Tube preamp match with Solid Stare amp

@audioman58 I don't believe any of the current LTA preamps are truly balanced designs even though they accept XLR connections. You don't say what exact model you are recommending. At least a few years back when I contacted them that's what they told me.

The Linear Tube Audio top preamp retail before discounts around $6 k 

with the Lundahl transformer upgrade it maybe true balanced give them a call 

parts quality top notch !

Look in to Backert preamps. Transparent sound and a great preamp for my Pass XA30.8. Wonderful people to deal with, American made and beautifully crafted.

The LTA has no balanced outputs and is not a truly balanced design as @willywonka stated. I own the microZOTL and it is a great preamp, but does not fit what the OP was asking about - plus it is a line stage preamp.

Thank you for the Backert reference.  I am now familiar with a great product!
