Stay with the Lehmann. Quiet, clear, dynamic, handles any cartridge. I kept the Cube in rotation with several high-buck phono stages over the years (Herron, cj premier 15, Xono) and it never embarrased itself. Often I preferred its deep tight bass and black background to the tubed units. Still have a PWX version (I cannot say it is THAT much better than the wall-wart version) which has finally been humbled by my current Groove and Ear 324. I haven't looked around at lower-priced phono stages for 10 years or so, but I do believe the Cube is one of the great values in audio.
Understanding phono stages/What to look for?
Everything from little boxes to full size components. Very few reviews. What should I look for. I have purchased a Black Cube to use with a 30 watt tube integrated. Although I have not been home yet to audition any of it. Why the huge differences in phono stages? I am using a Nottinhgham Interspace w/Rega tonearm OM20 switching soon to a Dynavector 20 low output MC. Will I want to stay with the Lehmann? Lots to learn, Louis
