Hi. I'm searching for an usb dac with punchy bass. I'll give you some background info about what I like to give you a clearer picture of what I'm searching for. I like: -Strong punchy bass -Small amount of subbass -Clear vocals -Soundstage I don't like: -Sharp highs/sibilance -Hearing the constant bass bwooooooom throughout the song (it makes the listening tiresome). What I'd like to have: -Android compatibility -Bass controls: a) I'd also like to be able to control the bass on my android. b) If the DAC has a real kick out of the box there's no need for bass controls -Portability My headphones are: Encore Rockmasters OE The sound that I enjoyed the most was on my modded Samsung J5 with Viper4Android with settings: - +15.4 dB Bass Boost - Pure bass+ - 71 Hz crossover freq Sadly I switched phones and I don't want to lose my warranty by modding, so viper is a no no for me for about 2 years. (please don't tell me to switch headphones, I've heard the sound that I liked on them and now I just want a dac that sounds similar) I'm using the soundblaster E5, but I hate the bass on it. It's strong but the "bwooooom" is always present, even in the songs I've never heard it in. My budget is 150$. I really really appreciate any help. I'll be really happy if I can find something I like thanks to you, because for now I'm losing my drive to listen to music because it doesn't sound good.Thanks.
