I'm planning to replace my hi-fi with a headphone rig. I've underlined what I was thinking to buy, in addition to the headphones
OVERALL BUDGET: 600€ (I consider the secondhand market)
USE: Both outdoor (on trains, at the university), both at home
SOURCE: iPhone 4 (192kbps) + low-quality friendly portable amp / macbook pro + hiface + Valab NOS dac (will replace these two if needed) + full-size amp at home
SIGNATURE: Deep but clear bass, possibly realistic trebles, good stage (at least with home configuration). Strong sound temper, but also sturdy manufacuring.
I have been adviced for the Sony MDR-7520 which don't need amplification. But I'd prefer to have different amplifications for mobility and home due to the different quality of the source. What do you think? Is this a correct approach?
Thank You in advance!
There's generally nothing wrong with throwing an amp in between an highly efficient can and its source. Most of the time, it will help. I, too, was looking at the MDR-7520, but I just happen to find a real great deal on a Shure SRH940 instead. When I get around to it, I'll seek out the 7520 just to hear it.
Maybe throw the Shure SRH840 and DT770 Pro just to have something else to compare the 7520 to.
