I had been eyeing Avantgarde speakers for years, and finally purchased a pair of Uno Nano G2 back in 2015 for my ~50m^2 room where glass double entry doors can be closed. I have a number of different amplifiers including Pass Labs XA30.5, Kora Galaxy, Kora Flash. ARC Reference 3 preamp. Source gear includes VPI turntable with van den Hul Condor XCM cartridge, Nottingham Spacedeck with Dynavector 17D2 cartridge, PS Audio Stellar Phono Stage, Oppo BDP105, Cambridge CXN streamer. Also using BPT power conditioning, a JL Audio Fathom F113 subwoofer, and a variety of cables from Cardas, Nordost, van den Hul, and others. Avantgarde has the best customer service - my cabinets developed a finish issue a couple of years back, Armin and AG quickly sent me brand new cabinets to the US and worked with me through the entire replacement process. Unbelievable service, one of the best I have encountered in high end audio. When properly set up in the right size room and after the break in process, these speakers are quite amazing in all respects.
