Aesthetix Io is hard to beat, especially the Eclipse version. I was lucky to find a basic version for a fair price used, twenty years ago, and liked it so well that I upgraded to Eclipse and two power supplies. This was costly, but I have no regret. My version has aux as well as phono input, and volume control, so it can be used as a stand alone preamp, for analog plus a digital source (sounding very good). It has a personality however. The better the tubes, the better the sound. If you use costly NOS tubes - especially - it needs to be shut down when not in use, and it takes half an hour or so to warm up when you turn it on. It is a pure tube solution, and you need a fairly robust output from the cartridge to avoid background tube noise. Mine is 0,56mV, but I’ve seen claims that it works fine with less output also. And you need space for two - or three - full size boxes.
If you cant find (or afford) an Io, consider a Rhea, as a first step. If you like that sort of sound, you can later trade it for an Io.
