Looking for a preamp with XLR connections

There's a lot of incredible preamps for $10k.  

• XLR connections doesn't mean fully differential balanced circuitry
• There are excellent solid state preamps and furthermore there are exception preamps "plus" that include phono stage, DAC or DAC/Streamer

I have Moon by Simaudio 390 and I think it's excellent.  I previously had a McIntosh C2600 which is a tube preamp and if money wasn't a consideration I'd probably went for a ARC preamp.

Listen to as many options as you can - there's certainly a number of strong options.  Enjoy the journey.

The AGD Alto Reference Preamplifier · AGD Productions

is a fully balanced design end-to-end

The Phono stage also uses a completely balanced design.

A preamplifier  is basically  the system.  It has to let what the source  sends it through and not change it. A poor preamplifier  can never have a system  sound right. Shop lots listen  to as many as you can before you  buy  

The Bryston BR20 is a fully balanced design. Plus great customer service. It also comes w/a 20 year Warranty.
