Have you tested this against dedicated streamers, Innuous, Grimm MU1, or even just NUCs? I have a 2Go and have always been curious about adding the 2yu.
I compared it with several others items that can stream but mainly I wanted playback from my FLAC lossless collection, music from 50s to today, rock pop electronic and classical works, with a bit of Qobuz and Deezer to fill in.
1-samsing galaxy s23 ultra in flight mode using UAPP output via usb which was really surprisingly good with no odd cellular noises. Seriously more people should try this as it's cheap if you already have an andriod phone with usb. No mains loop helps it a lot.
2-samsing galaxy tab s8 ultra in flight mode with UAPP via USB, ever so slightly better than the phone and more convenient to use as it wasn't my phone, usb charging so unplugging every night to recharge, great screen, no remote control, d'oh!
3-Pi2aes with 5v power mod, using ifi elite 5v mains psu, tried usb, bnc, rca spdif and finally optical, wasn't impressed as it had the hf glare and forwardness of mains loop interaction due to ifi's brain dead decision to connect dc barrel ground to mains earth, which with Cornish mains wiring scheme raises the rf noise coupled into the device powered it by a clearly audibly and thus unacceptable margin, using an earth removal cheater plug and optical lessoned it but ethernet still provided a ground loop so not avoidable.
4-cambridge audio 851n streamer, great app interface, wireless hopelessly unusable with incessant drop outs, ethernet ground loop gave horrible hf glare.
5-unplugged 2go from my hugo2, slapped on 2yu, GoFigure'd, MALP for control, great sound via usb, optical a bit darker with superb hf clarity, DIY'd a pack of ikea nimh AAs into a 5v ish power supply gave excellent sound with same level of improvement as battery gives M-scaler with DAVE and meant I could use usb as it sounds identical to optical re hf glare and DSD material can be played, result! Made up a 20Ah NIMH pack with D cells, sounds identical but lasts 2+ days.
I listen to it for hours some days and it doesn't fatigue unless the material is rough which unfortunately it is with rock and pop from 80s 90s being most variable, most stuff sounds like the band is in my room or head or I'm there with them in front or around me, recording dependant presentation, some recordings are just flat, some amazingly 3d, some all over the place and even these I still enjoy, all have that vinyl like PRAT with some having amazing seperation and layering that DAVE does so well.
I've decided I can't be arsed listening to every possible streamer out there as bit perfect with really low jitter and no mains loops seems about good as it gets and spending more on them at this moment seems unnecessary.
Headphones- DCA Stealth (superb!), Sennheiser HD600 marble top.(nice but soft), HD800 1st Ed (spacoius but still soft), IE900 (yuck!), Beyer dt990 original 1988 (fun for antique rock), Hifiman Susvara maybe later this year.
Speaker- Genelec 8361A W371A complementary mode calibrated to flat as possible 20-20k at listening position, superb but still hearing the room signature overlaying everything compared to clearly not hearing it with headphones.
Obviously YMMV
