Denon AU-320 Step Up Transformer For MC Phono Moving Coil Cartridge

The Denon AU‑320 is a vintage moving-coil (MC) cartridge step-up transformer from the 1970s, designed to interface MC cartridges with standard moving-magnet (MM) phono stages. It offers selectable impedance settings of 3 Ω, 40 Ω, and a bypass mode, making it compatible with two turntables and various MC cartridge types. Housed in a rugged iron case with triple-layer shielding, it features gold-plated terminals and low-capacitance circuitry to minimise noise and signal loss. Praised for its exceptional bandwidth, low noise floor, and quiet operation, the AU‑320 remains a sought-after, purely passive solution for vinyl purists who want a clean, analog signal path without introducing distortion or noise.

Simple, sturdy, and gets the job done
Installation was quick and straightforward. The adjustable straps hold equipment securely and make it easy to fit different sizes without any issues. The included drywall screws feel solid and provide a sturdy mount once installed. Overall, it’s a reliable and versatile solution for organizing electronics. The only minor downside is that Velcro straps might have been a bit easier to work with, but the current design still works well and feels secure. Definitely a good buy.

Quality mount for hiding devices
Never thought of a product like this before for mounting larger devices on the wall behind a TV. This worked perfect for a WiFi modem for a customer and held the very large device with ease and with only two large horizontal straps. If I could recommend anything, it would be to put a level on the mount for those of us that utilized it by mounting it 90 degrees to its normal mounting. Good thing I brought my levels (I always do) and it was a breeze to mount.

Works well, but it doesn't come with drywall anchors
Bought it to wall mount my wifi router. The whole thing is very small, but the straps are very long, so it can support many devices. The straps also get reasonably tight. Installation is easy, it's nice that it comes with a level. Annoying that it only comes with six screws, and no drywall anchors. So you either have those, have to go get them, or screw it to a stud (which you probably should do depending on how he heavy the object you want to mount is).

Clean, sturdy way to mount a cable box/router (easy install)
Used this TotalMount to get my cable box/router off the shelf and tidy up the setup behind the TV. Install was straightforward (screws/anchors included), and the mount feels solid once it’s on the wall. The adjustable fit is the best part—it held my device snug without bending or wobbling, and there’s still enough airflow so it doesn’t feel “choked” in place. It also helps a lot with cable management since everything stays in one spot instead of hanging or sliding around. Tip: measure your device first and lightly tighten, then do the final snug once it’s centered. Overall, great value if you want a cleaner, more organized setup.
