The Quill Acoustics Satin is the debut IEM from the MusicTek venture Quill Acoustics. It is a 10 driver quadbrid 7BA, 1DD, 1BCD, 1MP configuration and retails for $3300 USD. I reviewed this using Lotoo Paw Gold as my source. Keep in mind Satin takes a good amount of power to drive thanks to those micro planars.
The Satin comes with a box with a written foreward by it’s co-engineer Leo from MusicTek. It includes a case with 4 different pairs of eartips, a cleaning tool for tips, a nice leather case with a custom PW Audio cable inside. The IEMs themselves look really nice with a beautiful sand dune inspired design on the shells – however the build quality itself has some issues with a few of my friends experiencing chipping on the nozzles so be aware of that.
Bass:
The subbass quantity and quality on the Satin is fantastic. It reaches very deep and has incredible depth and rumble to it. The midbass quantity is not so much but good enough to balance out the tuning of the IEM. I think this is definitely a more subbass focused rather than midbass focused IEM.
Mids:
The lower mids recessed, upper mids elevated is a common tuning in w shaped IEMs nowadays and Satin is no exception with pushed up upper mids being quite forward and quite detailed sounding. I think fans of vocals will be fine here as the mids definitely have good energy.
Treble:
Satin also has pretty nice treble that is also slightly elevated and well balanced to my ears, however it *can* feel sibilant or harsh to some on certain tracks, but only certain ones. Most of the time, it feels fine.
Technicality:
Satin is not lacking for resolution or detail as it can compete with any $3k or $4k level IEM on detail retrieval. However the Satin’s soundstage is a fair bit narrower than other IEMs in its class – I was comparing it to Nostalgia Tesseract and UM Multiverse Mentor and Satin definitely cannot match up to them in stage width or depth.
Overall the Satin is an excellent first effort from Quill, it checks all the right boxes and has a nice balanced tuning however I do wish the soundstage could be a bit wider and it *could* cause a bit of fatigue on some tracks. I also hope that Quill builds its shells better in the future as well as they do look really nice.
