November 23, 200718 yr Yes I noticed that too. I think my Ed 9s do well for new age that's heavy on the synthesizer, at least compared to the $300 range with my new amp. Seems like the iMod isn't received as well here... especially that new guy with a big "home source = iMod w/ vcap" in his sig from HF.
November 23, 200718 yr Seems like the iMod isn't received as well here... especially that new guy with a big "home source = iMod w/ vcap" in his sig from HF. Hmm, yes, the iMod seems to be grouped together with ALO a lot.
November 23, 200718 yr Given that the two have an exclusive business partnership, it's going to be damn obviously they are lumped together. Moreover, it is a great example of head fi super hype. And to be on topic I discovered Head Case when tkam showed it to me
November 23, 200718 yr then again...There are always exceptions to the rule. I think it is more likely, in this case, that Jay is just in a bitchy mood.
November 23, 200718 yr I did not do this for fun. It was my job. And yes, pretty much what the guy above said. The signal was taken in the time domain. We used Matlab for signal analysis (FFT, transforms, etc). Most of the "better" amps were very linear and did not add any THD to the signal (or at least none that I could see). The other stuff we did was common mode rejection and sinad testing. We used a Tek TDS7k scope in a rack. We ran the scope over GPIB-Ethernet bridge on software I wrote in LabView to acquire and save the signal which would then be post-processed and analyzed in Matlab. Also, I'm not really sure why I even brought up the topic over at head-fi or here (and regret doing so). . . it's not in my personal interest to dissuade people from buying amps. . . so I'm going to stop here by qualifying what I've said. I'll just add that low THD figures don't necessarily mean better sound. A lot of times, the reason why an amplifier sounds better is because those non-linearities in the signal path add harmonics/color that translate to "improved" sound to the human ear. And sometimes, when we remove non-linear components from the signal path, the sound "improves" because we are taking away the coloration. . . and that being the case . . . we are really looking for amps that color the sound just right, not "great" amps that are so minimalistic and linear that signal in = signal out. A lot of what "sounds good" in combination with an amp also has to do with how the audio was originally mastered. Anyways, sorry for polluting the "how did you discover head-case" thread with this stuff. . . No wonder why there was no change; he didn't have wood blocks beneath his oscilloscope.
November 23, 200718 yr Oh well, I hope its better here. and in your next post... Also, I'm not really sure why I even brought up the topic over at head-fi or here (and regret doing so). . So you found it is worst here quickly by what you have said in your second post?
November 23, 200718 yr I was going to donate all my audio gears in a supreme final gift to the Head-Fi community, wrote a thread accordingly, pressed the last keyboard key and....Bang.....no more Head-fi.... Amicalement EDIT: to answer the initial question: pure and simple bad luck!!!
November 23, 200718 yr From a post of another member of the German hifi-forum. They were discussing head-fi downtime and international alternatives. That would have been me I found a reference to head-case in a thread about some amp (can't remember the model anymore) over at postjacks forum, two weeks or so before the crash. I doubt that it has been there for long....

November 23, 200718 yr I was bored one night and did a search for headphone forums on Google and this place popped up. I knew it was very different from HF with the very first post I read. It was someone who was asking what everyone thought of his Ray Samuels amp. Boy, did he ever ask the wrong question. I almost felt bad for the guy. I've been trying to thicken my skin ever since!

November 24, 200718 yr Matlab is the greatest thing ever. Well, next to baguettes. Matlab is the law. Baguettes are life.
November 24, 200718 yr What? You think this is some secret society you have here? Well it was originally invite only. Biggie.
November 24, 200718 yr Well it was originally invite only. Biggie. Maybe it is time to return to the womb.
November 24, 200718 yr Go Mathematica 6!!! now mathematica was a good program. i think i used it my freshman year in college. man i miss undergrad...
