Tubeyist sounding Pre-amp?


What pre-amp has the most tubey sound?

I don't even car if it HAS tubes - I just want that sound - it can use MOSFETs for all I care.

" Do you 5 channels? Does anyone need 5 channels?"

If you speakers allow for it, you can use 4 of the 5 channels and do a vertical biamp. 
Thx - I see there was one on here but it sod.

My guess is that there is no magic, but a certain circuit topology and some MOSFETs involved....
The schiit saga is a new product $350 preamp. With your $500
budget it leaves some room to tube roll, although I’m not sure a single tube will deliver anything close to a fat sound.

my other suggestion would be a bottle head kit. 
A remarkable thread so much truth spoken. Agree strongly that most modern  tube pre amps sound is, fast, clean clear,  not rolled off or syrupy- unless you want them to be !  Cut to the chase, I recommend the AE-3 by a division of Cary.  They are no longer in production so buy used.  I did for less than $500.  They use the ubiquitous 6SN7 try a few brands of the old production tubes. Fair warning tube rolling can be addictive.  
I have no personal experience with Mapletree but have heard only good things about him.  They use octal but can be varied from the typical  assortment of audio tubes.
