DIY version up DIY 846 12BA Blue ver. ▲ The photos are of the actual product. ● Unlike scalpers, we offer a thorough guarantee. We can handle repairs, exchanges, fine-tuning, and custom configurations! The internal components are original KNOWLES units, not Chinese-made BAs. Detailed Configuration: High Frequency: TWFK-30017 x 2 Mid Frequency: ED-29689 x 2 Low Frequency: CI-22955 x 2 While the SE846 has 4 drivers, this model has 6 BA drivers, allowing for a clean sound across the entire frequency range, addressing the previous issue with the low frequencies. The high frequencies are handled by the well-regarded TWFK, delivering a clear and brilliant sound quality. You'll hear sounds you couldn't hear before, with a greater amount of audio information and a wider soundstage... The extended high frequencies, brilliance, and tight low frequencies are all highly praised. The price is also lower because there is no brand premium from the manufacturer. Aging for approximately 50-100 hours is recommended. It can be sufficiently driven by regular Hi-Res smartphones, DAPs, and computers. Even more performance can be achieved by using a portable amplifier. This product is not an SE846. In my subjective opinion, I highly recommend this over the SE846 in terms of cost performance.
