with all due respect this is wrong approach in my book. it is not necessary to listen to all crap in order to be able to appreciate good and expensive gear... if i know how live music and good concert halls sound then owning cheap and crap will only be pain on my ears. this was exactly the reason why i listened to portable gear very rare or when on business trip in a hotel or on plane only. because i know how music should sound... but then i bumped into headfi and vola i began discover music revelation thanks to great products. 1p2 for me became like gear search story climax and ear opener. i wish i bought that right away... but no, i was stupid
now, why would i be happy to own tons of cheap gear before purchasing expensive gear IF not only due to the size of my wallet?
i can tell i could be much better off IF purchased 1p2 straight away and i did not need cheap gear to appreciate my 1p2. mistakenly i started to believe in law of diminishing returns and that cost me purchasing about four different IEMs before i came to listen to 1p2. if i would value this exercise in money terms then i am afraid i paid much more than our newbie with 1p2 and ak120. so the law of diminishing returns in fact means only the limits of the wallet, that's it... otherwise collecting tons of cheap gear before purchasing expensive is waste of money.
sorry mate for disagreeing but i am not in the music or gear industry and i purchase things for enjoyment and listening to the music the way i want.
going for the right gear saves you money and headache... the only downside would be if you struck the best of best right away there is less chance you will be coming back to HeadFi discussing all this gear
