High Notes

MQA Delight

If you want to test out the joys of MQA (Master Quality Audio) on Tidal, look no further than the Pre Box S2 Digital. It’s a great DAC and will do very hi-res audio.

Tiny Box. Huge Feature Set.

MQA, can be a preamp, great headphone amp, super hi-res audio capabilities, very low jitter, DSD capable. Yes, you get all this in a very well made, yet tiny $400 box. Simply amazing.
