I thought about it enough to warrant sending Decware an email. The lead time is 8-12 weeks and I'm too impatient to wait that long.
Is there such thing as a single-ended 10 watt headphone amp? That's what I'm searching for.
don't know exact wattages , but how about the bryston bha-1, or the big hifiman(5 watts-50ohm) ? both have single ended as well as balanced headphone outputs
the EF-6 is single ended front to back.....the 4 pin XLR is a courtesy output and runs as single ended.....5 watts per channel
Audio gd SA-31SE is 10W @ 40 ohm
Audio gd Precision 1 is 16W @ 40 ohm
Do you mean single-ended as in output type of single-ended as in circuit design?
If the former, the AudioGD SA31SE, as i019791 pointed out (I own it and it is technically a very, very good amp - pretty much at the point where I dont feel the urge to spend any more on solid-state amplification, despite having a fairly flexible budget).
If the latter, 300B SETs typically provide about 8W output. I think that would be overkill - I used to get complaints from my neighbors listening to Stravinsky on a 3Wpc 2A3 amp, so i cannot imagine you'll need that much wattage for headphones. Also, tube amps clip a lot more gently/pleasantly than solid state amps, so the peak power requirements can be a lot lower (at 110dB, you arent listening to fine details anyway).
