get one of these for $60.
It is passive, dead silent, and compatible with balanced and unbalanced cables. It played very well with my Cherry mono amps that are Class D.
Then, put the rest of your budget into the best DAC you can find. Save some more here buy obtaining a preowned unit.
I have also had a Nuprime DAC-10 which is a preamp/dac and would recommend you take a look at one of these.
@jjss49. I realize it has been covered, but my 500 watts at 8 ohms, and 1000 Watts at 4 Ohms is in my opinion a different and unique set of circumstances for home audio in my experience. I remember having computer audio setup through my laptop, and occasionally a full volume burst of noise would come through. This was with 50 watts per Channel. At 1000 watts per Channel I would lose my ceramic Accuton drivers. So I would rather run the computers volume wide open, barring clipping oh, and have a volume control for regular use. I do know how to use the search function though. I will use it when I can. Thanks for helping
@nsm1979... thank you for your reply. This is kind of what I've been thinking. While I have seen the Small Tube preamps under $100 on Amazon, I figured they were all real trash. You make me figure I should go ahead and try one though. What I would really love, is to be able to build and all tube gain buffer 4 less than $300.
