Need a little help understanding synergies between tube amps and headphones. I'm looking to upgrade, and in so doing, am trying to narrow down where/what I should be considering in terms of options. Hopefully knowing what works and doesn't, and why, will help.
What I do know I want a tube amp for the qualities they are generally known to provide, and am looking in the Valhalla, Bottle Crack, Little Dot MKIV range... Of course, I am (will be) then looking at headphones these obviously will drive well and fit my preferences. A few opening questions:
If I really want to get a pronounced effect from a headphone amp, is going higher in ohms necessary? Does dropping the ohms on a headphone so they work better with more portable player degrade quality in some respect?
I read many comments on how tube amps don't work well with low impedance phones - is this an opinion, or something scientific? Or, does it depend on specific characteristics of the amp, e.g. certain levels of output at various ohm factors?
Sorry - sort of mixed questions here, but I think the underlying confusion is clear. Of course, more specific questions on gear to follow....
Thanks in advance
