Review: Fantastic Product for audiophiles - Looks good ,well designed and built like a tank
Review: Super products from Fosi Audio - The Fosi LC30.....a useful little Amplifier Speaker Selector. Being a diy speaker hobbyist, I own many a speaker. Auditioning different speakers and amplifiers has always been a problem. But then comes the LC30...it lets me toggle between speakers and amplifiers with ease. And it comes with a remote at that. The large VU meters give it a bit of a classic vintage look. The VU meters by themselves have adjustable sensitivity and brightness and the yellow is quite pleasing to the eye. It serves it's purpose to the T. I also own a pair of ZA3 amplifiers and some V3 Monoblocks that I use for HT purposes. The ZA3 and the V3 Mono are absolutely superb. Good clean power. I use iFi Audio Zen 2 DAC for my music predominantly streamed on Tidal. The sound is clean and rich and not at all overpowering or over bright throughout the music frequency range. All in all....I can say that all the ZA3, V3 Mono and the LC 30 are superb products and worth their price. Good VFM. Awaiting more good products from the Fosi stable...

### ⭐⭐⭐⭐ Nice vintage appeal.
*by P***D on 22 February 2025*

Apart from it's indented purpose of two amp & two sets of speakers selector this product has a nice vintage appeal to it. How ever there are a few drawbacks that I noticed in last few months of usage. The meters are not so easy to read. It would have been nice if these were like the real vintage type amplifiers (very light yellow dial with less numbers written), simple and easy to read. The sensitivity of the needles is very dicey. At half rotation of the knob and at moderate vol of Amplifier the needles touch the far end of the meter giving a fear that meter & needles will get damaged, my amp is 90w per channel (8ohms). The finger print/impression that comes on the paint finish of all Fosi audio products and this product is no exception so I have put an acrylic sticker film on top to make it less prone to finger prints. One great thing with this product is it let the signal pass in "off" condition when used for amp selection B and speaker selection 2. Can be powered by a normal 5V 1A charger easily. I am using the inbuilt usb in the spike guard/power strips and has not faced any issues till date. The remote is very handy, wish it could control the sensitivity knob rotation, the only drawback of the remote.
