Interesting. Are you guys getting decent enough range with the knob? Isn't there a risk of blowing the drivers easily? I can only imagine this HE-6 or similarly hard to drive cans. In which scenarios are the resistor network used?
Hey man! Seems like I'm bumping into you all over Head-Fi
The usable range of volume control is an issue with a lot of amps and setups, which is one of the reasons some people are using resistor networks to regain (no pun intended-- ha!) some of that range. Yes, there is a risk of blowing the drivers, but it can be largely mitigated by a judicious use of the volume knob-- no big upswings in volume, and always start at zero and work your way up. (The possibilities for problems here can be reduced with a resistor network also). The HE-6 and K1000, being terrible inefficient, are the two that I've most often heard of people requiring speaker amps, although the HD800 is another headphone that gets brought up frequently as seeing improvement this way. People tend to try it with orthos pretty frequently, but the benefits with the Audezes seem less clear-cut than with the HE-6, at least from what I've read.
In addition to this thread, which is great, you might want to check out the "Amplification for HE-6" thread, where they go through a lot of other options as well. (I'd recommend the HE-6 thread itself, as there is a TON of info there, but it's approaching a thousand pages at this point, and only true nutters like me would read the entire thing, I think). Personally, I use a First Watt F5 clone directly into my HE-6 with no problems; I simply listen at very low ranges on my preamp (Audio-gd Master 8).
In general, using speaker amps requires a bit more care and common sense than using a headphone amp otherwise would, but the consensus seems to be you have the potential to get considerably better sound quality for your money this way. All the usual caveats apply, YMMV, etc.
