The PA-One+ easily handled the ramp up to the higher impedance LCD 3s reproducing a stage-side table at a dinner theater atmosphere for Dean Martin singing “Everybody Loves Somebody” [Everybody Loves Somebody in 24-bit/96kHz], with a natural laid back depiction of the upright bass, drums, and piano accompanied by an enveloping string section and a healthy choral group.
To test the balanced output I selected the MrSpeakers ETHER2s and a 24-bit/96kHz vinyl rip of Nicky Hopkins’ “No Time” from his epic album No More Changes. The piano had an authentic tonality set in a large hall, while the bass guitar was deep and palpable, the lead guitar sweet and melodic, as the steel guitar and organ provided a haunting ethereal background.
Listening to “Killer Klowns From Outer Space” by the Dickies [Killer Klowns From Outer Space in 16-bit/44.1kHz] on the 1MORE Triple Driver Over-Ear Dynamic Headphones the dynamic drivers did what dynamic drivers do, create an exciting and dynamic presentation, and the PA-One+ mellowed the sometimes strident high frequencies produced by the budget headphone.
