I am again very happy with the Little Dot Mk6 great synergy with the K1000 when tubed correctly. But was curious to obtain a WA22 for the LO/HI impedance capability and so many output selections.
It just seem like a amp that can drive so many different phones and being transformer output there would be no voltage swing on low impedance phones.
Little Dot MK6 being a OTL/OCL design allows high impedance phones to shine. Oh well there is always some trade off involved.
