Burson OpAmps - Consensus?

I have used them in the past, and generally liked their improvement in sound. Some models were a bit bright for my taste and equipment that they were installed in at the time. I no longer use them. The biggest flaw I encountered was the melting of the decorative outer covers. The Burson op-amps really need space to breathe, and the ones with the colored decorative outer shells (95% of their models) shouldn’t be left powered up for over 48 hours straight. If you drive them hard, the plastic outer shell can also begin to melt. They really are great op-amps, and I think worth the price, but just be aware of their heat and space/height limitations. I don’t remember if one could remove the outer shells or not. I do think that should be an option.

That's a great point and consideration.. Thanks... I've been leaving mine on perpetually - I should check that! Appreciate it...

We just dropped in a pair of Opamps into a Cary 306 SACD player with excellent results.  Not very expensive.  I have not compared those to anything but the stock ones in the Cary but it was a significant improvement in sound wuality.
