beginner seperate system

U.S.A. made Schiit Freya preamp, 3 instantly switchable modes resolve any mystery regarding tubes vs. solid state (passive, FET, and tube)...balanced and single ended ins and outs...I’ve had one for over a year and it sounds great, and there’s actually nothing like it. 700 bucks or so, their class A/B Vidar amp is the same price. I run my Freya into a Dennis Had SE tube amp and the sound is astonishingly good through efficient speakers. I also own a couple of Schiit Magni 3 headphone amps, and a Loki EQ...all very well built and designed by smart guys.

wolf, a while ago I watched/listened to a you tube which compared the difference in sounds between the Freya preamp modes.  I know that you tube is not way to test anything, but all three modes, SS, tube, passive sounded remarkedly the same.  Do you hear much difference?

I was gonna ask about shiit audio as its american made and priced in my range...also seen some chinese tube amps on amazon...Im not looking to play tubes very loud well I guess if I like em alot they will be played loud :)

Are you looking to replace the NAD amps or just needing a preamp?  You have a pair to NAD 275s bridged and a speaker system (Focals and subs). Looking to add to this with a budget of 2K.

Sorry, meant to erase the last two statements leaving only the question.
