Hey guys, first post here, hoping someone can kindly help me out. My love for good sound started when i purchased a decent Hi-Fi (Rega Brio-R, Rega DAC and Monitor Audio RX6 Speakers). Since then i have ventured off in to Headphones so i can listen of a night without annoying everyone in the house. I brought myself a pair of Grado SR80i's and have absolutely fallen in love with them. The main points i love about these cans are the mid range (its just so abundant ), the detail they dig up and how accurate they are, i was extremely surprised when i got them at how talented the SR80i's are for their price. What I'm looking for in an upgrade is those points but a more airy sound stage, a little more bass weight, trebles that aren't quite as harsh and obviously something that's better all round. Currently I'm using the Rega DAC from my Hi-Fi, my PC and a little tube amp i brought off ebay from a guy in Western Australia, his business name is "Freds Amps" its the 12AU7 model modified to have RCA inputs for the Rega DAC. Some might say crazy but at this point I'm thinking the GS1000i's, I know what I'm like (I'm very prone to upgradeits lol). Obviously if i did go for the GS1000i's i would get a better amp and another DAC so i can keep the Rega with my Hi-Fi. What do you guys think? Would i be blown away compared to my SR80i's? Would they live up to what I'm looking for as mentioned above? Many thanks in advance guys, I'm looking forward to reading some opinions.
