Under $300, is there another desktop headphone amp with more power and overall versatility than the NFB 15.1?
I don't own the NFB15.1, but I'm looking at buying one. Ideally, I'd like a DAC/Amp combo under $300 that will have plenty of power to drive any dynamic headphone I throw at it, and any reasonably drivable orthodynamic headphone as well (LCD-2 / HE-500 / etc). I'd also like a fairly neutral amp, which is why I thought I'd look into NFB 15.1 as opposed to NFB 12.1.
Right now I own the NuForce Icon HD. I use it with Grados, and admittedly it's pretty overkill for them as I can barely hear a difference between Grados through the Icon HD than straight out of an iPod. But I know Grados' design is such that they are easy to drive. From what I've read, however, the Icon HD doesn't have enough power for the heavy dogs.
I'm wanting to get into some of the top end headphones. Those "heavy dogs". Something along the lines of HE-500, LCD-2, HD-600/650, etc. All of which, I've heard, need power to sing. On paper, the NFB 15.1 has power!
Is there anything else below $300 that can match the power and neutrality of the NFB 15.1? Can anyone who owns it comment on it?
