"nsk",
tutaj krótki opis, porównanie właśnie 60 do 225 przez Shauna Gostelowa z portalu hifiheadphones. 60 to tylko najniższy model, da się o wiele lepiej, a od 225 też da się wiele lepiej i kładę łeb na pniok za to ;)
"Grado SR225 - best headphones available at this price?
Somewhere near the middle of the Grado headphone range is the rather nice sounding Grado SR225. Compared with the budget priced Grado SR60, the SR225 is a much more refined sounding headphone.
The Grado SR225 is a low impedance headphones, so it is quite possible to drive it with a low spec headphone output, as found on portable players like the iPod and laptops.
Without a dedicated headphone amplifier the SR225 will give a stunning performance, with solid bass extension and high end intensity that will make you sit up and pay attention. On the other hand, with a good quality headphone amplifier the Grado SR225 will open up and you will experience a new level of sonic detail and even tighter bass response."
