Both the Turning Points and the ERRs are excellent speakers that work well with the Torii. Amazing sounds from each. The Turning Points contain elements of a more conventional design coupled with the ambient, omni-directional nature of the Radial design. They offer a more detailed two channel presentation, and the ERRs a more omni-directional ambient presentation in my estimation. Coming from years of RL-1 and RL-2 use to the Turning Point I gained detail and a more conventional stereo sound, but this did not always serve all my recorded source material as well as the change to the ERRs did. When i received the ERRs I went "AAHHHH!" just like Goldilocks, the presentation was just right for me and the varied sources I have on hand. In my larger listening room they just have the edge over the Turning Points for me. In my second system, in my bedroom, the Turning Points are superb. The Torii Mk II there is slightly less detailed than the Mk III and the smaller room makes the more conventional presentation come to life in a way it doesn't in the larger listening space. I love them both, each can be the perfect speaker for the right room and accompanying components, AND considering personal listening styles and tastes. If you go for all the detail in the world and pinpoint imaging, the HR-1s have the edge. For an enveloping sound and a slightly more forgiving presentation the ERRs cannot be topped. I've fallen hard for the omni-directional aspect of the Radial designs--to me they are more accurate in a "live music" sense, and the HR-1s are more accurate in a faithful to a stereo recording sense.
You can't go wrong with either. I'm in an enviable position of having both! I need to protect my financial situation so that I always will!
I have tried my Torii Mk III with some other speakers, an old pair of built to survive a nuclear attack
Knight speakers, and a pair of Marantz speakers a friend of mine has (I gave them to him about seven years ago) and the amp works great with those too. The Knight are tight and dynamic in their heavy wooden cabinets, with a dry and crisp presentation. The Marantz are warm and yet very precise in a way that is very pleasing, but in comparison to the Decware speakers there are layers missing. The thing about the Torii Mk III when considering speaker choice I think is: it's a pretty brutally honest and extremely comprehensive amplifier. It can extract so much from your source and then pass that along to the speakers. Bot the front end and the speaker end will be asked to be on their toes and show you their best. All the good attributes will shine. And you won't be able to hide deficiencies easily. Speaker placement, component isolation, interconnect and speaker cabling, power treatment. . . all can matter. It can be a bit overwhelming if you let it. The trick is to find the musical heart of your system, and with the Torii Mk III you can. In some ways if you pay attention to the details you can make any components sing! And mostly in tune!
