Tube Preamps Should Have This Feature

I've heard "Life is what you make it" but I never got the instruction manual.

I have an original version Freya and have never worried about its warmup time and I listen to the tube section exclusively. I like the fact that it doesn't turn off the tubes when I switch to one of the passive settings as its a great way to see if the tube stage is getting tired...instantly. Also, I still haven't found any remarkably better preamp at any price (I've owned some great preamps, and compared my Freya to various other things)...to claim it isn't as good as other more expensive stuff make no sense to me...its considered Class A to many.

Freya+ gives you the tube/no tube (buffer or no buffer w/o tubes). Pro-Ject Pre Box RS2 Digital also has a selectable tube preamp output (along with 2 DACs and a headphone amp)

Most short delays at startup are built-in safety checks, my McIntosh SS Amp, mc2250 had a test sequence; My Cayin Tube Integrated AT88is like yours, nothing possible for 30 second check; and my Little Luxman Tube Integrated has a 30 sec test.

Do they advise waiting 10, 20, 30 minutes for warmup in their manual: NO. 

Do we go with the well touted warmup concept, YES

Use your ears, it would be nuts to deny yourself some casual short time listening to some enjoyable content for lack of warmup.

My friend had car trouble, he will come next week.

My Conrad Johnson Premier 14 preamp came with exactly that sort of stand-by - the tubes are not active until you unmute it.
