Now it seems to me that there is another spot on AC that someone talked about using speaker terminals to drive headphones. Maybe it was another site and my old, too full mind is mistaken again?!! And there I go having conversations with myself again. Lol.
I read your post above, but that slight turn-on pop that you get with the Sig 15 has nothing to do with it being a "voltage driven" or "current driven" amp. Nothing to do with TomS' question above. The pop is just the result of DC offset on the speaker posts at turn-on.
Which type of amp is the LIO? Would either be better to adapt to headphone use out of the speaker terminals than the other?
To be perfectly honest, I'm not sure I understand Tyll's terminology there.
LIO uses a Class AB MOSFET output stage with low output impedance. It is perfectly fine driving speakers that are 4, 8, 16-ohm - or even headphones in the 4 - 1000 ohm range. Impedance does not matter. Sensitivity of the headphone does matter. If it is a very sensitive headphone (e.g. like an in-ear monitor, IEM), I don't recommend using it with LIO, as there is too much gain and power.
For headphones that like a good dose of power (actually, what they really want is more voltage gain because they are not as sensitive) such as:
- Audeze LCD-2, LCD-3
- HiFiMan HE-1000, HE-6, HE-560, HE-500
- Sennheiser HD-600, 650, 800
- AKG K701, 702
- AKG K1000
The LIO MOSFET AMP could do a great job with them!
LIO does not have any turn on/off pop. There is a 10-second delay that we implement while the LIO MOSFET Amp
powers up and stabilizes.
All the best,
