I think my Sansui automatically goes into protection mode for 5 seconds thereabouts before it switches on...I like it!

Close? 

 

On start-up, the power-on sequence I use is from source to amp; on power-off, from amp to source. I make sure the volume is zeroed out before I turn anything on and before I turn anything off. If I think there is any risk of a power-on surge from the amp, I also make sure the headphone is unplugged before I turn on the amp. Additionally, if I am trying an amp for the first time, I assume there will be a surge of some sort, make sure the headphone is unplugged before turning on the amp, and also use a cheap headphone to test whole the signal chain. If I am in a location where the utility power is noisy or unreliable, I will also consider conditioning and regulating it for line noise, surges, brownouts and overvoltages.

A number of high quality amps have this feature; of course, quite a few don't.

so how would you describe the sound?

To me they have probably 90-95 percent of the warmth of a very good tube amplifier but 100% solid state. They are Class A biased so all 70 wpc are Class A into 8 ohm or 140 wpc into 4 ohm. I use them to drive the mid / treble of my Legacy Audio Aeris. I have had them for 12-15 years and have not been tempted since to upgrade. I had Wilson Shen, the designer, update them a couple years back.

I do not think they have ever been marketed very well plus in this day, they do not have the audiophile jewelry appearance, much more functional, which is fine for me.

The Spec amp does the same. I'd still probably do the unplug thing every startup as I've read one too many HE-6 blown driver comments. No reason to take the risk.

One must also be careful when plugging it in when the amp is already powered up. Depending on the volume setting it can blow the drivers too.

 

The worst that happened to me was my amp was powered up when I upgraded my source to the latest firmware then did a factory reset. I forgot that the factory reset sets the digital volume to max. So when I played the first song, 60 tube watts @ 8 ohms had to be dissipated by the HE-6. What saved it was the 10ohm resistors in parallel that absorbed most of the power.

If you look at the female XLR, you will see that pin 1 is shallower than the other pins. Its because it is recommended to be ground. It makes contact first/last when connecting/disconnecting the male connector for safety. So one can use two 3-pin xlr connectors for left and right channels.

Thanks! the tube/SS sound quality is what intrigues. I am really not that interested in looks, if sound reproduction is great! A new S40 costs what some First Watts cost, but packs more power. I am really intrigued by these amps.

Sorry for my ignorance, but I thought that there was a chance you could short your gear if you plug in your headphones when the amp is powered up? Does turning the volume to zero mitigate this?

Depends on your connector. TRS can/will short on connection. XLR is much safer. Can't short the channels together, or short a channel to ground.
