Supratek or Don Sachs - which way to go?


I'm preparing to replace my SS preamp with a tube unit and have read with great interest many threads on this board. This is where I learned about Don Sachs model 2 preamps. They sound like what I'm looking for and those who own them consistently express their satisfaction with them.

Now I've just been reading and learning about the Supratek lineup. Wow. These also sound like fantastic works of art. Leaving me with a new question about which way to go. 

Thoughts? Advice? Experience? Anyone care to share?

So far I haven't noticed the power supply warming anything up. However, my new listening room is about 16 x 24 and I sit about 15 feet away from the shelving where the Cortese and other equipment are located.
How is the volume control on the Cortese, is it smooth, can you control it in small steps ? From the remote also ?
Just got a Sachs preamp delivered yesterday.  I'll post more after I've got a couple hundred hours on it, but first impressions are very positive.  
The volume control is super smooth and solid. It can be controlled from the remote. The "channel" buttons change the volume in smaller steps. The "volume" buttons are "normal", whatever that means.
OP: Congrats on your research and purchase decision. Neither unit is a slouch. But the WAF bonus is terrific. Well done. Enjoy the music!
