## Description

Fosi Audio Replaceable Control Knob Orange Controller for V3 Amplifier Stereo Amplifier Home Audio

Review: What can I possibly say - other than it's a knob, but a very well made one at that - When I ordered my FOSI Audio V3 months ago, it did not come with the gold colored knob (just the black one), however, that black one was milled out of solid aluminum (not like many of the cheap plastic coated push-on knobs you may find in the after-market). So I ordered this gold colored one and just like the very solid black version, this gold colored one is far superior to many other knobs on the market - whether stock or after-market. And you don't necessarily have to just use it on the V3 - rather, it can used on many other audio components and it will improve (for the most part) the appearances of those units. I'm thinking about getting several more of these for some of my Aiyima Amps. So $9 and something is nothing to worry about - but in the end, you get a high quality, nice looking knob. There's really nothing else to say - it's a knob - period!
Review: Orange? Please...it's off-copper! - I actually got this audiophile-grade knob as a freebie for buying a Fosi Audio V3 during Prime Days. As knobs go, this knob is very nice, indeed. As soon as you replace the stock knob with this lovely off-copper colored knob everything changes...the soundstage become bigger than the Grand Canyon, the bass takes on all the heft of 6.3 tons of concrete, and the highs sound like a chorus of barn swallows! Um...yeah. I love my new audiophile-grade knob! And FFS, it's not orange, it's off-copper! OK, off to go look at some $3K interconnects...

## Features

- The V3 amplifiers are equipped with replaceable orange knob. Customization of the amplifier's appearance, making it easier for users to tailor their setup to their individual preferences
- To replace the knobs, Just need a cloth with friction, simply grasp the existing knob firmly and pull it straight off the shaft. Then, align the new knob onto the shaft and press it firmly in place. Make sure that the new knob is securely attached before use
- Tips: The V3 orange knob only fits the V3 and is not suitable for installation in other amplifiers
