My friend..we are going to much into 'an amp is only good when u can measure it' as u know..as i hope ur am audiophile as well...is not true...check the tube amps for example..the worst measurable amps with designs that basically goes back to the beginning of the fomer century...and we al know..yep..u too (At least i hope u did!) how special some can sound...and i mean addictive special..not just nice sounding...and many GOOD measuring SS amps wont even touch some tubeamps soundwise and how it plays music...
So Stan..i know ur a numbers man..and i know u swear on that while buying ur audio...hope u one day will find out that numbers are not the most important factor in choosin ur audio equipment...i have some friends who are in the music industry for at least 30 years now....a pianist and a guitarist (and a non professional weirdo who plays very beautiful violin in his spare time) and NO ONE bought their stuff by how their measure..BUT how they sound! Not one single one...and they say even their techicians are like that..only the recording/mix tables etc..so the technical stuff they need to RECORD etc. Has to be technically perfect (i understand some stuff gets calibrated every other time!).. But the instruments? Ears!!!!
One of them talked me into his audio hobby in home...as before that i was all about car audio (attended few contest also) and thats a whole different ballgame with programs calculating (using mics on different spots in the car) the time music travels from one side to others and what filters to use so the interior influence of the car will be neutralized....thats very technical...for that i can understand numbers are important...but still..the speakers in their custommade enclosures and in their spots (spots also calculated and placed in a certain angle..etc.) are chosen for their soundsignature at the end....
But headphone rigs are very simple...u buy the headphone that u like sounding, buy the amp that makes it sing and get the dac that complements it..on top of that u can try out cables to squize the last bit of musicality out of ur rig...and then ur done...for this u dont need NO analyzer..for what? To measure what angle u have to put ur amp towards u? The way u have to put the headband on ur head? (which could actually change the soundstage by the way if u listen very carefully!)..
I think u, stan, are one of those who swear on the O2 principle...Am sure if he had 5w more u probably would had one by now...as thats..according to ur believes...the perfect amp to play music on...oops..wrongly said...the perfect amp to let the current through to your headphones..totally colorless...and totally boring..but hey..thats a personal preference...and many..and i mean many go by that...as that amp sold by the thousands if i am not mistaken... Good for them
Ok..lets end this by saying we agree in not agreeing...its a real shame ur so far away..as i know where ur coming from my friend..and am not attacking u..i once told u many of my friends are very practical thinking technical Engineers..in several areas..and although most of them said (even the ones who earn a huge salery) that i am a bit nuts spending this amount of money on a headphone rig, they all agree it sounds very special..and ALL said they didnt expected that! As for them headphone rigs are just second grade audio, two of them ordered a hd800 and their sennheiser TOTL amp to go with it (they find hifiman a bit to risky..their words!!) recently... So i won two for the headphone team
but if u ever visit amsterdam...give me a call...am not saying i will transform u in a babbling emotional audiophile..u will still be ur technical practical urself..but am sure u will believe that amps can sound better then others
