MC/MM phono preamp guaranteed to work, just tested for a couple hours on some vinyl and everything sounded pristine/perfect. I upgraded the tubes in this unit awhile back also, so the unit sounds tip top as I tested a bunch of different tube brands and settled some specific tubes that sounded the best in my very legit vinyl listening room. If youre serious about vinyl and your listening experience look no further. Ive used this lightly for a couple of years and am moving to a smaller form factor. This thing is built similarly to $4k+ phono preamps. The company is still in business but they no longer make this model and it wouldnt surprise me if its because they werent making enough profit, its built like a tank with 2 separate power supplies for each channel for complete separation/isolation between channels. There are a few minor scuffs on the backside of the preamp but the front and top look pristine. Im an experienced shipper so this will be packed very very well and shipped via Fedex ground. If you have zero experience with vacuum tubes you should read up before purchasing this. Vacuum tubes are similar to incandescent light bulbs and will burn out over time depending on use. You should also make sure to power this device off when you are not using it. I have a couple extra power tubes Ill ship along with this, no guarantee they work but Im pretty sure theyre new and have never been put into a unit before.
