I am a long-time lurker, first time subscriber/poster. I am looking for a decent entry-level amp for my Sennheiser HD650's (like everyone else). Looking through recent threads, people seem to have a lot of good things to say about the NFB-12's, especially for its price-point. I have also been looking at the Schiit Valhalla and the NuForce Icon HDP.
Without knowing much about amplifier hardware I am having a hard time making a decision. I am leaning toward the Valhalla because of the 15 day trial and I dig their confidence, but I don't know much more than what I have been reading in these posts, which appear to be a bit subjective.
1. Schiit Valhalla (~$375)
2. NFB-12 (~$250)
3. NuForce Icon HDP (~$450)
Additional suggestions are welcome and thanks in advance for any advice!
