Douk Audio VU3 PRO

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.

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.

I had a great experience with this seller. The condition,the quality and the appearance of my item was impeccable. The delivery was quick, and the packaging was sturdy with superb quality and appearance matching the item's description and images. The product met my expectations, and I believed it was worth the cost. I highly recommend purchasing from this seller.

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.

Works great. allows me to have 2 receivers, and 2 sets of speakers hooked up together. Can switch easily back and forth.

For anyone who A-B compares Amps to 1-2 sets of speakers. Lighted VU meters and remote. Also has a albeit front mic to measure room power. VU meters are adjustable and color of the back lights. Clean and professional looking, great for speaker builders who wants to compare amps to your new builds vs reference set. Gold plates connectors on the rear.

Did not work for my needs. Meters barely move even in microphone mode with volume up quite a bit. In wired mode, you have to turn up the volume high to even get the meters to show a reading.

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.
