Allnic Audio HA-3000 Phono head amp

Listed here is a pretty amazing and unique piece of equipment that I purchased as a dealer demo. It's the black version of the Allnic HA-3000 head amp, which uses a bunch of tiny tubes. It takes the interconnects from your turntable using an MC cartridge and amplifies it up to the level of an MM cartridge so it can be run into your phono preamp (or line level MM input) without using a step up transformer (or bypassing the step up transformer in your phono preamp for MC cartridges). This is considered by many one of the weak links in phono preamplification. I found that using it with my phono preamp added made a significant change in the quality of the sound, particularly in the midrange and treble, making it sound more natural and effortless. The professional reviews of the HA-3000 give you much more detail than I can about what it is and what it can do for you. Although I really liked it, I have moved my system in a very different direction and need to sell this unit. I have the original box and power cable.
