Thank you Laurence, the unit works very well with the speaker arrangement I have and has a clear sound, it has brought new life to these since my amp blew many years ago. Vaughan

Just thought I’d give a bit of feedback on the Fosi LC30 since it’s a newish gadget.

I collect vintage speakers and amps and this is the best thing ever for comparing audio in real time, our audio memory is extremely short and you cannot really compare two systems if you have to manually switch speakers, amps and source.

Switching between amps or speakers on the LC30 is instantaneous and there are no relay clicks or anything, it just happens. The “VU” meters are rated in watts output so are very handy for equalizing the volume of the two amps being used.

Took a bit of figuring out how to get one audio source playing into two amps at the same time but a bunch of RCA cables and splitters eventually sorted that out.

Lovely products. Great price and fast delivery. No hassle shopping. I will definitely be coming back
