Short test for the SMSL Q5 Pro & Canton Chrono 502 bookshelf speakers
Amplifier: SMSL Q5 Pro amp/DAC
Source: Nokia 808 & FLAC
Recorded with Olympus E-M10 Mark II microphone, slight echo & residual noise due to the room
The recorded sound sounds a little thin with little bass /due to the camera mic/ - the actual sound is slightly warmer, enough bass, slight backward mids and nice highs - that's with both BASS & TREBLE at 0 dB
