Sound Quest SQ-84 ..... if all you really need is 10 watts this amp will supply them. The amp doubles as a headamp and is impressively quiet even with higher sensitivity headphones like my senn 595's. The sound is punchy, clean and clear and quite musical. This amp is an excellent value and if you use new production tubes the tube cost is very reasonable. I am using the JJ Tesla 6v6s for the outputs and this is one of the best sounding new production tubes I have tried; $46 for a matched quad. The nos 6u8's used for the input and driver stages are inexpensive at around $5 per tube.
