I’d always rather have a separate preamp. I know DAC / Preamps are hugely popular but I wonder how many are just climbing the DAC ladder and have never had a really good preamp that meshes well with all their other gear.
My last two preamps were a CJ and Zesto. System sounded thin and honestly not that great with just a DAC driving my amps. I tried it with several DACs and put the preamp right back on the chain.
