7th Acoustics, a boutique Indonesian brand led by Stephen Syn, offers the Supernova as their standout 6BA in-ear monitor (IEM). This flagship model is renowned for its effortless tonality and coherence, featuring a durable design with a lacquered abalone faceplate and a smooth resin shell. While its unique tuning delivers a natural midrange, some users might find the upper treble a bit subdued.
