FOSI AUDIO GR 70 & IM 4 REVIEW

Описание: This isn’t sponsored. I bought the Fosi GR70 tube amp and IM4 open-back IEMs with my own money. Yes there are affiliate links, but they don’t buy my opinion — they just help keep the lights on.

The GR70 is NOT a DAC. It’s a tube headphone amp and pre-amp using reclaimed vacuum tubes, and this video puts it through studio monitors, reference headphones, and proper A/B switching to see if it actually performs or is just another budget hype product.

🟦 ABOUT THIS CHANNEL
I’m Peter Thomson and The Audio Lab is all about honest, real-world audio from someone who’s spent decades in broadcast, music, and live production. No snake oil, no mysticism, just straight testing and listening.

🟦 STUDIO TEST CHAIN (Critical Listening)
USB-C DAC → GR70 (Tube Pre) → CLA-100 → A/B Switch
CLA-10s vs Polk ES10
Avantone Planar II
Audio Technica BPHS1
Fosi IM4 vs Rock Lobster IEMs


🟦 WHAT THIS RIG IS (AND ISN’T)
This is a fun, affordable way to get tube flavour without stepping into boutique “mortgage-level” hifi pricing. If you want hyper-clinical accuracy, this isn’t the chain. If you want warm, smooth, and non-fatiguing playback at sensible money, this lane makes sense.
