At nearly 10, 000 posts and having been here for 2.5 years or so...you must have figured out the average head-fi mentality by now?
Step 1) post a question about which amp is the best (don't bother doing some research and using the search)
Step 2) get a bunch of newbies and/or fanboys and/or both chiming in that amp X is the BESTEST thing ever and if you can't get X then get Y or Z from the same company. If you are lucky a flame war will erupt in said thread from the 2-3 competing camps of fanboys.
Step 3) buy an amp
Step 4) join the heard and start posting how awesome it is along with the rest of the sheep
Step 5) dump the amp when the next cycle of releases are out (every 6 months or so)
Step 6) immediately claim that the newer amps trounce all older amps.
Step 7) repeat ad infinitum
What perpetually strikes me as odd is when I read "meet impression" threads and I read things like:
Cary + R10 was the best system
Maxed out Melos + HP-1 was the best system
Ear HP4 + RS-1 was the best system
Single Power Maxed out Maestro + R10's was the best system
HE90 + HEV90 (Big O!) was the best system
HD6x0 + Blockhead/Max v2 was the best system.
Sure one will get some fantastic words about nearly anything out there but overall this is the stuff that gets mentioned time and time again.
Now, Cary, Melos, Ear and HEV90 are pretty old amps around these parts and I am floored at how they are able of not only retaining their oscillating spots at number one but perpetually remain in the top 10, if not the top 5. The killer is the Melos in all of this...it can be had for 200-400 on the forums often (if not yet modded) and then for an extra 400-600 can be taken to astronomical levels, yet I see people dropping 2k+ on amps that don't better it, sound different sure, but don't better it. I don't have as much experience with the PPA as others but it is an outstanding amp and when maxed out is easily one of the best solid state amps ever designed, but it just doesn't garner the fanfare it used to because like goldfish, the memories of the average head-fier are very very short.
But here is a secret....for the most part (particulary in the area of amp circuits) audio sales THRIVE on this mentality and require hyperbole galore to entice people to drop their old gear and buy the newest fantangled thing because it is shiner, bigger (maybe) and has even more adjectives describing it, like TOTAL REFERENCE! or ABSOLUTE TOTAL REFERENCE! Redundant when something is already the reference right? Heh...well, not when it can be the TOTAL ABSOLUTE BEST EVER CREATED BY SOME ALMIGHTY DIETY REFERENCE!
A great way to build an AWESOME audio system is to read OLD threads and find out what was amazing back then then track through the years following the posting history of those that had those amps and those that heard them and find out what is still hot and what is not and why. When an HD600 + Headroom Max v1 is still one of the best systems ever (yet hardly gets recommended) it demonstrates the logic behind far too many around here, however, if a max comes up for sale...and with the ridiculously low prices of used HD600's...one can sneak away with one of the best of all time for far cheaper than most of the newer stuff getting released which is but a fad.
