Review: Amazing tube amp (which is one of the easily available and cheapest for me to get on desertcart) - I have been following fosi products. There are mixed reviews on Reddit and youtube some just branding it as cheap chifi setups. I wanted a Bluetooth transmitter and I was eyeing on fiio but that was costly so this was another option. I didn’t need an amplifier though. So this preamp was a good option. I personally like old vintage songs and warmth. So tube amps were a good option for me. The only question was whehter the build quality and sound quality would be good? Once I received, I connected it to my studio monitors and I could understand the warmth from the tubes. Then I listened to it by connecting on my IEMs, warmth is noticeable. The music becomes more enjoyable to hear. Soundstage is not that wide. But the bass and treble controls are really nice. Bass noticeably gets boosted at 12 o clock position. The volume button increases non linearly. It has enough amplification for IEM that I never get past the 12 o clock position, so I guess it would be able to drive full sized headphones also. One con would be when there is no electricity and when I play it on the inverter there is a hissing sound (some kind of weird earthing issues Iguess, because same thing happens for my studio monitors also) Conclusion - it has impressed me with the sound quality and build quality. Maybe better tube amps will be out there but this one is a good starting point.
Review: Neat. Great for its price. - Lovely little piece. Was messing with my beolab 4000s and decided to buy this on a whim. Its tamed my speakers, made it more mellow and warm. Love the sound. Needs to be cranked up a bit to drive them though
