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 units, 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 deficiencies, even in the low frequencies, which were a challenge. The high frequencies are handled by the well-regarded TWFK, providing a clear and brilliant sound quality with excellent extension. You'll hear sounds you couldn't hear before, with a lot of sound information, and a wide soundstage... The high-frequency extension, brilliance, and 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 even with 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.
