I have come across Peachtree Audio product and MANLEY STING RAY i-POD tube amp, of course the Stingray isn't cheap by any means $6500 OUCH!  
 
 
  I also looked into iTube 202 Tube Amplifier with FatDock Blu but I can't come up with any reviews on it.
I know that Peachtree has a nova65SE Amplifier which is priced at $799.  I want the ability to listen to my mp3, music streaming but also love the sound of tubes.  So I am trying to get the best from both worlds. Suggestion, advice greatly appreciated... 
Thanks~
