Hello!
Right, let's address the big one that came earlier in the thread. Why are we doing 150 ohm IEMs?
To those who said we're just using them to help sell Dacamp units, I think you're possibly looking at things the wrong way. These products are part of a new collection were developed side-by-side, designed to work together from day one. Anyone who's tried an existing RHA product will likely say that they don't need an amp, so if we'd launched an amp without a headphone that really benefits from it, it would be a bit odd. Similarly, if we'd launched the headphones that need amping without an amp to drive them, it would be a bit odd. That said, the two IEMs will happily run from a good range of amps made by other companies.
The IEMs specifically have the impedance they do because of performance. Our engineers were working on wideband dynamic drivers and found that a config with higher impedance allows them to get better control over the higher frequencies in the extended response. At the same time. they were working on the ceramic driver, and the two techs compliment each other very nicely - piezo drivers have very high impedance, a standard dynamic alongside one wouldn't work very well. The full wideband version of the CL Dynamic went into the CL750, and a slightly adjusted version went into the CL1 Ceramic to work with the ceramic plate driver.
Some quickfire responses to some of the other questions:
Mini XLR - We tried a lot of different balanced options for the product and settled on Mini XLR because it's small, keeps all the poles separated and is durable. We know,
there are lots of standards within balanced, and we're not trying to make the situation any more complicated, but we really felt that Mini XLR has lots of positives and few drawbacks. We'll be offering a range of cables and adapters of our own, and working with cable makers to ensure that there are third party options for anyone looking for an alternative.
sMMCX - It's a version of MMCX our engineers developed to be slightly slimmer and also more secure, so in a sense, it is proprietary. Much like the above, we weren't super happy with standard offerings in terms of capabilities and durability, and we will be making the spec available to third parties.
Input/output covers - This is something I've spoken to our guys about today and we're going to start looking into it to see if there's something we can do to go with the planned L1 case.
Naming - Dacamp is actually a trademark of RHA, which is cool, and L1 is the model number, that's all I'll say for now on those. I'm hoping someone will figure out where we (partially) got the CL Series name from...
Battery life - Up to ten hours is via the 3.5mm, but in testing, gain settings and balanced out aren't hugely influential on battery life.
Keep'em coming, and we'll try our best to get replies up regularly.
