I've been snooping around and I've heard a few things: Since they are only 25ohm; even the output on my Zune should sound alright with the Denon AH-D5000s. Of course, a good amp will sound better, but the Denons won't be totally castrated if they don't have an "excellent" amplifier. they are "easy" to drive. That said, since they are 25ohm, apparently some high-powered amplifiers do not pair well with them. Amps designed to work best with 600ohm headphones might not sound all that great with the Denons. Also, I'm told that solid state amps should be a MUCH better choice for these phones than tube amps. I don't know how much of that is actually true, but that's the sort of stuff I've read. Anyway, So once I get the Denons in the mail, what should I get for an amplifier? Schiit Asgard looks REALLY cool, but that is "back order" so if I want one I'd have to wait. Little Dot I+ is super affordable (almost too affordable; that worries me) and claims to do low impedance headphones very well, but that is tube and I hear Denons hate tubes. Fiio E7+E9 thing gets a lot of talk here, but I am somehow turned off by that idea and would rather have just a plain, discrete amplifier that just has RCA jacks on the back and a headphone jack on the front -- simple and traditional, you know? Does anyone have suggestions? I don't want to go too cheap, because then I will worry that my simple pioneer headphone out will probably be just as good, but I don't want to spend much more than $300, either, because I am merely a college student with a part time job. Any ideas?
