We stumbled across RHA’s booth where we got to listen to both the MA750 (£79.95) and the T20 (£179.95). The T20 uses their Dual Coil dynamic driver technology which basically involves putting a second coil inside a central void in the main coil. Both of these are connected to the same diaphragm with the lower end of the frequencies being sent to the middle coil and higher frequencies to the outer coil. The opposite of every other concentric example I know of; very interesting. There is an additional apex which allows the voice coils are able to manipulate the different areas of the diaphragm to generate sound. We also have three filters, neutral, treble and bass depending on your personal preference. They look gorgeous; I absolutely love what RHA are doing with their injection moulded designs.  The 750 is a stainless steel construction that is again a very nice looking product with a single handmade driver and a very nice, high quality feel which is consistent with RHA products.

The RHA T20 uses the same housing as the T10 before it.

The 750, originally RHA’s flagship, now the third model in the range.

Both of these products are tilted to the “commercial” sound signature but in a way that I have to admit is really enjoyable and I can see audiophiles fully appreciating the technical ability of both of these earphones. Both of them offer a pretty flat, slightly warm signature with the T20 (neutral filters) being a more refined, clear step forward on a technical level. The T20 also seemed a little more obvious in the upper mids to treble. Somehow though the smooth, engaging effortlessness of the 750 is really nice and I think makes it a very attractive earphone in the price range. I hope to get a closer look at both products in the near future for a full review but until then, I am left with a very positive impression of what RHA are up to.

Me Wearing Them!

As well has showing of the T20 for the first time ever, RHA also had a brand new product on show. Currently named the DACAMP M1 (although I hope it ends up with some a little more creative) it is exactly what you imagine, a portable DAC/amp unit. Still being in development, it wasn’t listenable or finished in feature set. Some stuff we do know though is that it uses a ESS Sabre 9018K2M per channel, it is also impressive at their guesstimate of a price tag I am unable to disclose. Also to our liking is the balanced headphone output. They were showing a 4 pin mini XLR, like what Audeze uses for cable but we made a point of saying a new balanced connector is the last thing this hobby needs so I am hoping they change to something more traditional even if this connector is much more robust than some of the current options. It also has some functions like bass and treble control, which are not up my street and the option to select either a digital input or an analogue input. There is certainly potential here but with it being their first venture into this sector, nothing is certain just yet. I will be watching this develop though.

Bass and Treble switches are not for me but gain is great to see.

The volume control in the middle had a unique feel to it.

It was certainly nice to see an upcoming IEM company here along with all the big boys and we hope to see them again next year, hopefully with some more stuff!
