I have just tried this combo and to me it sounded fantastic. The soundstage is maybe somewhat less precise than on some higher end amps, but the tonality is just perfect. The sound is delicate, effortless and precise. The bass is rich, deep and well controlled, mids quite smooth. Treble has no signs of harshness. I have noticed some sibilance, but that may well be the source material.
If there's enough interest in this combo, I can put together a more detailed review.
