I'm a beginner, just started head-fi.
DAC is iFi zen dac V2/Headphones have HIFIMAN's SUNDARA.
The source device is a normal home computer (window 11).
I use Tidal&Spotify and enjoy classical music, crossover music, and contemporary jazz performances and K-Pop.
I'm currently using it directly to the zen dac V2, but I'm going to buy a headphone amplifier for better sound quality.
I look forward to your advice on which of the two products, zen can signature HFM and DROP THX aaa 789, will suit my current situation.
(The budget does not exceed U$300)
