I have the HA-160DS paired with some Q701’s with a PC as my source. I auditioned a lot of gear and kept coming back to the 160DS. This combo produces an amazingly transparent, uncoloured sound.
As with HiFi gear, I like pure, transparent sounding speakers with no exaggerated frequencies, and get the warmth I enjoy from the amp and DAC combo. The Q701’s punch well above their weight and pair nicely with the 160DS.
Moving up in price the DS is simply gorgeous paired with LCD-2’s or HD800’s but I couldn’t stretch the budget that far just yet. Hugely satisfied with the sound, very nicely made piece of equipment.
