When designing the V3 Two-Channel Integrated Amplifier, Fosi Audio tried something a bit different than most Amazon brands, they asked some audiophiles what they wanted in a budget amp.
$42 for a tube preamp sounds insane; it seems way too good to be true, I mean $42? Really? I didn’t expect much from the Fosi Audio P1 Tube Preamp, but it was on sale on Amazon and had a coupon as well.
