Rosson Audio Design RAD-0 - Alex's Beautiful New Baby

I emailed info@rosson.audio and asked for a FR graph they emailed back pretty quick and here it is.

 

[Beagle]

They aren’t Audeze heavy and won’t slide off. It’s little more clamp force but HE1000 comfortable.

Good to hear. I wonder how they compare to the Acoustic Research.

any sound impressions

 

[Bonddam]

I’m not ready to give sound impressions. I’m also waiting for cable by Rosson audio to arrive, ordered 4 pin xlr that they just made on request.

Unfortunately, this graph doesn't really tell us that much, because it looks like it has had a compensation curve applied to it. A FR graph with the raw response is what you want.

Also, I hope the starting dBSPL level for these is not correct. Because if it is, it would mean that these headphones are only 81 dB/mW, making them even harder to drive than the infamous HiFiMAN HE-6 and Susvara, which are rated at only 83 dB/mW and requires a minimum of 1-2 Watts just to wake them up!

It’s says unsmoothed, not sure if there is any curve applied. Could be wrong though

 

[XERO1]

Unsmoothed just means that the tiny peaks and dips (which are usually just fractions of a dB each) of the FR measurement haven’t been removed or ‘smoothed over’.

Ahhhhh ok I see what you mean.

What a big improvement with the XLR cable Rosson audio made for me. They should offer this as an option.

Would you mind posting some impressions of the headphone?

 

[Bonddam]

The Rad has great low end, mid bass is good. Mid range and higher seems Neutral.

i assume not many heard it, but would like more detailed comparisons

Me too. Would like to know how they stack up to Audeze.

to be honest i am bit surprised for lack of info, as it was at canjam i assume, i thought lot of people would give some impressions but apparently not

I’d love to hear just one comprehensive impression. I’d buy one just to try it but I can’t even find a return policy on their website.
