Best tube preamplifier for under $15k

I like the 27 SET preamplifier, but it has to have DC for the cathode heaters to silence hum and it is very tricky for its plate power. I like the blue glass Arcturus 27's and they sound good too. You have to build your own. You can also use 2C22's in choke loaded mu follower.

Buy this and your will have a world class preamp and world class phono

Lots of choices to consider. 

I would suggest checking out the Thomas Mayer 10y Line Preamp. I think this is one of his best known products. 

Each unit hand built to your specs by him personally. You can select for what combination of inputs and outputs, chassis wood and paint scheme, he may also give choices on input and output transformers. It can run 10y VT-25 tubes, 801a VT-62 or his own Elrog 801a tubes.
Also transformer volume control is standard which is very rare. The build quality and parts selection are at the highest level. If you are outside the EU you can deduct the 19% VAT from the price. To the US and without pricey options it would cost about $10k. https://www.vinylsavor.com/en/products/line/

His all silver and differential models cost over $15k

JUst wondered how you guys would rate the Accustic Hybrid Pre.
Thanks

Cary Audio SLP-05 with the Ultimate Upgrade.  List price is just shy of $11,000; however, through Carydirect.com, you can purchase it for just under $7,000.  With the money you’ve saved, I’d upgrade the eight (8) stock 6SN7 tubes.
