The Dx300 in it native is very tube like and without tubes!!! That is the craziest thing about the Dx300. The only DAP I have heard to exhibit this phenomenon without tubes.
I love my Dx312EX by a lot and lot, because this hybrid signatures between the liquidity, the connections, engagement of musical notes in the performances, but does not lack any details and fidelity. It is just purely amazing. I did a lot of tweaking and honestly, I never expected it to be this good….but it surprised me. If anyone has ever listened to a good 2A3 tubes systems, they know how amazingly engaging it is with vocal. It is like the singer is singing right in front of you, in the acoustic room, just you, the bands, and the singer. Yes, the Dx312 can achieve that with EX. It will melt your heart, if vocal and 2A3 signatures is what you love.
The W mod on Amp12 aimed toward elevating Ibasso house sound, so it has more micro dynamics, extensions, separations and staging overall. Both are amazing, period…or should I say, Ibasso is amazing and the Dx300 is amazing
