波士頓（Boston）UP-118E PE是施坦威設計的高端立式鋼琴，擁有118cm高度。其優點在於繼承了施坦威的核心設計（如低張力琴弦、優秀的寬尾設計)，音色測試彈奏後表現出泛音豐富、柔和靚麗等立式琴非常少見的品質。特別是音區的共鳴有一定深沉空間，比較接近於三角鋼琴的音色感覺。
至於手感行程校準 (Specs)鍵深如果嚴格控製在 10mm-10.2mm，防止下沉過深導致疲勞及斷進也調至 1.5mm-2mm 極限值，提升靈敏度與弱奏控製等缺點及止音器延遲等環節完成調整後，既保留了波士頓的音色張力，又大幅提升了操控的靈敏度。
Boston UP-118E PE is a high-end upright piano designed by Steinway, with a height of 118cm. Its advantage is that it inherits Steinway's core design (such as low-tension strings and wide-tail design). After playing the excellent tone test, it shows rich, soft and other very rare qualities of vertical pianos. In particular, the resonance of the sound area has a certain deep space, which is closer to the tone feeling of the grand piano. As for the hand feel stroke calibration (Specs) key depth, if it is strictly controlled at 10mm-10.2mm, it can also be adjusted to the limit value of 1.5mm-2mm to prevent fatigue and interruption caused by too deep sinking. After the adjustment of shortcomings such as improving sensitivity and weak control and the delay of the stopper, it is not only retained The tone tension of Boston has greatly improved the sensitivity of control.
