PL EVO Pre - Output transformers!

I am not really in the market, but this caught my eye. According to Herb Rich at Stereophile:
https://www.stereophile.com/content/primaluna-evo-400-preamplifier
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,
E

Those transformers 4 for balanced input and two for balanced output,I think the single ended output still capacitor coupled.

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.

Thanks @imhififan !!
I like the sound of good output transformers, George, and they tend to be less colorful. Just mellow and warm.

For balanced/unbalanced conversion in TUBE pre, I prefer transformer than op-amp.
