PL EVO Pre - Output transformers!


I am not really in the market, but this caught my eye. According to Herb Rich at Stereophile:

this pre uses output transformers, possibly meaning there is no DC blocking capacitor like most tube pres have.

Very interesting! And worth a listen.

Best,

so do output transformers in a preamp add distortion or not
Colouration "mellow warm" is a form of distortion. Good caps get closer to the sound of direct coupling.

output transformers George, and they tend to be less colorful. Just mellow and warm.
To me they are bandwidth limited, can ring, have distortion (mellow and warm) and can compress compared to a good cap. DC coupling is way out in front of both.

Cheers George
I rather listen through a "good" cap than an output transformer, and the "best cap" is "no cap". DC coupling with well designed servo's sounds better again, than either cap or transformer.
