Has anyone tried the Audioplex RCLL-1? It looks like does the same thing but not sure of the quality vs the cube.
Audiocubics R-cube remote volume control review
If you own some vintage audio equipment and would like an excellent way to control the volume the Audiocubics R-cube is just the answer. I recently purchased the R-cube from Curt at audiocubics.com. The R-cube consists of a simple, hand crafted 3"x3"x3" brushed aluminum cube. On the top front is a 192 color LED to give you a visual indication of the volume level. Below are the volume up and volume down buttons, and IR receiver. On the rear are the quality gold/teflon RCA inputs and outputs as well as the power adaptor plug. The remote control is equally impressive-carved from a solid hardwood with aluminum volume up, volume down and mute buttons. Construction of both the R-cube itself and the remote control are exceptional with great attention to detail.
Connecting the R-cube to your system:
For receivers and integrated amplifiers the R-cube inputs can be connected to the pre-amp outputs and the R-cube outputs can be connected to the amplifier inputs, with the bypass switch open or the jumpers removed. If there are no pre-amp outputs and amplifier inputs, a tape monitor loop can be used with the R-cube inputs connected to the tape outputs and the R-cube outputs connected to the tape inputs. For component systems the R-cube inputs can be connected to the pre-amp outputs and the R-cube outputs can be connected to the amplifier inputs or an equalizer, etc. If you use a single source of appropriate output voltage and an amplifier for a minimalist system, the R-cube inputs can be connected to the source outputs and the R-cube outputs can be connected to the amplifier inputs.
I have used the R-cube with both my vintage Marantz 2270 and Yamaha CR-1020 and have been more than pleased with the results. It not only looks beautiful, but works exactly as advertised. It seems to provide acoustically neutral remote volume control without any added noise what so ever.
Curt hand manufactures these and the quality shows. Although they are not cheap at approx. $200, the R-cube is dramatically less expensive (and I think it looks much better on the audio rack) than the Placette Audio remote volume control (currently about $1000), currently the only other option I am aware of that would provide similar results.

Curt is wonderful to deal with and manufactures a high quality piece of equipment. So if you've been looking for a quality remote volume control for your vintage audio equipment I highly recommend the R-cube.
