Does anyone know any audio equipment stores in dallas?

I’m somewhat trying to get into Hi-Fi audio and want to buy a DAC, but i don’t know where to start. I bought some Sennheiser’s 660s, and i’ve done a bit of research and seen i need a DAC to get lossless audio on apple music with 24 bit/192 kHz. So if anyone has any suggestions for audio stores where i can maybe test out a DAC, it would be much appreciated!! 🤠
