Review of the RSL Custom Set + Z150 MC boards 6 Dec 2022 by MS in Essex, UK: "I’m now three weeks into the new boards and I have to say that I’m amazed at how they’ve run in. I honestly consider them to be the biggest upgrade I’ve made; it’s as if a heavy curtain has been lifted from in front of the speakers. I would highly recommend your boards to anyone with a 72 pre-amp; everything is clear now, but still just as musically involving, perhaps even more so. I’m hearing things that were previously inaudible and recordings that had seemed flat (for example Watermark by Enya) are now brimming with life! Well done you and thank you so much!"
Review of the RSL Z302 remote control 25 June 2022: "A real must-have! I bought it several months ago for my Naim 32.5. I wanted to replace my Avondale board with something with a remote control. So now, I have a remote control and a RF one! What I did not expect was such a jump in term of sound quality. Bravo!"

A note about the photos on this site: since this site was hacked a couple of years ago, the administrative program no longer works.

"This is the best upgrade I’ve ever experienced, regardless of cost, and (in conjunction with a modified HICAP) bests my previous NAC272/XPS combination (itself a great performer) comfortably, making music sound ... rather more like music. " (R.T. in Nottinghamshire UK, October 2018)
New versions of MC (shown below) and MM plug-ins now available.
The latest MC plug-in has upgraded circuitry for clearer, more dynamic sound plus the ability to set your own cartridge compensation values. Covering the range from 54 to 560 ohms and with both 1nf and 6.8nf capacitance available, you can easily adjust your settings for the very best sound quality. Click on the image below to find out more.
The latest MM boards will arrive shortly and will include adjustable input capacitance. From 0pf through 367pf in 47pf increments. Although 100pf is industry standard, some cartridges can benefit from modification. Any orders placed after 17 May 2021 will have the latest version shipped. That means MM boards will ship after about 28 May 2021.
