New to the two channel world - Advice needed on preamp


I am new to the two channel arena, but have been in AV my entire career. I am looking to find a solid preamp to match with my system.   I would be open to integrated amps if they are a better option.

Current Rig

Paradigm Prestige 85F’s and Prestige 1000SW Sub (Not sure if I really need a sub or not, but I have it nonetheless)
Bryston 4B-ST
Sony ZA3100ES (I know its an AVR, but it had the requisite preouts)

I listen mostly to FLAC files off of a PC. Looking to stay under $2K. Any advice for a newbie?

Pick yourself up something like a nobsound ns-05p to start . compare any preamp to that first . You may save yourself 2k that you can put elsewhere . For $50 every single audiophile should try one . This is for digital though 
Thank you for the tips!

dweller - The BAT you mention is $8K.  Is there a model that is closer to my budget that would serve me well?

maple - looks interesting.  I’m going to order one off of eBay and see how that sounds.
Try jbl nano patch or schiit sys passive preamp. If you need a remote the schiit saga s is quite cheap and has a passive mode as well
The rotel rc1590 will answer any prayers for best sound and configurability . The built in dac is smooth as silk . Also has a number of inputs both digital and analog to grow with any budding audiophile .

sound quality is every bit as good as my mac system. I have both .
Loo looks like you have a credible system. Thinking tubes or solid state? You might try adding a tube pre-amp. I have an Audible Illusions L3B and love it. Check out my other posts under “Rongold”
