The R1.5 performs this task very well. The sound is dynamic, clear and controlled over the entire frequeny range, when driven moderatly. At very high power levels, it seems to loose control gradually. My speaker have a minimum impedance of 1 ohm at 20kHz, so I guess with loudspeakers having a more linear impedance, the problem woud be less.

Usher R1.5 and R2.5 were almost direct copies of the Threshold Stasis S200 and S300. I showed Nelson Pass the circuits of the Ushers, and the only difference was they had one extra gain stage transistor in them, which Nelson replied was what he would have done if he did a re-design of them.

Jul 3, 2009. #14. I have just bought a pair of the Usher R1.5's - originally bought a single amp based on reviews alone. I compared it to friends borrowed Primare A32 (costing over twice the price) - the Usher beats the Primare hand-down in terms of dynamics and bass-slam as well a delicacy in the upper and mid-ranges.

好猛的擴大機，之前都誤會他了！之前覺得usher r1.5總是推力十足，但不夠細膩，總有股「過硬」的感覺！就不耐聽。但這次usher 進了一台小dac ，整個音樂性就出來了，耐聽、滂礡又柔順！問了之後才知道，店家以前電腦訊源，都沒有上dac ，用電腦內建音效晶片直接接擴大機..(發燒音響 第1頁)

REVIEW Heavy Metal - USHER Audio Technology ČR & SR
http://www.usheraudio.cz/data/test/16-usher-r1-5-hifi-world-05.pdf
An extremely impressive bit of kit, by any standards, the Usher R1.5 makes an excellent ‘do-it-all’ high end power amp. From a consumer’s point of view it’s affordable Class A without tears, as you get none of the speaker matching issues that the Sugden A21a presents (due to its understandable lack of power).
