Just about any but the cheapest stand alone phono stage will blow away every phono card ever made. Any.
I either don’t follow or don’t agree. As a designer, if i have a high quality power supply, box, and attendant hardware already there, for free --- making a superb phono board is relatively easy and inexpensive - I can deliver $1500 performance for $500, even being lavish with components.
Nothing changes except an independent box has vastly more cost, and a bunch more wires and plugs to degrade the sound. And take up space. Oh, and the fancy faceplate you can point to.
There’s a reason for stand-alone phonos, but they are not automatically superior in any way.
For the record my dedicated phono stage, plug-in card and preamp with integrated phono were all the same circuit. Not similar, same. Once i optimized it, what was i supposed to do, make one worse just so they were different? It didn’t save any appreciably money (unless i went to a cheap-ass design, and guess what -- that still doesn’t save that much, the PCB is the single largest cost anyway - if you make them in the USA)
