After several months of thorough comparison with Mammoth Gold, he evaluated it as ``a killer cartridge that has 90% of the performance of Mammoth Gold overall,'' but also said, ``In terms of imaging, it may be on par with Mammoth Gold.''\u003cbr\u003eRegarding the low frequencies, it is described as 'filling the entire room with gut punching.' In the IMPEx record organ recording, it was highly praised for 'shaking the room with layered resonance and resolution unlike anything heard before.' It is reported that the violin and reed instruments were reproduced sweetly and lustrously, and the vocals were warm and accurately reproduced. Additionally, it is noted for never being improper even with musically unremarkable LPs, and for the remarkable depth of character that allows any record to sing honestly and gracefully.\u003cbr\u003eThe essence of this device is summed up as follows: 'The imaging is top-level, and the depth of the sound stage is the same. The width is grand and dramatic. Despite the enormous sound, it is natural and never harsh or improper. Each LP sang honestly and gracefully.
