REDGUM BLACK RGi35ENR Integrated Amplifier Review
Why Fins on the Bottom
Set Up and Listening

I wanted to compare the 24/192 and DSD downloads of Shelby Lynne’s Just A Little Lovin’ for a while now, and when I did, the results were interesting. The REDGUM allowed me to hear precisely the difference in the two formats. The 24/192 version was “wetter”, with more recorded detail. It was easier to hear the reverb around her vocal, and the specifics of her distance from the microphone. The DSD was smooth, more tape like, sacrificing a bit it detail for a warmer, inviting sound. Having been a Shelby Lynne fan since 2000, I also highly recommend the new deluxe remastering of her “breakthrough” album I Am Shelby Lynne.

Switching gears completely, I pulled up some Dave Brubeck. The wonderful Concord On A Summer Night, 24/88 FLAC, is beautifully recorded and the playing is sublime. I did not expect such delicacy and finesse from the REDGUM. Silly me. Brubeck’s miraculous touch on the piano was intact, and I ended playing this album through multiple times.

Determined to see if the REDGUM amp had its limits in sophistication, I played Tinariwen’s new Live In Paris, 24/48 FLAC. The exotic stew of desert rhythms, modal blues, and syncopated percussion made it impossible to sit still. This album also showcased the amp’s way with bass, as notes stopped and started on a dime. Staying on a world music path, I pulled up several Dhafer Youseff albums. The sheer depth of beauty in his music is hard to describe. His blending of North African soul and modern flourishes are ravishing and the REDGUM presented a clean window into this artist and his vision.

One last listening note I can add is the harder I pushed the amp, the more it gripped the speakers. There was no loss of coherence at room overloading volumes. And at lower volumes, nothing was lost either. There was lots of usable volume range, something I don’t always see with integrated amps. No worries here.

Ergonomically, the RGi35NR was an absolute dream. II had it running for ten weeks, on 24/7, and not only did it not generate heat, it was cool to the touch, even on some warmer Southern California late fall days. This is proof that Ian Robinson’s design choices, although off the beaten path, are spot on. If I had one complaint, it is a rather petty one. I wish the remote was a bit bigger, for those with clumsy hands.


If you are shopping for an amplifier to drive just about any speaker, that offers world class sonics, stylish design, and superb build, the REDGUM Black series is a must audition. To be quite, frank, there is no integrated ump in the price range of the RGi35NR that I can recommend over it.

If you need even more power, there are two other models to choose from. If you are running Magnepan speakers, or similar, and have been dissatisfied with your current amplifier, REDGUM may have your solution.  An audition is highly recommended, without reservation.
