Usher R1.5 should I buy?
I have not received schematic. I have sent PM to the parties requesting. Hope all is well with vvvinashhh. georgehifi posted a fairly small resolution schematic here: http://www.diyaudio.com/forums/pass-labs/55067-usher-amps-lookalike-buildt-licence.html#post616009 less then desired; however, provides enough information to figure things out. I have an Usher R 1.5 incoming replacing a Classe Audio DR-10 which are driving VMPS RM-30 speakers. With my gear I like to have a schematic if anything goes wrong. PS: Good input from vvvinashhh on factory bias of the R1.5 is 500mA. In that same post I provided above there is a good discussion on process to increase bias. |
Hey Guys, Just wanted to share that I have the Usher 1.5 amplifier in my reference system right now. The amplifier was re-biased by the individual I purchased it from to a higher class A bias. This amplifier is wonderful! It easily is on the same level as highly regarded Pass Labs pieces and drops tons of current to really control bottom end frequencies. It's overall a touch warm/full with a sweet top end and great overall dynamics. The build quality regrading internal parts and chassis are excellent. This amplifier is a real "sleeper" when it comes to cost vs performance ratio. |
