I am thinking about getting a new amp. I am currently going to be using the Singlepower MPX3 Slam. The headphones I will be using are the Sony MDR 10s and the Grado PS1000. The amps I am thinking about getting are the Woo Audio WA5 LE, the Eddie Current Zana Duex, EAR HP4 (good with grados?), RSA Raptor or Apache and maybe a solid state amp if I could get one that performs at a high level, suggestions? Or, I may just stick with the MPX3 Slam if none of the above are a step up. So, any suggestions on which direction I may want to look would be appreciated. Thanks
