Douk Audio VU3 PRO Dual Analog VU Meter, 2-Way Amplifier Switch, Speaker Selector, Amp Audio Switcher Box 2-IN-2-OUT with DB Panel Display

It does what I needed. I can A - B two sets of speakers (or two amps). And I can run both sets of speakers combined. That last feature is hard to find. The remote is handy for A - B comparing of speakers while sitting in the listening position. I like the banana plug / spade connectors. Solid and versatile. I have not noticed any degradation of sound quality when using this box. For $135 is was a good price. The meters are nice eye candy, but not all that acurate. You can change colors and brightness. Or turn them off completely if you wish. The unit does have to be powered on to pass the sound through you your speakers. I have a Furman power coditioner on my setup that I turn on before applying power to each hifi component. The VU3 pro is plugged into the Furman and it powers on when the Furman is switched on. So, that works fine for me. And the VU 3 pro remembers it's settings from the last power down. So, that's a good feature.

Looks cool, works great. The remote is kind of cheap and doesn’t respond the best but overall very nice unit.

This was just what I needed. Using a tube amp and solid state amp in the same system, I'm able to switch between the two amps and use the same pre-amp, speakers and everything else is worth the price of admission. Added bonus I could always add another pair of speakers in the future if I decide I need them (doubtful). Well made, looks nice, VU meters (their accuracy which is highly debatable, but it looks cool) an added bonus and ability to change the backlighting is nice, but hardly a requirement. There is no discernable degradation of sound quality.

This adds a great visual dimension to listening to music, it’s worth that alone in my opinion. As far as the switching function, it works flawlessly, switching between 2 amps and 2 sets of stereo speakers by remote control or manually. As far as I can tell on my hi-fi setup (nothing super fancy but definitely not cheap either) this unit is dead transparent, except for the audible click from the relays within the unit itself, which sounds like powering up a surround sound receiver. I was reluctant to make the purchase because I thought this was a lower quality product but I wanted VU meters. I was pleasantly surprised when it arrived, feeling solidly built in a metal chassis with a decent finish. My two complaints are that the screen will not go into the deeper shades of blue manually, only in rotating color mode and although the VU meters are very pleasant to watch, I can’t seem to get any accuracy out of them. It is at a great price for what it does as a switcher and visual entertainer, it’s just not an accurate, blue colored VU meter.

I purchased this device to replace an existing one, I use to switch between a Denon receiver I use for AV, and a Primaluna tube amp I use for 2 channel music. The box is well made, metal chassis, solid clicks when I switch between amps. VU meters are just eye candy, but brilliant. Love that you can change the color on try fly. Rear panel has good quality inputs. No degradation to sound that I can tell. One of the best $145 updates I’ve made.

Better than the other swithces that I tested. Quality finish and functionality. This switch does not add any color and the loss of output is very minimal or I can say negligible. Very userful for every audiophile to compare between to amplifiers to evaluate performance of two differnt brands of speakers instantly. In my case I was comparing and evaluating my new Yamaha A-S801 amp with my vintage Denon PMA-720 using a pair of KEF Q350 and a pair of Klipch RP600 M-II. It is so convenient and handy to switch between amps and speaker pairs while not changing your listening position , using the remote. Also gives a good look to your rack with the UV meters. I will definitely recomend this.

Great switching box. I can AB systems compare amps and speakers with ease. VU meters are cool. Love the remote. Doesn’t seem to color the sound.

Works as advertised but remote stopped working 8 months after purchase, vendor will replace for free but wants $10.00 to ship.

Excelente manufactura y muy fácil de usar

Received the product yesterday. The setup was a breeze and I did it all by myself. I used banana plus for the connections. It is working as expected and no loss in signal. The VU meters are bright enough and working fine. The Denon front two speakers out and the Pioneer Amps speaker out are connected to this. Presently one pair of Polk speakers are added. Switching works perfectly fine. I tested with both Amps. I am happy with the product.

Es bueno pero esperaba algo mejor por el precio

Really useful for interchange
