Round 9: Unique Melody Legacy, Mentor and Miracle; ATH IM03; ATH IM70
Unique Melody Legacy ($1600)
After my experiences with the Rooth flagship IEMs, which I’d felt had fallen rather short, I wasn’t expecting much with the UM branded earphones. After all, they’re sister brands under the same company. The Legacy- a twelve driver flagship with limited distribution- was the first I tried. It was smooth and warm, but still retained quite good clarity. The bass was a bit rounded and a tad light- but not adding much punch actually fit well with the overall smoothness. Similarly the treble was silky- absolutely no trace of sibilance. The mids were just a drop dry, a tiny bit recessed, and an ounce lacking in air. More generally, the soundstage was nicely sized, and imaging was also quite good. One thing that could be improved- these seemed to have a strangely sandwiched image. Overall, it also seemed to be almost straining at times- very strange for a twelve-driver.
Unique Melody Legacy Score: 9.4-9.5
Unique Melody Mentor ($1449)
The Legacy had already performed better than the Rooths that I’d auditioned, so I was feeling quite positive now. I was on a roll, and the Mentor did not disappoint. It was definitely brighter than the Legacy, although overall still slightly warm, and with the silky smoothness of its older brother. In terms of the frequency response, the bass hits hard on the Mentor, and brought good punch and weight. The mids were well balanced- neither forward nor recessed, and neither lush nor dry. There was also good clarity here, and this was certainly helped along by a treble more aggressive and edgy than that of the Legacy. This also meant that the Mentor was the airier IEM. Imaging and soundstage was on par- but more impressive here because of the more forward sound.
Unique Melody Mentor Score: 9.6
Unique Melody Miracle ($1049)
The first thing that struck me about the Miracle was its well-rounded, sustained mids- definitely not dry, and with good airiness. The bass here is punchy and snappy- very good, although just a glimpse lighter and less authoritative than the Mentor. Which one you prefer may simply be a matter of taste. Up top, the treble is less edgy than the Mentor. Still energetic, though. As with its siblings, clarity continues to be good, and the smooth house sound is evident. The warmth- while still there- shows up least on the Miracle. Soundstage here was the biggest of the trio, although the differences were not big. Imaging was about equal.
Unique Melody Miracle Score: 9.6
ATH IM03 ($300)
The IM03 had a presentation that was a bit warm, and overall quite natural. There is also very good balance- none of the frequencies stand out more than the other, and they are all well matched in terms of their forwardness. The bass was not of the punchy variety, and speed was just okay, but it nonetheless served up good texture and detail. The mids were a little dry, and lacking in airiness. The treble is actually quite weak. Overall, the IM03 falls behind in PRaT and rhythm. It also had a peculiar soundstage- in terms of pure size, it falls in between ‘above average’ and ‘quite big’, but unfortunately seems to achieve this by making the sound a bit diffused.
ATH IM03 Score: 8.9-9.0
ATH IM70 ($100)
The IM70 was warm and smooth, with quite a large soundstage. Unlike the IM03, the bass is weighty and impactful. This warmth also comes without an edgy high-end to compensate. Instead what you get are smooth top notes with good clarity. Indeed, clarity is pretty evident throughout- which is very impressive for an IEM with this type of signature. In the midrange, the presentation is more forward, and is not lush, although airiness can be better. Overall, this was a very organic, clear, smooth and effortless signature.
ATH IM70 Score: 9.2-9.3
