私個人の主観ですが、とても良い商品です。sundara closed backを4.4mmバランス接続で聞きました。low gain nosが良かったです。ポータブル機なので比較すべきではありませんが、これまでifi-audio idsd diabloのturboで聞いてきました。asioやwasapiは勿論、そうでない音源をequalizer apo+peaceでsundara closed back向けに調整しても、ef400は優れていると思います。相性もですが、ヘッドフォンの評価は上流まで含めた判断が必要だと改めて感じました。
Ottimo ampli, potente e dettagliato! Ottima anche Hifiman per la celerità della spedizione! Bravi!
Perfect
I have no issues with the sound, but I have to try it with some other headphones (mine is Audeze LCD II Clasic). I have compliant about potentiometer. It has a little empty movement when turning up an down. Maybe this was the reason it was returned in first place.
best regards
