Review on 🎧 Sabaj Da3 Portable USB DAC & Headphone Amplifier: SABRE9018Q2C OLED Screen, DSD512, 32bit/768kHz by Leah Jackson

love this little guy. I found it sounded better on my 400is in balanced mode. I haven't tested it extensively, but I noticed something. It seems that the balanced mode can be the main mode of operation. Update: compared balanced output to unbalanced output on he400i, he560. Definitely a huge difference. Everything is clearer and drives both sets without any problems. Then I connected thx789 from Massdrop. Easy. Both are designed to work in balanced mode. I am temporarily using the sms idea to power a srm252 to drive a stax sr-l300 and a sr-l300 which is limited as the power supply only accepts single ended RCA inputs. Save for 353x, which requires a balanced one. Da3 didn't sound as good as the Stax idea. The fact is that the device is designed for either balanced or unbalanced. So far two dual output devices where the unbalanced output mode sounded worse than comparable devices with only unbalanced output. This is great for balanced devices but I would go with the smaller Sabage or SMS idea which is the same for unbalanced devices.
