So much for a cheap amp upgrade...
As the topic says, I'm now trying to decide between the Singlepower PPX3 SLAM and the Mapletree Ear+Purist HD. I would have to find the Singlepower amp second hand to be able to afford it, probably in Canada (a long shot but I can wait). The Ear+HD is not worth buying used since I can get it tax-free here, and I seriously doubt I would be able to buy it second hand from a Canadian. They would likely end up being about the same price.
As I said in the previous thread, I currently own RS-1s and UM2s, and I will probably be picking up some Senns or Beyers in the not-too-distant future to see how I like them. However, RS-1s are my primary listening headphones, and I don't see that changing any time soon. The Ear+HD comes up in pretty much every discussion about RS-1 amps, and it definitely has a cult following. The same can be said for the Singlepower amp, though. I had a chat with tkam on IRC and came to the conclusion that the Singlepower amp would probably be the better of the two if I could find one, and I'm wondering what other people think. I was checking out some old head-fi threads on Singlepower amps, and it seems there was quite a contraversy over their design and internal construction a couple of years ago. Someone posted photos of supposed "sloppy wiring" and such and claimed that they don't work well with low impedance headphones, though PFK tells me the thread is full of RSA fanboys
Any thoughts? Also, what if I were offered a non-SLAM PPX3? Thanks again, guys.
