A few weeks ago, I was going back and forth between the He-6 and SR-507. I couldn't afford both and since I already had a pair of lambda signatures, I chose the HE-6. Well since that time I've sold the sigs and now have a pair of SR-407. So I can't compare them directly to the sigs but from memory I must say that they are a nice upgrade. Out of the box, they sound similar. They both are very detailed, extremely transparant, and have a very nice soundstage. Another thing I loved about the sigs was just how cohesive the sound was. There weren't any noticeable dips or peaks in the frequecy range. Everything was just so coherent. The same is also true about the 407s, but one thing the sigs have that the 407s doesn't have is that infamous upper midrange etch. The sigs would have been almost perfect if it wasn't for that. So I'm glad to report the the etch is gone. As a result the sound smoother and grain free. As clear sounding as the sigs were, the 407s are even more clear tha the sigs. Another improvement is the bass. There's not as much quantity, but the quality is better. The bass isn't boomy(a trait of all lambas). It isn't quiet as tight as the bass on my HE-6s, but it's close. The bass is also more refined. In short I would say that the 407 are a more refined, smoother sounding version of the sigs without the etch. This is a wonderful feat because I prefer the sigs over any dynamic can I've ever listened to. And the best part is, these are out of the box impressions. So they aren't even burned in yet. I will report back once I have some more time on these.
