Hello,
In theory, that "combo", YAMAHA A-S2000 + SPENDOR A5, could be described as "dull" or "warm" sound.
But, there are also source and cables.
And, to my ears, that combination is sounding great for Jazz. Is there a better amplifier for the Spendor A5? Probably. But at what price/cost?
Here is how I descibe that combo for Rock music: I can listen to AC/DC for hours, with a moderate to high "sound volume" without any listen fatigue.
Here is the sequence of Sources and cables of what I'm doing with that Combo:
(Apple Mac Mini+Amarra+Flac 24/96) > Audioquest Carbon USB > (Musical Fidelity M1DAC-A) > XLR Blues Jeans Cable + TC electronic Potenciometer > (Yamaha A-S2000) > DNM Speaker Cable Solid Core Resolution > (Spendor A5).
Power Cord: Shunyata Venom 3 for DAC and YAMAHA.
Could the Spendor A5R be a much better option with that Source and Cables? I don't know and I couldn't listen to it before I buy.
Regards,
Custodio
