ive been lurking these forums for quiet a while. I recently purchased a pair of hd650's (upgraded from 558's) which i use for gaming and music.
I have been looking into getting a amp for them and the most recommended around here seems to be the bottlehead crack with the speedball upgrade(I would love to try a valve amp). Now atm i have a essence stx, which is also connected to my audioengine A5+. This means to make use of the bottlehead i would be constantly swapping the rca's when i want to use the speakers or vice versa.
I dont mind spending a bit extra on an amp like a shiit lyr or woo audio wa3, which have rca out. But as an electrician would like to build my own amp.
The second question which is sort of related is about the grado sr325's. As i listen to alot of different genre's i have found the sennheisers a bit flat sounding for rock and the like. Dont get me wrong i love the 650's and would not give them up, but i was looking at buying a second pair of headphones which are a bit more suited for the different styles of music and were a bit for exciting to listen too.
The related part about the questions is having an amp the could possibly suit both sets?
hope this made sense.
