I just got my hands on a Timeless AE and listened to it all day yesterday, through RU6 line out to XD05 Bal, and was surprised to find myself liking it quite a lot, given that I usually enjoy warmer/thicker, full-sounding single dynamic driver IEMs. The Timeless AE seems to offer a lot of detail...

iirc, the theoretical guideline was that the driver impedance (IEM impedance) should be at least eight times the output impedance, and 56 ohms is high enough that impedance matching won't be an issue on virtually all devices I should think. Re-termination is above my pay grade, but I suppose it...

Such circuits also mean the balanced output draws more power than single-ended (which can be a drawback sometimes). And often output impedance is doubled. Not an issue for most IEMs, but it seems to cause impedance matching issues on low impedance IEMs, e.g. on my 9-ohm Audiosense T800 I prefer...
