Just received mine yesterday. No smoke, no hum. It sounds good even with the stock tubes. I am using Sennheiser HD650. I have some NOS tubes coming which should be even better.

For this specific amp, NOS tubes may generate a slight hum/buzz during the first 50-100 hours of use. Proper tube conditioning is advised. Read my posts on page 5 for more info.
Otherwise, enjoy your purchase. Great sounding combo, I'm sure you'll be pleased :)

It isn't a slight hum by any means. U can do the simple mod which will help so u can actually switch tubes with ease. They really need to fix this in their design, it's easy and doesn't affect the quality and makes it possible to actually do some tube rolling without spending 100s of hours for each tube. Many tubes never got rid of the hum for me despite being fine in your amps.
