New to the two channel world - Advice needed on preamp

Another + for the Schiit Freya. Makes MUSIC.

dspr has given you good info. I am partial to CJ myself. however, ARC is a good choice as well. FWIW, I have a CJ PFR which I was waiting till fall to sell. It has been serviced, cleaned and  new  capacitors installed. this was done early this summer. I bought a CJ CT5 which is why I have the PFR. Email me if interested.  

given that you are playing at least cd quality stored on a ssd drive or streamed through a proper usb cable .the dac and preamp are very important to the total sound signature of the system .
cables:after proper component matching cables (rca/speaker)allow you a little more fine tuning sometimes it doesn't work like you hope... .a usb cable is not the same since cheap cables are not really made for audio so  get an entry level from one of the known companies .peachtree are a safe bet since they aim for pleasant sound and you at least solve the dac preamp issue and don't need to spend on interconnects. 
you can swap the 2 chinese 12au7 tubes for something like nos mullards(smooth and warm huge bass) or brimar(warmer less bass ) for 100-200$ and voice it more to the warm side and you have other options (nos are the best ).2 nice cheap small components are the loki eq and ifi itube2 tube preamp/buffer they will give more control over the tone and soundstage
