DIY Version Up DIY 846 12BA ver + For SHURE Upgrade Cable Silver This is a set. ▲The photos are of the actual product. ●Unlike resellers, we offer a thorough warranty. We can handle repairs, replacements, fine-tuning, and custom configurations! The contents are not Chinese-made BA, but original KNOWLES units. 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 has 6 BA drivers, so it provides a clean sound across the entire range, without any excess or deficiency, even in the low frequencies, which were a challenge. The high frequencies are handled by the well-regarded TWFK, providing a clear and extended sound quality. You'll hear sounds you couldn't hear before, with a lot of sound information, and a wide soundstage... The extended high frequencies, the brilliance, and the tight bass are all highly praised. The price is also lower because there is no brand premium from the manufacturer. Aging for about 50-100 hours is recommended. It can be sufficiently driven by a regular Hi-Res smartphone, DAP, or computer. More performance can be achieved by using a portable amplifier, etc. This product is not an SE846. In my subjective opinion, I definitely recommend this over the SE846 in terms of cost performance.
