Drat! And just when I was starting to enjoy my tube system. :^)
Didn't they ask the same question when transistors first came out? "Will transistors make tube amps obsolete?" Here it is 40 years later, and tubes still rule. So, I guess I wouldn't hold my breath on digital amps taking the market by storm. After all, we're still waiting for them to make good on their first digital promise, "Perfect sound forever". Hasn't happened yet, after 20 years. So I'm even less likely to expect much from their second digital promise.
