I own the Primaluna Dialogue Premium HD.
The headphone output delivers a whopping 7 Watts on 60 Ohmm. Amplify Susvara, Utopia and HD800 very well. However, Primaluna HD has 8 power tubes and gives more control over the low range than models with 4 tubes.
With Primaluna I sold all the other headphone amps (V281, Taurus, Wa22 and other very good handcrafted ones.

My only complaint about EVO 100 is its small soundstage. Therefore I was wondering if the 300 will have a larger soundstage.

Have you tried using NOS preamp tubes?
On my P.L. I put two Amperex Buggle Boy (gain) and 4 Telefunken (drive).

Very interested in that amp. Do you still own it?

Yes, I still own it. I am very satisfied.
