The great sound of JVC FX-311 tuner

signal path: JVC FX-311L - Realistic Disco Mixer - Sennheiser HD580. JVC RC-555W sounds great as well using only one of its speakers (point source approximation). Philips Babette 12RL472 sounds amazing driving from tape out the Realistic Disco Mixer and Sennheiser HD580 headphones. How would the Philips IC TDA7000 sound with a bass equilised amplifier driving the Pleiades linoleum Auratone type cube speaker? According to datasheet TDA7000 goes up to 10KHz ie loosing one octave which may be a good thing of spectral balance as 2 octaves are lost in bass by the 5in fullrange speaker.
