I just noticed, you are highlighting your question toward Preamps.
I had McIntosh SS C28 Preamp, highly regarded by many. I much prefer my McIntosh Tube Tuner/Preamp mx110z to the C28 (or any prior Preamp).
mx110z’s MM Phono (2) is wonderful, I use a SUT for MC to keep using the mx110z MM Phono.
you also get McIntosh's Versatile Mode Switch, balance, loudness for low volume, ...
If it died, even though they have gotten pricey, I would get another one without hesitation, ship it from seller directly to Audio Classics!
