I have heard the Jolida 302B with M60s and they sound great together. I would also second the opinion on the Stingray as a fine choice as well. The Jolida can be found for $500-600 used on Audiogon or around $1,100 new (approx.). The Stingray varies from $1,100 - 1,500 used. I have not heard the Ming Da but I like the EL34 based amps in general. Rogue also makes some very nice amps.
