and perhaps expectation bias might help him), I don't see him completely wanting the AD bass if he's been raising the VOLUME to get the bass he wants out of the MD. Raising the volume has emphasized that same bloom the AD has 'fixed'. We can argue, but fact is, he's been raising the volume for more bass.
So I'm just being logical here in saying the AD is probably not his best choice. He might like it, but I expect some buyer's remorse.
I want a pair of headphones that are closer to audiophile quality. I already have my fun, boomy-bassy cans.
I am quite capable of enjoying the Mad Dogs exactly as they are, without increasing the volume. It's just that on some songs, to get a similar toe-tapping enjoyment when compared to my bloomier cans, I need a bit more volume. I don't actually increase the volume anymore, but now I realize what was different about some songs when using the Mad Dogs.
Alternately, there are many songs that just blow me away on the Mad Dogs when compared to my other headphones. There is no perfect solution out there for me. Steve Miller's
Rock'n Me sounds much better with my bassy headphones, while Van Morrison's
Into the Mystic can nearly bring me to tears with the Mad Dogs.
I'm not one that really understands and can actually distinguish between the details between sound characteristics. From what Dan stated earlier about the bass, it makes perfect sense and I'm sure the bass is better in every way. But to an amateur like myself, it will most likely translate to my ears as not as much bass. I could be wrong, and I hope that I am, but either way I want to upgrade to the Alphas so that I can own a pair of headphones that an overwhelming majority of listeners seem to love for its ability to deliver audiophile quality sound.
There is little risk that I will not fall in love with the Alphas, as I already enjoy my Mad Dogs immensely.
For me, I honestly do not really know what ideal audiophile quality sounds like. When I hear a bass guitar play, it is in a bedroom, garage, bar, or a stadium built to seat fans at a basketball game. I've never been in anything remotely close to a quality listening environment or sound studio. The distortion and inferior qualities that might be present are probably closer to what I hear most of the time, so I am used to it. I'd love to have some special, treated room filled with Ethan Winer's bass traps all over the walls and ceilings for dedicated music listening, but I've never had the opportunity. I'm sure it would freak me out if I walked into one of these rooms.
