Don Sachs all in pre.  
Or you can get an LTA integrated or separates and have plenty of cash to spare.  I have the Don Sachs paired with the LTA ZOTL 10 and its stunning.
“Didn't even know there were any good ones for under $15k”?
Ummmmmm! Yes, there are a few. Example, Cary Audio SLP-05 with the Ultimate Upgrade.
check out the article on Stereophile. You don’t have to pay $20–80K to be the best sounding

I'm about to pull the trigger on the LTA z40 intrgrated amp.  Coming from SS or D class, I'm told I will be blown away. 
Lots of things come and go in my system but the Don Sachs 2,pre amp stays for less that 3k it will compete way beyond its price point in the 7k to 10k category 
EAR 912

I came from a ARC Ref 1 and the EAR is a better sounding unit in my system, to my ears. 
A stunningly good piece of gear. Tone, texture, soundstage and PRaT are spot on. I have it driving an Einstein The Power Amp. Great combination. 
I listen to Jazz, Rock, Classical, Pop, Bluegrass, Ambient...
