JMcMasterJ,
The limitation of polls is that while they can reflect popular consensus but not necessarily the sonic improvements that I am hoping for. Before starting these recent postings, I searched through past threads to gather the long list of amps. I also looked at some more active Headfi members who seemed experienced who also owned HD800s and listed their equipment in their profiles (including JMcMasterJ). Here is what I found:
AMB Audio Sigma/Beta 22 - ipodpj, momijigmo, uncle erik, preproman, shahrose, johnwmclean, baka1969 (7)
EC Super 7 - minimus, cee tee, anaxilus, jmcmasterj (4)
EC Zana Deux SE - uncle erik, dallan, bourneperfect, mr sneis (4)
Headamp GS-X - macedonianhero, preproman, asr (3)
Violectric V200 - dallan, rawrster, musicman59 (3
Woo Audio WA22 - minimus, grokit (2)
Cavalli Liquid Fire - macedonianhero, olias of sunhillow (2)
Grace Design m903 - john willett, olias of sunhillow (2)
EC Balancing Act - balderon, purrin (2)
HeadAmp GS-1 - momijigmo, mr sneis (2)
Bryston BHA-1 - maxvla, olias of sunhillow (2)
So based on a sample of experienced Headfi posters who all own HD800s, it appears as if the sigma/beta 22 is the most popular among my sample. It was also interesting to see how some of you transitioned through a series of amps over the last 3-4 years and others stayed with one amp.
This however, does not mean that this is the amp that I am seeking. My definition of "good" may differ from theirs. That is why I tried to detail the sonic attributes that I was looking to improve ( bass, details and imaging). The question may be better dealt with through discussion rather than a poll.
Respectfully,
Bob
