A good PP amp holds together better than SET headphone amps, even if I say so myself.

SETs have about 20-25% usable power. A good PP amp has more like 95%. On phones, the SET will sound louder but when you measure the output power you find out it isn't. This is just due to the increased distortion of SETs; the ear uses higher ordered harmonics to sense sound pressure; you eliminate those as you can with a good PP amp and it doesn't sound as 'loud'.

You could also use a properly refurbished Dynaco ST35. They are also available as kit new these days. https://www.dynakitparts.com/shop/st-35-kit-120-vac/

Manley makes two amps suitable for headphone use

        Does XLR 4 pin provide better electrical contact than a 1/4" "locking" style plug ? - peppy m. 04:39:48 01/01/25 (4)
        
        Not really. The reason for 4-wires is better sound - Ralph 12:40:30 01/02/25 (3)
        
        I listen through 6 wires... - peppy m. 17:34:26 01/02/25 (2)
