Wasn't sure which forum would be best for this, picked Effects since they serve not only as headphone amps but preamps as well. My fifth or so Vox amPlug broke, as they do, and I'm just not going to replace it with another. Even if I could find it, some places are sold out of it. Taking it as a sign to finally get something different this time. Between these two the Ashdown seemed at first to be the clear winner, having such a nice size, form factor and simplicity, plus the digital output is a nice feature. The built-in rechargeable battery is both a good idea, and is replaceable, but seems proprietary which may make it hard to find in the future; also it has a weird 10v charger. The Palmer however has nice other features with sims, Gain control, Fuzz, O/d, and more tonal control. It has a simple 9v battery bay for backup. They're both about the same $200 price although the Palmer doesn't come with a charger. While my primary need is for a headphone amp, the additional tonality makes these both worth of serious consideration but am still on the fence about which I will go with. Any actual experiences with these would be welcome. Or, is there a Dark Horse headphone amp with Aux In that I am not considering (besides the Phil Jones, which looks good at about double the price which is out of my range for now).
