Nice little preamp. I'm not sure if the tubes do anything.

I took the risk and decided on a cheap tube preamp. So I looked at all the small tube preamps and after reading the reviews settled on the Audio FX. I ordered GE pears or reeds, whatever you want to call them. I didn't even bother with the cheap tubes that came with it. I screwed the tubes between the Marantz preamp and the Emitova amp. The sound seemed a bit softer and the stage a bit bigger. I had no way to compare A/B. Then I remembered that my CD player has an optical output. So I compared…

I like FX-Audio Tube-03

My system: NAD C162 preamp, Acurus A250 power, Klipsch R-610F After comparing to NAD I will use this one because it sounds a bit nicer. I would like to share my experience in the following way. I wanted more control for the high end and I'm happy with this 03 tube because it has more high end than the C162 (maybe it's because the C162 is old and not pumped up). I bought GE 5654W tubes for sound comparison and found no improvement over 6K4. I get a slightly thicker voice and slightly louder…

Pros
  • ♪ SEPARATE BASS AND TREBLE CONTROLS — The tube preamp can independently adjust low frequencies and specific levels of components in the high-frequency sound to achieve ideal hi-fi effects. At the same time, it can maximize the atmosphere like a musical performance to meet your experience of different sound styles in the pursuit of sound quality.
Cons
  • Lots of things

Pretty decent little headphone amp

I originally had a homemade tube amp that was. Well, that's to be expected from a cheap kit. Eventually something happened and this DIY kit stopped working in one ear. I could never understand what happened. Changed dachshund and bought this amp as a replacement. This little guy is awesome! I like that it not only has a volume control but also a slight EQ treble/bass adjustment. I should have started with that. Take the time to customize it to your liking, it's worth it.

  • Price

  • Something's wrong
