Tube Line Stage around $5k

+1 on considering the PS Audio. I dont have any experience with their BHK stuff but I did run their S300 for years without a hitch and it was a great amp for what I paid for it. The BHK pre is $6.5K new but there is a used unit on USAudio mart for a purdy good price.  I am sure they  get some of the compenents from APAC but I have been in their facility as its just down the road from my house and I am pretty sure all their BHK stuff is assembled right here in Boulder and many parts are sourced here in Colorado.

"I need a "destination " preamp ... " 

I've had three of those now since I was your age.

The Aesthetix Calypso or Pallene would be a great match with your Quicksilver amps and will meet your criteria. There is no information on the Pallene on the Aesthetix website but it'svessentially the premap section of the Mimas integrated and has options to add an internasl DAC ond phono stage. Good Luck!

tvad made a great recommendation with Aric Audio. I run a Motherlode II in my main system. It puts a huge smile on my ears everyday.  Aric is very passionate about the gear he makes. He is also great to work with. I have three of his preamps.    

So to reiterate,  nothing against anything like PL, in fact I think its really good stuff.  

I have an OPPO player , built in China, great unit.    I just happen to like made in USA.... I have stuff made in Germany and Canada too eh...

So thanks to everyone for their great suggestions.   I called Backert and spoke to Andy.   Picked the phone up right away.   I appreciated his time  so thanks to those guys

I actually pulled the trigger on a New In Box......  Zesto Leto Line Stage.    I am taking the chance that while NIB everything is OK which I'm sure it will be .  

Before clicking Buy , I called Zesto just to see what the hourly rate is just in case DOA and its pretty reasonable.   So fingers crossed.....
