This amp just arrived this morning here in Zambo City.
Out of the box, this 15-watt el84 pp amp sounded as loud as my Rotel 70 watt amp (RB03) driving the 84db Mordaunt Short 3.10. The music presentation was very pleasant, lacking the aggressiveness of the Rotel. This is what I expected from a tube amp. The bass was not as full and deep as the Rotel amp, but is likely to improve after hours of use.
