The few times I connected a DAC direct to an amp it was definitely not a good match on my system. I immediately put a pre back in. Then last year I bought a really good preamp and it brought my system to the next level. Amazing upgrade to my entire system. I’m sure there are a few preamps in that price range that are pretty good. Especially if you buy a used one. I bought a leftover demo. It was actually like new for $3500. It was a $7500 preamp new. Could have never bought that new, that was even a stretch. Worth every penny
Buy the best preamp you can with your money, it is the heart of a good system
