Superbestaudiofriends.org (SBAF) is a private club comprising like-minded audio enthusiasts (mostly in the personal audio space, with a few branching out to two-channel) who splintered off mostly from Head-Fi.org. New memberships are currently restricted to open registration periods or by invitation. We do this to keep the noise level down, quality of content high, and to promote a strong community aspect where everybody knows everybody else to some extent. All content however is open for the public to digest. The downside to closed like-minded community is that we will be less open to a large variety of opinions were all audio gear is rated four point five or five stars (out of five). SBAF is not 1000 reviews by 500 random people (250 of them probably shills or socketpuppets), all of which are given garish 1200 x 800 pixel home page treatment. This approach is self-serving to someone who just wants to enrich himself with money from sponsors. SBAF is not about that. SBAF is about promoting good sound. SBAF is willing to draw a line in the sand of what constitutes good gear and good sound. That being said, SBAF opinions of gear are not monolithic. Senior members actually have different tastes. For example, the most respected reviewers and members actually use different sources (no, not everyone uses Yggy, and some such as myself are vinylheads). Our style of reviews and impressions is usually comparative, comparing one piece of gear with other similar gears. Our observations are nuanced and qualified, discussing various aspects of sound reproduction (as opposed to a simplistic "better" or "worse"). Readers should make an attempt to understand the personal preferences and associated gear of the reviewers and the vocabulary used here. This takes time and effort. "Lurk moar" as as we say. There is no way around this. One crucial aspect of SBAF is measurements. We like measurements, but we are not measurement extremists. We understand that most measurements of DACs (99% of DACs measure extremely well) won't tell us much. Unlike John Atkinson or nwavguy, we don't freak about about spurae 128db down from the fundamental signal. But we also understand that measurements of headphones and transducers, where errors are gross, will tell us quite a bit - especially if we look past just frequency response to consider CSDs and harmonic distortion. What we are primarily interested in is how measurements correlate to observed sound phenomenon. Measurements often serve as a useful tool for members to request to be added (or not added) to a gear loaner. Measurements can serve as a good screening tool and augment subjective impressions. Finally SBAF purchases its own gear for its gear loaner program, which is only available to senior members. Gear in the loaner program is often measured by several members, all using slightly differently methodologies, and passed around to senior members who will offer their subjective opinions. As far as rules of conduct for new members, there are no (no longer as of December 25, 2017) written rules of conduct other than When in Rome, do as Romans do, and to also introduce yourself in this read: http://www.superbestaudiofriends.org/index.php?threads/new-members-introduce-yourself.17/ Think of SBAF as your local neighbor dive bar where conversations are between people who know each other. If you have a strong opinion, don't immediately barge in without expecting a regular patron to swing a barstool over your head. Get a lay of the land. Understand the local customs. Get to know the people. You don't want to be the guy walking into a Barca pub arguing Ronaldo is way better than Messi.
