Best Tubed Preamp For A Warm, Rich Sound, Yet Still Detailed and Agile


As the title says, I am looking for an exceptional preamp (obviously tubed) with warmth and liquidity, some of that golden glow, in the midrange and highs. I do not want slowness, or lack of detail, however. My budget is up to $6,000.00, for a used model. 

Based on my research, many of those that might make the list are very rare to find, and other recommendations would be greatly appreciated.

Im comparing a Top of the Line Fully Loaded MP-1 to a MP-3.

I suspect if you got the MP-3 with the upgraded resistor package and the Vcaps throughout with Regulation it would come closer.

I third Don Sachs' preamps! Terrific quality. Tremendous sound.

Don is a great guy to deal with.
 
I put in my order with Mr. Sachs yesterday, and am looking forward to having one of his preamps in my system.  It will be paired with a Bryston 4B that was reconditioned/ upgraded last fall.
