I just recived one from Underwood Hi-Fi with the Level-2 mod done by Part Connection. The reception is great and I am not using anythang but the wire antennas that came with it.The sound,well the Bass is fast & deep as the hi's are crisp & distinct, the sound is not muddy at all but full and rich more like a SACD and quiet when there is stillness over the air wave.Also it is not a light weight but built to last. I have to say I am quite satisfied with it and plan to do a little tube rolling (of course).
