Looking for a 300b integrated amplifier kit for my Avantgarde Trio (107db) horn speakers


I am interested in building myself a 300b tube integrated amplifier for my Avantgarde Trio (107db) horn speakers.

Any advice or pointers to the best kits? 

My criteria:

Super quiet
Super reliable
Amazing sound
Remote control

In your search for a 300B integrated amp kit I would strongly suggest you consider an Elekit TU-8600. You can find the kit for around $1200.00 without tubes at V.K.Msic or Tube Depot my suggestion would be VK as you get Victor Kung’s help and suggestions as part of the deal . The build is pretty straightforward although I made a stupid/ rookie mistake that Victor trouble shot for me . 
 My own TU8600 is fitted with Gold Lion outputs a Telefunken 12AX7 and HP5963’s in the 12AU7 position. It’s driving Zu Omen MKII’s or LS3/5a’s , and works well with either speaker in my large ( but lively) listening room. The Zu’s with their 97DB efficiency can play quite loudly in my 27’x19’ room while maintaining that exquisite 300B sound. The LS3/5a’s reach more modest levels but the amp really brings out the best in that lovely little monitor. I am familiar with Audio Note kits and believe you’ll find this kit comparable for substantially less money.
Found this site interesting and he has a 300b kit for $1,700. w/o tubes.
No interest in building one though.
